Refrigerator Control Board FAQ

The only reliable confirmation is to match the part number on your current board's sticker to the part number on our listing. Your refrigerator model number alone is not enough. The same model was manufactured over multiple years with different board revisions. Two fridges with the same model number off an assembly line two years apart can require completely different boards.

If you are not certain, contact us with a photo of your board's sticker before ordering. We verify fit at no charge.

Your model number helps narrow down options but is not a safe substitute for the part number. Refrigerator models are produced over several years with running changes. Board revisions happen mid-production without a model number change. Matching your model number to a listing is a starting point, not a confirmation.

The part number printed on your current board is the only reliable match. Find it, use it.

The sticker is on the front face of the control board, not the back. You need to access the board by removing the rear access panel first. Here is where to find the board on each brand:

• GE and Whirlpool - behind the rear access panel at the lower back of the unit. Remove 4 to 6 Phillips screws to open.
• LG - rear access panel, lower section at the back of the unit.
• Samsung - rear access panel. On some French door models, there may be a separate display board behind the interior upper panel of the fresh food section.

Part number formats by brand: GE starts with WR55X. Samsung starts with DA41 or DA92. LG starts with EBR. Whirlpool starts with W10 or WPW10.

Manufacturers update part numbers when they revise a board design. The newer number is a direct replacement and fully compatible with any unit that used the old number. You will often see your original part number listed as a cross-reference on the listing for the newer number. If your old number appears there, that listing is the correct board for your unit.

Common example: Whirlpool W10317076 was superseded by WPW10317076. Both are the same board for the same refrigerators. Either number gets you the right part.

Yes. These brands are all part of the Whirlpool Corporation family and share board platforms with their parent brand. If your board's part number starts with W10, WPW10, or EBR, it is almost certainly in our catalog.

• Kenmore (Whirlpool-manufactured) - search by the W10 or WPW10 number on your board
• Maytag - shares board platforms with Whirlpool across most refrigerator lines
• KitchenAid - same Whirlpool board platforms, typically higher-end models
• Amana - entry-level Whirlpool family, same board families
• Kenmore (LG-manufactured) - search by the EBR number on your board

Search by part number directly for the fastest result.

No. They are completely different products. A generic or aftermarket board is manufactured by a third party as an approximate substitute. It may not have matching component tolerances, the same firmware, or the same communication protocols as the original.

Our boards are the original OEM board from your appliance's own manufacturer, professionally rebuilt. Same board. Same part number. Same fit. Same firmware. Not an imitation. Not a copy.

Not always. Error codes fall into two categories:

• Board self-diagnosis codes - the board ran its own diagnostic and determined it has failed. These are high-confidence indicators a board replacement will fix the problem. Examples: Samsung 88 88 persisting after reset, GE E2, Whirlpool F1 returning after reset, Whirlpool CF after UI board replacement.
• Component fault codes - the board is reporting that a sensor, fan, or defrost component has failed. The board itself may be fine. Examples: LG Er FS (freezer sensor), GE CI (ice maker), Samsung 5E (defrost sensor).

Every product listing on our site includes the error codes most reliably associated with that specific board failing. Check the error code section on the listing for your code before ordering.

New OEM control boards direct from the manufacturer or authorized dealers typically run $150 to $400+ depending on brand and model. Samsung and LG boards trend higher. GE and Whirlpool vary widely by model generation.

Our professionally rebuilt boards average 50 to 70% less than new OEM pricing with the same fit and backed by a 6-month warranty. For most homeowners, replacing the board is by far the most cost-effective fix compared to a $900 to $2,500 refrigerator replacement or a $300 to $600 service call using a shop-supplied part.

These are the most reliable signs a control board has failed:

• Refrigerator not cooling - compressor not running, fans running, no error code pointing to a specific failed component
• Error code persisting after a full reset - especially Samsung 88, GE SY EF or E2, LG Er FF or Er CO, Whirlpool F1 or CF
• Unresponsive control panel - display is dead or buttons do not respond, but the unit has power (interior lights on)
• Erratic temperature behavior - compressor running constantly, cycling abnormally, or unit not reaching set temperatures
• Code that clears and returns - reset clears it temporarily but the code is back within hours or days

This is one of the most common refrigerator symptoms and it is often NOT the board. Work through these causes in order:

1. Ice buildup on evaporator coils - most common cause by far. Unplug the refrigerator and leave both compartment doors open for 24 hours. If it cools again after, the defrost system needs attention, not the board.
2. Evaporator fan not running - listen for air movement inside the fresh food section. No airflow means the fan has failed or is frozen.
3. Air damper stuck closed - the damper controls airflow from the freezer into the fresh food section. If stuck closed, no cold air gets through.
4. Control board - if the above three check out and the board is not triggering the defrost cycle or controlling fans correctly, the board may be failing.

