GE Refrigerator Error Code F51

F51 means the refrigerator's control system detected that cooling was needed but the compressor stayed off for 6 consecutive hours. The appliance was calling for cooling but the compressor never responded. This points to a problem with the compressor itself, its starting components, or the control circuitry that activates it.

No, it is not safe to rely on the refrigerator for food storage when F51 is active. Because the compressor is not running, the unit is not cooling, and food temperatures will rise into the unsafe zone within a few hours. Transfer perishables to a working cooler or alternative refrigerator until the fault is resolved.

Resetting the refrigerator by unplugging it for several minutes may clear the code temporarily, but if the underlying problem is not fixed, the fault will return once the control system again detects 6 hours of compressor inactivity during a cooling demand. A reset should only be used as part of the diagnostic process, not as a permanent fix.

Some causes are DIY-friendly, such as replacing the start relay, which is an inexpensive part that clips onto the compressor and requires no special tools. However, diagnosing whether the issue is the relay, overload protector, control board, or the compressor itself requires electrical testing with a multimeter. If the compressor has failed, that repair involves the sealed refrigerant system and requires a certified technician.

Repair costs vary depending on the failed component. A start relay is generally an inexpensive fix, typically in the range of $20 to $60 for the part alone. A control board replacement can cost $150 to $400 or more in parts. A compressor replacement is the most expensive outcome, often ranging from $400 to $700 or higher including labor, and may make older units not worth repairing.
