Find Your Board by Part Number
💡 Your part number starts with EBR or EBX — find it on the sticker on your control board.

If your LG is showing Er codes, stopped cooling, or you've manually defrosted it and the problem keeps coming back — the control board is almost certainly the root cause. LG boards are a well-documented failure point across InstaView, Door-in-Door, and French door models. A dead fridge with food going warm is a stressful situation, and we get it. Let's fix it right. OEM LG control board part numbers typically begin with EBR or EBX — for example EBR75234713, EBR86093708, EBR81182702, or EBX61766401.

When an LG board starts failing, you'll see it in the display — Er FF, Er rF, Er dH, Er CO — or the unit will stop cooling entirely without warning. The board manages the defrost cycle, fan motor commands, compressor control, and ice maker logic. When it goes, everything goes. And because LG uses dozens of board variants across similar-looking models, the part number sticker on your board is the only reliable way to confirm the right replacement.

Here's the relief: A new LG OEM control board typically runs $180–$400 at retail. The same original OEM part from EcoSmart typically runs $65–$150. Same fix. Same OEM part. Save 50–70% — that's a steak dinner, at minimum.

We carry boards for InstaView, Door-in-Door, French door, side-by-side, and bottom-freezer LG configurations. Search by your EBR or EBX part number above for availability.

LG Refrigerator Error Codes

Seeing one of these? Your control board may be the cause.
Board often the cause Board may be involved
Er FF
Freezer Fan (Evaporator Fan) Failure
The control board is not getting feedback from the freezer evaporator fan motor. If the fan motor tests fine but the error persists, the board itself is the culprit — it is not sending proper voltage to the fan circuit.
Board Often Cause
Er rF
Refrigerator Fan Motor Abnormality
Refrigerator compartment fan motor failure or signal loss. After ruling out frost buildup, the main control board is the most common root cause — especially if defrosting manually clears the error temporarily.
Board Often Cause
Er dH / F dH / r dH
Defrost Heater Error / Defrost Failure
The defrost cycle did not complete — evaporator coils did not reach the target temperature within 1 hour. Can be a blown thermal fuse, bad heater, or the control board failing to trigger the defrost cycle entirely.
Board Often Cause
Er CF
Condenser Fan Motor Defective
Condenser fan at the back of the unit is not running or not reporting to the board. After confirming the fan motor is not physically blocked, the main control board is frequently the underlying fault.
Board Often Cause
Er CO
Communication Error (Main Board / Display)
Internal communication failure between the main control board and the display board. This is a direct board failure — if a power cycle does not clear it, one of the boards needs to be replaced.
Board Often Cause
Er FS / F dS / r dS
Freezer / Defrost Sensor Error
Thermistor or wiring fault in the freezer or defrost sensor circuit. Usually the sensor itself, but the main control board manages all sensor inputs — a board failure can produce false sensor codes.
Board May Be Involved
Er rS
Refrigerator Sensor Error
Refrigerator compartment thermistor is reading out of range. Check the thermistor and wiring first — if sensors test properly, the control board's sensor input circuitry may have failed.
Board May Be Involved
Er IF
Ice Compartment Fan Error
Ice maker fan motor failure or obstruction. Clear frost first; if the fan runs freely but the code returns, the board may not be sending the right signal to the ice maker fan circuit.
Board May Be Involved

Note: Error codes may display differently by model — some LG units prefix with "E" instead of "Er". Always search by your part number, not the error code alone.

Symptoms a Replacement Board Can Fix

Here is what the control board manages — and what breaks when it fails.
🌡
Refrigerator not cooling or freezer not freezing
📟
Er FF, Er rF, Er dH, Er CO or other error codes displayed
🖥
Control panel is unresponsive or display has gone blank
🔇
Compressor not starting — unit completely dead
🧰
Ice maker stopped working without explanation
❄
Excessive frost or ice buildup on rear evaporator coils
🔁
Fridge defrosts manually but error codes return within days
🔈
Fan running constantly or not running at all

Finding Your LG EBR or EBX Part Number

The part number on the sticker on your current control board is the only reliable way to confirm fitment — not your model number. LG uses dozens of board variants across similar-looking models. If you cannot access it or are not sure, send us a message before you order and we will confirm the right board for you.

LG Control Board FAQs

Real questions. Answered straight.
My LG shows Er rF — does that always mean the control board is bad?

Not always — but it is one of the most common causes. The Er rF code means the refrigerator fan motor is not responding correctly. The first thing to check is frost buildup around the fan blades (unplug the fridge and let it defrost for 8+ hours). If defrosting clears the error but it comes back within 1–2 weeks, the control board is almost certainly failing to run the defrost cycle properly — a board issue, not a fan issue.

If the fan blades spin freely when the fridge is unplugged but the error returns immediately when powered back on, the board's fan output circuit has likely failed. That is what our EcoSmart replacement board fixes.

LG says I need to call a technician. Can I replace the control board myself?

Many customers replace LG control boards themselves — it is typically a straightforward swap. The board is usually located at the back of the refrigerator. You unplug the harness connectors, remove a few screws, swap the board, and reconnect. Most people without any appliance repair experience complete it in 30–45 minutes using a YouTube video for their specific model.

The key is matching the correct board by part number. If you have the part number and a screwdriver, you can likely handle this yourself. We are happy to walk you through it if you have questions.

I replaced the board once before and the problem came back. Why?

There are a few reasons this happens with LG refrigerators specifically. Some LG models have a known defrost system issue where the root cause is a combination of the board and a defrost sensor or heater that was already damaged. Replacing just the board fixed the error temporarily, but the secondary component continued degrading and overloaded the new board.

LG has also released updated board revisions for models that had design issues. If you tell us your model and part number, we can let you know what we have in stock and whether an updated revision is available.

What does your 6-month warranty cover on an LG board?

If the board fails due to a defect within 6 months, we repair or replace it — no runaround. What is not covered: incorrect installation, power surge damage, or physical damage. If you install the board and it does not fix your original problem because a different component was the actual cause, that is not a defect — but we will help you troubleshoot and find the right part.

My LG refrigerator shows "OF F" on the display — is that a board problem?

No — "OF F" is Demo Mode (also called Display Mode or Showroom Mode). It disables all cooling to save energy when the unit is on display in a store. If this activates accidentally, the fridge will show normal temperatures on the display but will not actually cool. To disable: open either refrigerator door, then press and hold the REFRIGERATOR and ICE PLUS buttons simultaneously for 5 seconds until you hear a beep.

If Demo Mode keeps re-activating on its own, that can indicate a control board fault.