If an error code accompanied the symptom, use the brand-specific error code sections below to narrow the diagnosis further.

Power outages and voltage surges can trap the board in a fault state it cannot recover from on its own. If the error code clears after the reset and the fridge begins cooling normally, you are done. If the error returns or the refrigerator does not cool after 24 hours, the power event physically damaged components on the board.

Samsung and LG inverter compressor models are especially susceptible to voltage spikes. These models use an inverter-controlled compressor that is more sensitive to power disruptions than traditional compressor designs.

If your refrigerator is under 12 to 15 years old, replacing the board is almost always the right financial decision. Here is the actual math:

• Rebuilt control board: $79 to $199 depending on the model
• New comparable refrigerator: $900 to $2,500+
• Technician service call + shop-supplied new board: $300 to $600

Most refrigerators that fail due to a board issue have 10 or more years of useful life remaining. A board failure is not a sign the appliance is wearing out. It is almost always a single electronic component that failed, not a mechanical breakdown of the cooling system.

The only scenario where replacement beats repair: the refrigerator has multiple simultaneous failures (compressor + board + sealed system leak), or the unit is over 15 years old and the total repair cost approaches half its replacement value.

Most modern refrigerators have a built-in diagnostic mode you can run yourself:

• Samsung - hold Energy Saver and Alarm buttons simultaneously for 8 to 12 seconds. On some models, use Fridge and Freezer buttons.
• LG - hold Refrigerator and Ice Plus buttons simultaneously for 5 seconds.
• GE - varies by model; most use a door switch activation sequence. Check your service sheet (usually taped inside the unit).
• Whirlpool - hold SW1 and SW2 (the two left door-activated switches) simultaneously for 3 seconds.

Diagnostic mode displays active and historical fault codes. A technician with a multimeter can also measure voltage output at the board's connectors against spec. If you are not comfortable with either method, the symptom-plus-error-code approach is sufficient to make a confident diagnosis in most cases.

A board failure can produce zero error codes. When a board fails catastrophically, it often cannot complete its own diagnostic routine, so nothing gets reported. Signs pointing to a total board failure with no code:

• Compressor not running, fans not running, but interior lights work
• Control panel is completely unresponsive - no display, no button response
• No response after a full reset (unplugged for 10+ minutes)
• Unit has power but behaves as though completely dead

No error code does not mean the board is fine. It may mean the board is too far gone to report its own failure.

Your refrigerator is in demo mode (also called display mode, showroom mode, or cooling off mode). The compressor is intentionally disabled. Food will not stay cold. This is a setting, not a failure.

• LG - with either door open, hold the Refrigerator and Ice Plus buttons simultaneously for 5 seconds until the control panel beeps and temperatures display normally.
• Samsung - hold the Fridge and Energy Saver buttons (or Power Freeze and Power Cool on older models) simultaneously for 3 seconds until you hear a chime.
• GE - hold the top two display buttons simultaneously for 3 seconds. Varies by model.
• Whirlpool - refer to the service sheet inside the unit or your model's manual for the specific button sequence.

Demo mode is one of the most common post-delivery, post-power-outage, and post-board-replacement surprises. Check this before ordering any parts.

SY EF (sometimes displayed as 5Y EF on older displays) means the GE refrigerator control board has detected a fault in the evaporator fan circuit. The board is not receiving the expected electrical signal from the evaporator fan motor.

What usually causes GE SY EF:

• Ice buildup locking the evaporator fan blades in place -- this is the most common cause by a wide margin
• Evaporator fan motor has failed
• Wire harness between the fan motor and the control board is damaged, pinched, or disconnected
• Main control board has failed and cannot send or receive signals from the fan circuit

If GE SY EF returns after defrosting: check the wire harness connections between the evaporator fan and the main control board. If the fan motor tests in spec and wiring is intact, the main control board is the failed component.

