GE Refrigerator Error Code F201

The F201 error code on a GE refrigerator indicates that the fresh food compartment defrost cycle reached its maximum allowed run time without terminating normally. Under normal operation, the defrost cycle is ended by a temperature-sensing component, typically the evaporator thermistor or a termination thermostat, once the evaporator coil has cleared its frost accumulation. When the system instead runs until the timer forces a cutoff, the control board logs F201 to flag that something prevented a proper temperature-based termination.

The three primary components involved are the fresh food defrost heater, the overtemperature thermostat, and the evaporator thermistor. If the heater is weak or has failed open, it may not generate enough heat to raise the evaporator temperature to the termination setpoint within the allotted time. A defective overtemperature thermostat that has opened prematurely or fails to close can interrupt the heating circuit early, also resulting in a timeout. Alternatively, a faulty evaporator thermistor reporting incorrect temperature readings can cause the control board to never receive the signal needed to terminate the cycle on time.

Beyond component failures, heavy frost accumulation from a door seal leak or a separate sealed system issue can extend the time required to complete a defrost cycle, pushing it past the maximum threshold. Diagnosing F201 involves checking heater continuity, verifying the overtemperature thermostat closes at the correct temperature, and measuring thermistor resistance against the expected values for a given temperature to confirm accurate reporting to the control board.
