LG Refrigerator Error Code ER FF – Freezer Fan Not Working

If your LG refrigerator is flashing the ER FF error code, it means the unit has detected a Freezer Fan failure. The fan is responsible for circulating cold air throughout the freezer and refrigerator compartments. When it fails, your fridge can’t maintain proper temperature.

What Causes the ER FF Error?

Common reasons this code appears include:

• A frozen or iced-over freezer fan motor
• Faulty fan motor or wiring
• Blocked air vents preventing airflow
• Defective main control board (in rare cases)

How to Fix LG ER FF Error

1. Unplug the Refrigerator: Always disconnect power before doing any inspection or repairs.
2. Check for Ice Build-Up: Remove freezer panel and inspect the fan blades. If the motor or fan is frozen over, defrost it using a hairdryer or allow it to thaw completely with the power off.
3. Test the Fan Motor: Once thawed, spin the fan by hand. If it doesn’t move freely or hums loudly, the motor may be burned out and needs replacing.
4. Inspect the Wiring: Check for loose or corroded fan connectors. Re-seat them securely.
5. Replace the Fan or Control Board: If the wiring is intact and the fan still doesn't work, replace the freezer evaporator fan motor. If the motor tests good, the issue could be a defective control board.