GE CC means the freezer temperature has been above the normal operating range. The control board is reporting a temperature abnormality, not necessarily its own failure.

Common causes of GE CC in order of likelihood:

1. Condenser coils clogged with dust at the base of the refrigerator -- clean these first. This is the single most common cause of GE cooling problems.
2. Defrost system failure allowing ice to block evaporator airflow
3. Evaporator fan failure or ice buildup on the fan
4. Control board not triggering defrost cycles correctly

If condenser coil cleaning and a manual defrost do not resolve the CC code, the main control board may not be scheduling defrost cycles properly and could be the root cause.

GE FF is a fault code meaning the freezer temperature has been above normal for more than 2 hours. Check whether frozen food is thawing. Troubleshoot the same way as CC: condenser coils first, then defrost system, then evaporator fan.

GE tF is not an error code at all. It means TurboFreeze is active. The display shows tF (which can look like EF or an upside-down F with an F) to indicate the freezer is running a rapid cool-down cycle. If your food is still frozen and the fridge is cooling normally, tF is normal operation and requires no action.

GE E2 is a direct main control board error code. It means the main board detected a fault in its own internal diagnostic. This is a high-confidence indicator that the main control board has failed.

Unlike sensor or fan codes that point to external components, E2 specifically identifies the main board itself as the failed part. If E2 persists, replacing the board is the correct repair.

GE dE means the defrost system has not operated properly in the last 24 hours. GE DF means there has been no current detected in the defrost circuit for 48 hours. Both codes point to the defrost system rather than the main board as the primary suspect.

Check the defrost heater, defrost thermostat, and defrost timer in that order. However, the main control board is what schedules and initiates the defrost cycle on a timer. If all defrost components test good but dE or DF persists, the main board is not triggering defrost correctly and needs replacement.

GE HRS means the unit is stuck in defrost mode. The refrigerator ran a defrost cycle that did not terminate properly, indicating the control board may not be managing the defrost cycle end condition correctly.

A power reset (unplug for 5 minutes) will exit defrost mode and allow the board to restart its cycle. If HRS recurs repeatedly, the main control board is not completing defrost cycle management correctly and likely needs replacement.

Work through this checklist in order before assuming board failure:

1. Confirm the unit is not in demo mode (display should show actual temperatures, not symbols)
2. Unplug for 5 minutes and reset
3. Clean condenser coils at the base behind the front grille -- this is the most common cause of no-code GE cooling failures. Use a vacuum or brush.
4. Listen for the compressor running (low hum from the back/bottom) and the evaporator fan (air movement inside)
5. If both compressor and fans run but the unit is not cooling, the sealed system may have a leak -- this requires a technician
6. If the compressor does not run and there is no fan activity, the board is not sending power to these components -- the main control board is the likely cause

If step 6 applies after a reset, the GE main control board is the primary suspect.

LG Er FF (shown as E FF on some displays) means the freezer fan motor is not operating normally. This is one of the most common LG refrigerator error codes.

If Er FF returns after defrosting: the freezer fan motor has failed and needs replacement. If the motor is replaced and Er FF still appears, the main control board may not be receiving signals from the fan circuit correctly and could be the root cause.

Recurring Er FF codes after defrosting indicate a defrost system problem that keeps icing up the fan blades. The defrost heater or thermostat likely needs replacement to prevent recurrence.

LG Er rF means the refrigerator compartment fan motor (fresh food section) is not operating normally. This is the same diagnosis path as Er FF but for the fresh food section fan rather than the freezer fan.

Unplug, leave doors open for 24 hours to defrost, plug back in. If Er rF clears, ice was locking the fresh food compartment fan. If it returns, the refrigerator compartment fan motor needs replacement. Persistent Er rF after motor replacement points to the main control board.

LG 22E (or 22C on some display formats) indicates a fan motor malfunction. The control board is not receiving the expected feedback from the fan motor circuit. Unlike Er FF where ice buildup is the leading cause, 22E is more often a true component failure rather than a frost/ice issue.

If the fan blade spins freely by hand and the motor tests within spec with a multimeter, the main control board is not correctly reading or powering the fan circuit and is the more likely failed component on this code.

