LG Refrigerator Error Code C

The C code on an LG refrigerator indicates a Cooling FAN BLDC Motor Failure. It appears when the refrigerator's control board (MICOM) does not detect a feedback signal from the evaporator fan motor for 65 seconds or longer. The fault can be caused by a stuck fan blade, disconnected wiring, or a failed drive IC or transistor in the motor circuit. Without a functioning evaporator fan, cold air cannot circulate through the compartments properly.

It is not advisable to continue using the refrigerator normally while the C error is active. A non-functioning evaporator fan means cold air is not being circulated, so the refrigerator and freezer compartments may not maintain safe food storage temperatures. Perishable food can spoil quickly under these conditions. The issue should be diagnosed and repaired promptly to prevent food loss.

A reset may temporarily clear the C error code from the display, but it will return if the underlying hardware problem is not corrected. Because the code triggers after 65 seconds of missing fan feedback, the MICOM will detect the fault again once the refrigerator resumes normal operation without a functioning fan. A reset is useful for confirming whether the fault is intermittent, but it is not a fix. The fan motor, wiring, and drive circuit must be inspected and repaired to permanently resolve the error.

Some causes of the C error are DIY-friendly. If the fan is blocked by ice, allowing the refrigerator to defrost completely may resolve the issue without any parts. Checking and reseating loose wire connectors at the fan motor is also within reach for a careful homeowner. However, replacing the fan motor or diagnosing a failed drive IC on the control board typically requires technical experience and proper tools, so those repairs are best handled by a qualified technician.

Repair costs vary depending on the root cause. If only a wiring harness reconnection or a defrost cycle is needed, costs may be limited to a service call fee, typically in the range of $75 to $150. Replacing the evaporator fan motor generally adds $100 to $250 in parts and labor combined. If the main control board requires replacement due to a failed drive IC or transistor, total repair costs can range from $200 to $450 or more depending on the specific model and labor rates in your area.
