GE Refrigerator Error Code F105

F105 means the condenser fan motor has been running at 100% power for 2 minutes without reaching its target RPM. The control board detects this failure and logs the fault to alert you that the fan is not operating correctly. This fan is critical for removing heat from the condenser coils, and without it working properly, the refrigerator's cooling performance will decline.

Continuing to run the refrigerator with an active F105 error is not recommended. A condenser fan that cannot reach target RPM will allow heat to build up around the compressor, which can shorten the compressor's lifespan or cause it to shut down entirely. Food safety may also be at risk if cooling performance drops significantly.

Repair costs depend on the root cause. Cleaning the fan and condenser area yourself costs little to nothing. A replacement condenser fan motor typically ranges from $40 to $120 for the part, with labor adding $80 to $200 depending on your area. A control board replacement, if needed, can range from $150 to $400 or more for parts and labor combined.

Some causes of F105 are DIY-friendly, such as clearing debris from the fan blade or cleaning the condenser coils. However, replacing the fan motor or diagnosing a control board issue typically requires experience with appliance wiring and component testing. If basic cleaning does not resolve the fault, a qualified technician should perform further diagnosis.

A reset may temporarily clear the F105 code, but if the underlying problem with the condenser fan is not fixed, the error will return quickly. The control board triggers F105 based on real-time fan speed monitoring, so the fault will reappear as soon as the motor again fails to reach its target RPM.