OF F or O FF means the LG refrigerator is in Demo Mode (also called Display Mode). The compressor is intentionally disabled. The refrigerator will not cool. Food will spoil if left in this state.

This is one of the most common post-delivery and post-power-outage situations that gets mistaken for a board failure. Check this before assuming anything is broken.

LG dH codes mean the unit spent more than 1 hour trying to complete a defrost cycle without reaching the required temperature at the evaporator.

• F dH - defrost sensor did not reach above 40 degrees Fahrenheit during a freezer defrost cycle
• r dH - same failure in the refrigerator compartment defrost cycle
• dH alone - defrost issue without specifying compartment

These codes typically point to a failed defrost heater or defrost thermostat. LG's official guidance: these codes require service and cannot be resolved by a reset alone. If the defrost heater and thermostat test good, the main control board may not be correctly managing the defrost cycle duration.

LG Er CO is a communication error between the main control board and the display panel. The two boards are not communicating. LG's official guidance: there are no DIY troubleshooting steps for Er CO. The unit requires service.

In practice, Er CO is one of the codes where the main control board is the most common failed component. Check wire harness connections between the main board and the display panel first. If connections are solid and the display board tests functional, the main control board needs replacement.

LG Er CF means the condenser fan motor (located at the bottom rear of the refrigerator, next to the compressor) is not operating correctly. The feedback signal from the condenser fan was absent for more than 65 seconds during operation.

The condenser fan pulls room air across the condenser coils to remove heat. If this fan fails, the compressor overheats and cooling stops entirely. Check for physical obstructions in the fan first. If the fan and motor test good, the main control board may not be powering or reading the fan circuit correctly.

LG Er FS indicates a short or disconnection in the freezer temperature sensor (thermistor). The main control board is getting an out-of-range reading or no signal from the freezer sensor.

When Er FS triggers, the main control board typically defaults to running the compressor continuously to prevent food spoilage. This can cause the fresh food section to actually over-cool or freeze. LG's official guidance: Er FS requires service. If the freezer sensor tests out-of-spec with a multimeter, it needs replacement. If the sensor tests fine, the main control board may be misreading sensor data.

LG refrigerators -- especially French door and side-by-side models manufactured between 2014 and 2019 -- have a documented issue with linear compressor failure. If your LG refrigerator is in this age range and not cooling with no error code, the compressor is a serious suspect alongside the board.

Signs it is the compressor, not the board:

• Clicking sound every few minutes from the bottom rear (failed start relay on the compressor)
• Compressor runs briefly then stops, cycling on and off every 3 to 5 minutes
• Unit is completely silent when it should be running

Signs it is the board, not the compressor:

• Compressor attempts to run but the board cuts it off
• No response from the board after a reset
• Er CO, Er CF, or communication-type codes appeared before cooling stopped

A technician with a multimeter can test compressor start winding resistance to confirm which component has failed.

Samsung 88 or 88 88 is the most common Samsung refrigerator error code. It signals a communication fault caused by the control board being disrupted during bootup -- most often triggered by a power outage, voltage spike, or surge. The board started a self-diagnostic, could not complete it, and locked up displaying 88.

Variant codes that follow Samsung 88 identify secondary damage:

• 88 83 - abnormal current detected at the compressor inverter
• 88 85 - voltage below normal operating range
• 88 86 - voltage above normal operating range

If Samsung 88 returns after a full power reset: the power event physically damaged components on the main control board. The board needs replacement. Samsung inverter compressor models -- which is most Samsung refrigerators made after 2012 -- are particularly vulnerable to voltage damage.

Prevention: Plug the refrigerator into a quality surge protector rated for large appliances. Samsung specifically recommends this for inverter models. A $25 to $50 surge protector can prevent a repeated board replacement down the road.

Samsung PC ER is a communication error between the display panel board and the main control board. The two boards cannot talk to each other. The display may be unresponsive and the refrigerator may stop operating.

Check the ribbon cable or wire harness connecting the display panel to the main board -- a loose connection is the easiest fix. If connections are solid, one of the two boards has failed. The main control board is the more common failed component on Samsung PC ER vs. the display board, especially if the error appeared after a power event.

Samsung 5E (displayed as SE on older 7-segment displays) typically indicates a defrost sensor error or ice buildup affecting the sensor circuit in the fresh food section.

