GE Refrigerator Error Code F300

The F300 error code on a GE refrigerator indicates that the compressor has been running continuously for five hours without cycling off. Under normal operation, a refrigerator compressor runs in cycles, turning on to cool the cabinet and shutting off once the target temperature is reached. When the compressor cannot reach that target and keeps running beyond the five-hour threshold, the control board logs F300 to flag the problem. Note that the initial compressor run at power-up is excluded from this timing, so the code only triggers during standard operation after the unit has been running.

This error points to a cooling system that is struggling to maintain temperature. The root cause can be refrigerant-side, airflow-related, or electrical. A refrigerant leak or low charge reduces the system's ability to absorb and transfer heat, forcing the compressor to run indefinitely trying to compensate. A failed condenser fan motor or heavily fouled condenser coils can also prevent adequate heat rejection, keeping the compressor working overtime. Door gasket failures or a door left ajar allow warm air infiltration that continuously adds heat load to the cabinet.

On the electrical and mechanical side, a weak or failing compressor that is unable to build adequate pressure will run without achieving proper cooling. A defective thermistor or temperature sensor could also cause the issue by feeding inaccurate readings to the control board, preventing a normal shut-off cycle. Because multiple failure points can produce this code, a systematic diagnostic approach starting with condenser coil condition and airflow, then moving to refrigerant charge and compressor performance, is the most efficient path to resolution.
