LG Refrigerator Error Code C-FAN ERROR

The C-FAN ERROR means the main control board has detected a problem with the condenser fan motor circuit. This can be caused by a contact failure on the feedback signal line, a broken or missing motor wire, or a defective fan motor. The condenser fan is responsible for cooling the condenser coils, so this error needs prompt attention to prevent cooling performance issues.

A power cycle or reset may temporarily clear the error code, but if the underlying cause is not repaired, the code will return once the refrigerator attempts to operate the condenser fan again. Resetting is useful for confirming whether the fault is intermittent, but it is not a permanent fix for a wiring fault or a failed motor.

If the problem is simply a loose connector or minor wiring issue, the repair cost may be minimal, primarily covering a service call fee in the range of $75 to $150. If the condenser fan motor needs replacement, parts typically cost between $30 and $100 depending on the model, plus labor. If the main PCB is at fault, that repair can run from $150 to $400 or more for parts and labor combined.

Start by checking the voltage at Main PCB connector CN 74 between pins 4 and 7. A reading between 7V and 12V means the board is supplying power correctly, so the fault is likely in the wiring harness or the motor itself. Inspect all connectors and wiring for damage, corrosion, or loose pins, and check for any physical obstruction blocking the fan blade. If the wiring checks out and voltage is correct, the condenser fan motor likely needs to be replaced.

The error itself is not a safety hazard, but ignoring it can lead to the refrigerator losing its ability to cool properly, which may cause food spoilage. Without a functioning condenser fan, heat buildup can also stress the compressor over time. It is best to diagnose and resolve the issue promptly rather than allowing the refrigerator to run in a faulted state.