A power reset clears 5E temporarily on many Samsung models. If it returns, check for blocked air vents or heavy frost in the fresh food compartment. If the defrost sensor tests out of spec, it needs replacement. If the sensor tests fine and 5E persists, the main control board may not be correctly managing the defrost cycle for the fresh food section.

Samsung 1E (or E1 on some displays) typically indicates a power outage or surge has disrupted normal operation. This code often appears after a power event alongside or instead of the 88 code.

If 1E persists after the reset, the board sustained damage from the power event and likely needs replacement.

Your Samsung refrigerator will not cool in this mode. Food will spoil.

On French door models with internal display, the button combination varies. Power Freeze and Power Cool held for 3 seconds is common on older models. Refer to your service sheet if the above does not work.

Samsung 8E or 8A (often displayed as 88 8A or 88 8E after an 88 code) indicates the refrigerator is not receiving rotational feedback from the freezer evaporator fan. The fan should be spinning but the electronics are not detecting its rotation.

This code is common after a power event that froze the board in the middle of a diagnostic. The fan may be physically working fine. First step: unplug and defrost (leave freezer door open for 4 to 8 hours to melt any ice around the fan blades), then plug back in. If the code clears, ice was physically stopping the fan.

If the code returns with the fan blade spinning freely by hand, the fan motor or the control board circuit that monitors the fan has failed.

All icons flashing on a Samsung refrigerator display is normal and expected immediately after the refrigerator is plugged in or after a power outage. The Samsung control board is running a self-diagnostic to verify all systems are communicating properly.

Wait 5 to 10 minutes for the diagnostic to complete. The flashing should stop on its own and the display should return to showing temperatures. If icons continue flashing beyond 15 to 20 minutes or the display does not return to normal, the board may have found a fault it cannot clear. Note which icons are flashing -- this can help identify the specific code.

Samsung 13E indicates a malfunction in the ice maker dispenser system -- specifically an ice motor or sensor fault. This code often appears alongside or after an 88 code on Samsung French door models that have taken a voltage hit.

If the refrigerator is cooling normally but showing 13E, the ice maker dispenser circuit is the isolated issue. The ice maker motor, sensor, or control circuit needs attention. If the refrigerator is not cooling AND showing 13E, address the cooling issue and main board first -- the 13E may clear once the board is replaced.

Two methods for resetting a Samsung refrigerator control board:

• Soft reset - unplug the refrigerator from the wall for a full 5 minutes, then plug back in. This clears temporary fault states including most 88 and post-outage codes.
• Hard reset / diagnostic mode - hold Energy Saver and Alarm buttons simultaneously for 8 to 12 seconds. On some older models, use Fridge and Freezer buttons. The display will run a self-diagnostic sequence.

If you are resetting after a power outage and the code clears but keeps coming back with every minor power fluctuation, a surge protector on the outlet will prevent this pattern from repeating.

Whirlpool F1 is a direct control board self-diagnosis code. The main electronic control board has detected an internal failure within its own circuitry. This is one of the most reliable indicators across all brands that the board itself -- not a secondary component -- is the failed part.

F1 is the Whirlpool version of what Samsung calls 88 and GE calls E2 -- a self-reported board failure code. If F1 returns after a reset, ordering a replacement board is the correct next step.

Whirlpool CF stands for Communication Failure. The main control board and the user interface control panel have lost communication and cannot talk to each other. The UI panel will not respond to button presses and the refrigerator may stop operating entirely.

Troubleshoot Whirlpool CF in this order:

1. Unplug the refrigerator and inspect the wire harness connections between the main control board and the user interface panel -- especially through the door hinges where wiring is subject to flex and wear
2. Look for pinched, frayed, or damaged wire insulation
3. Replace the user interface control board (less expensive component, eliminates it as the cause)
4. If CF persists after UI board replacement, the main control board is the failed component and needs replacement

Whirlpool PO (or P0) indicates a power outage has been detected. The control board lost power and is reporting the event when power was restored. This code typically appears after a power outage or voltage event and in most cases clears with a simple reset.

If PO returns persistently or the refrigerator is not cooling after clearing PO, the board may have sustained voltage damage during the power event and needs replacement. A surge protector on the outlet prevents PO and the board damage that sometimes accompanies power events on Whirlpool models.

