GE Oven Error Code FC

The FC code on a GE oven indicates a fault related to one of several conditions: welded relay contacts that keep heating elements energized during an off command, an open thermal switch in the lock motor circuit caused by overheating, high resistance in the temperature sensor circuit, or electrical noise interference in the sensor wiring. The control uses this code to flag that the oven is not behaving as expected during normal operation or a self-clean cycle.

A reset by cutting power at the breaker for a few minutes may temporarily clear the FC code, but it will return if the underlying fault is still present. If the cause is welded relay contacts, a faulty thermal switch, or a damaged sensor connection, the code will reappear until the defective component is repaired or replaced. A reset is useful for ruling out a one-time electrical noise event, but it is not a fix.

Repair costs vary depending on the root cause. Replacing a relay board typically runs between $150 and $350 including parts and labor. A thermal switch replacement is generally less expensive, often in the $80 to $180 range. If the fault is limited to a loose or corroded sensor connection that can be serviced without new parts, a diagnostic and repair visit may cost between $75 and $150. Costs can be higher if multiple components are involved or if the control board itself requires replacement.

No, you should not use the oven until the FC code has been diagnosed and resolved. One possible cause is welded relay contacts, which can keep the heating elements on even when the oven is supposed to be off. This creates a potential overheating hazard and should be addressed before operating the appliance again.

Start by inspecting the relay contacts on the control or relay board for signs of welding or burning. Next, check the thermal switch in the lock motor circuit for continuity and inspect the cooling fan for stalling or obstruction. Then examine the sensor circuit wiring for poor crimps, deformed terminals, loose connections at the probe, or intermittent solder joints on the board. Finally, consider whether nearby wireless devices could be causing electrical noise interference, especially if the fault appears only occasionally.