C on the refrigerator display means the refrigerator compartment thermistor (temperature sensor) has failed. C on the freezer display means the freezer compartment thermistor has failed. These point to the temperature sensors, not the main board -- though the board may be misreading the sensor if the sensor itself tests within spec.

Flashing 6 on a Whirlpool refrigerator display is a general computer or software error code on some models. Allow the refrigerator to return to its set temperature on its own first. If the flashing 6 does not clear within a few hours and the refrigerator is not cooling, the control board may need replacement.

On newer Whirlpool refrigerators with two-part fault codes, F stands for the system that failed and E identifies the specific component:

• F3 E1 - defrost system fault, temperature sensor issue. The defrost sensor is reading out of spec or not reporting correctly.
• F3 E3 - defrost system fault, defrost heater circuit issue. The defrost heater is not completing the defrost cycle.

If all defrost components test good but F3 codes persist, the main control board is not correctly managing the defrost cycle and needs replacement.

Work through this checklist before concluding the board has failed:

1. Confirm the unit is not in demo mode
2. Unplug for 5 minutes and reset
3. Clean condenser coils at the base behind the front kick plate -- this is the top no-code cooling failure cause on Whirlpool and Maytag models
4. Listen for evaporator fan running (air movement in the fresh food section)
5. Check that the air damper between the freezer and fresh food section is not physically stuck closed
6. If compressor attempts to run but cuts out quickly -- check the start relay on the compressor (shake it; if it rattles, it needs replacement)
7. If none of the above -- the main control board may not be sending run signals to the compressor

If step 7 applies after a reset, the Whirlpool main control board is the primary suspect.

Whirlpool Corporation manufactures refrigerators sold under multiple brand names that share control board platforms. Part numbers starting with W10XXXXXX or WPWXXXXXXX are Whirlpool Corporation boards regardless of the brand name on the door.

• Whirlpool - the parent brand
• Maytag - shares the majority of W10 and WPW10 board part numbers
• KitchenAid - same Whirlpool board platforms, typically in higher-end models
• Amana - entry-level Whirlpool family
• Kenmore (Whirlpool-manufactured models) - use the same W10 and WPW10 boards
• JennAir - premium Whirlpool family brand

The board part number on your unit tells you definitively which family it belongs to. If it starts with W10 or WPW10, it is a Whirlpool family board.

Yes. Because Maytag and KitchenAid refrigerators are manufactured by Whirlpool Corporation using the same board platforms, the error codes are identical:

• F1 - main control board self-diagnosis failure
• CF - communication failure between main board and UI panel
• PO or P0 - power outage detected
• C code - thermistor (temperature sensor) failure
• F3 E1 / F3 E3 - defrost system fault codes

If you have a Maytag or KitchenAid refrigerator displaying one of these codes, the diagnosis and repair path is the same as Whirlpool. The board part numbers starting with W10 or WPW10 apply across all brands in the family.

For most people with basic DIY confidence, a control board replacement is a straightforward repair with no electrical knowledge required. Estimated time: 20 to 40 minutes for most models. Basic process:

1. Unplug the refrigerator
2. Remove the rear access panel (4 to 6 Phillips screws)
3. Photograph the wire harness connections before disconnecting anything
4. Disconnect wire harness connectors -- they are keyed and will only fit back in their correct positions
5. Remove 2 to 4 board mounting screws
6. Slide in the new board, replace mounting screws
7. Reconnect all harnesses in their original positions
8. Replace the access panel, plug the refrigerator back in

Tools needed: Phillips head screwdriver, flathead screwdriver. No multimeter or electrical knowledge needed for the swap itself.

The exception: specific Whirlpool JAZZ electronic control boards require a one-time programming step after installation. The board must be programmed to match the specific refrigerator model it is installed in. If your board requires programming, it will be noted on the product listing. Programming instructions are available through the Whirlpool Service Matters portal at servicematters.com.

Samsung, LG, and GE control boards do not require post-installation programming.

Work through this checklist before concluding the board is defective:

• Confirm the part number matches exactly - look at the sticker on the board you installed and compare it character by character to the part number you ordered. One digit off means the wrong board.
• Check every harness connection - each connector should be fully seated and clicked in. A half-seated connector will prevent the board from operating.
• Wait 24 hours - a refrigerator that has been off for any length of time takes time to reach temperature. It does not cool instantly.
• Check for demo mode - the board may have booted into demo mode. If the display shows OF or unusual characters where temperatures should be, exit demo mode using your brand's button sequence.
• Listen for the compressor - within 10 to 15 minutes of plugging in you should hear a low hum from the back or bottom of the unit.

If the part number is confirmed correct, all connections are solid, and the refrigerator still does not respond after 24 hours -- contact us. We will help diagnose whether there is a second failed component or whether the replacement board is defective. We do not walk away after a sale.

• Phillips head screwdriver (access panel, board mounting screws)
• Flathead screwdriver (releasing locking tab connectors on some models)
• Work gloves (recommended)
• 5 to 10 minutes with the refrigerator fully unplugged before touching the board (residual capacitor discharge)

A quarter-inch nut driver is useful for some Whirlpool and Maytag models that use hex-head screws on the access panel. No multimeter, no soldering equipment, no special appliance tools needed for a standard board swap.

Absolutely. Any qualified appliance technician can install a control board. Board swaps are one of the most routine repairs in their toolkit.

Bringing your own part is financially smart: you pay only for labor, not for a part that the shop marks up 40 to 100% above cost. Most technicians charge $75 to $150 for a board installation. On a part you purchased yourself at our pricing, the total repair cost is still a fraction of a new appliance.

One important ask: have your technician confirm the part number on the board matches your unit before installing. If there is any discrepancy, they should not install it.

A properly installed replacement control board should last the remaining life of the refrigerator -- typically 10 to 15 or more years. Control board failures are almost always one-time events caused by a specific trigger: a power surge, a manufacturing defect in a single component, or physical damage from moisture or heat. They are not a sign the appliance is wearing out.

The most important thing you can do to protect your new board: plug the refrigerator into a quality surge protector rated for large appliances. This is especially important for Samsung and LG inverter models. A $25 to $50 surge protector eliminates the most common cause of board failure going forward.

We typically ship USPS. Standard delivery reaches most customers in the continental US within 2 to 5 business days from the ship date. Expedited 2-day shipping is available at checkout if you need it faster. Your refrigerator being out of service is an emergency and we try to move as fast as possible on our end.

Yes. Free standard shipping on every order to the continental United States. Expedited shipping is available at an additional cost for customers who need faster delivery. Alaska and Hawaii shipping is calculated at checkout. We do not currently ship internationally.

Every board ships in a heat-sealed ESD (electrostatic discharge) anti-static bag inside a padded shipping box. ESD anti-static packaging is the same protection standard used by electronics manufacturers when shipping new boards. It protects the board's components from static electricity during handling and transit.

If your package arrives visibly damaged or crushed, take photos of the packaging and the board before installing it and contact us immediately. We will address the situation before you put a potentially damaged board into your refrigerator.

Yes -- and we actively encourage this. If you have any uncertainty about whether your part number matches a listing, contact us with a photo of your board's part number sticker before ordering. We will confirm fit at no charge and get back to you quickly.

This takes a few minutes on your end and prevents a return process that delays getting your refrigerator back up. Our goal is to get you the right board the first time, not to process returns.

Returns are accepted within 30 days of purchase. The board must come back in the condition it shipped. A restocking fee of 10 to 50% may apply to opened or installed boards depending on condition.

Ordered the wrong part number? Contact us and we will work with you. If you want to exchange for the correct board, we waive the restocking fee -- you cover return shipping and we get the right board out to you. At our price point, making the correction as painless as possible is important to us.

The warranty covers manufacturing defects and component failures under normal operating conditions. We determine repair vs. replacement based on what gets your appliance back up and running fastest.

Not covered by the warranty:

• Damage from incorrect installation
• Damage from electrical surges or voltage spikes after installation
• Physical damage from mishandling during installation
• Boards ordered with the wrong part number (this falls under the return policy instead)

Contact us through the store with the following:

• Your order number
• A photo of the board showing the part number sticker
• A description of what the refrigerator is doing or not doing

We respond within one business day and get the process moving from there. The claim process is intentionally simple -- you are dealing with a broken refrigerator, not a bureaucracy.

Returns accepted within 30 days of purchase. The board must be returned in the condition it was received. A restocking fee of 10 to 50% may apply to boards that have been opened or installed, depending on condition.

Ordered the wrong part number: we waive the restocking fee for exchanges. You cover return shipping and we ship the correct board. Contact us first and we will make it straightforward.

Board arrived but the refrigerator still does not work: do not automatically return it. Contact us first -- there may be a second failed component involved, or a connection issue. We will help you diagnose before you incur return shipping costs.

Not necessarily. Before concluding the board is defective:

• Confirm the part number on the installed board matches your order exactly -- one digit off means wrong board
• Confirm all harness connections are fully seated and clicked in
• Check for demo mode -- the fridge may have booted into it after the board swap
• Give it 24 hours -- refrigerators that have been off for a period take time to cool down to operating temperature

If all of the above check out and the refrigerator still does not respond, contact us with your order number and a description of the symptoms. There may be a second failed component, or the replacement board may be defective (this is rare but it happens). We do not leave you stuck after the sale.

Our 6-month repair-or-replace warranty is comparable to warranties offered by many third-party parts suppliers on new boards, which typically range from 90 days to 1 year. New OEM boards from the manufacturer carry 1-year warranties in most cases.

The practical difference: manufacturer and large supplier warranty claims involve shipping the board back, waiting for inspection, and waiting for a replacement. Our claim process is faster and more hands-on because we are a focused operation, not a call center queue.

Physical damage from installation -- bent connectors, cracked circuit board material, damage from forcing a connector in the wrong orientation -- is not covered under the warranty. These are installation accidents rather than manufacturing defects.

If you are not comfortable doing the installation yourself, having a qualified appliance technician do it costs $75 to $150 in labor and ensures the board warranty is protected. For a $79 to $199 board, the labor cost is a reasonable investment in protecting the part.

It means we went through the board with purpose: found what failed, repaired it at the component level, and put it back together the right way. Every board goes through:

• Visual inspection - looking for obvious physical damage, burnt components, corrosion, and signs of prior failure
• Targeted fault diagnosis - focused on the known failure points specific to that part number and model generation, not a generic pass/fail check
• Component repair - replacing the capacitors, transistors, relays, or other components that failed, not just the whole board
• ESD anti-static packaging - heat-sealed before it ships

It is not pulled from a junk unit, tested, and resold. It is diagnosed, repaired at the component level, and rebuilt to perform reliably again.

• Price - new OEM boards from the manufacturer typically run $150 to $400. Our rebuilt boards average 50 to 70% less.
• Same exact board - not a generic substitute. The original OEM board that came in your appliance, rebuilt. Same part number, same fit, same firmware compatibility.
• Availability - many older boards are discontinued new. A professionally rebuilt board may be the only option that is not a sketchy aftermarket knockoff.
• Less waste - a functional board rebuilt rather than discarded. Better for your wallet and for the environment.

The 6-month warranty backs every board we sell. If it fails due to a defect in that window, we fix or replace it. That is not a throwaway promise.

EcoSmart Appliance Parts is a real operation. We source OEM boards, rebuild them ourselves, and ship from our own inventory. We are not a marketplace reseller or a drop shipper routing orders to a third party. When you place an order, the board on the listing is the board we ship -- it has been through our rebuild process before it goes in the box.

Because throwing away a refrigerator because one circuit board failed is a waste -- of your money and of a perfectly good appliance. Most refrigerators that get replaced due to a board failure have 10 or more years of useful life remaining in the compressor, sealed system, and mechanical components.

EcoSmart was built on the idea that repairing appliances should be straightforward and affordable. We source OEM boards, rebuild them properly, price them fairly, and back them with a warranty that means something. That is it.

Plug the refrigerator into a quality surge protector rated for large appliances. This is the single most effective thing you can do to protect the board long-term. Especially critical for Samsung and LG inverter compressor models, which are more sensitive to voltage fluctuations than traditional compressor designs.

A decent appliance surge protector costs $25 to $50 and can prevent a future $150+ board replacement. Look for a joule rating of 1,500 or higher and UL listing for appliance use.

If your home experiences frequent brownouts or power fluctuations, a dedicated appliance-grade voltage stabilizer (not just a surge protector) provides a higher level of protection.
