GE Range Error Code FC

FC on a GE range means the control board has detected a problem with the door lock circuit. This includes the wiring between the control board and the door lock assembly, as well as the door lock switches themselves. The board is not receiving the expected electrical signal to confirm proper lock operation, which typically surfaces during or when attempting a self-clean cycle.

Start by unplugging the range and visually inspecting the wiring harness that runs from the control board to the door lock assembly, looking for any pinched, burned, or chafed wires. Next, test the door lock switches with a multimeter to check for proper continuity and resistance. If the wiring is intact and switches test good, the door lock motor assembly or the control board may need replacement. Reconnecting any loose connectors or replacing damaged wiring does not require professional service, but control board replacement on GE ranges can be more involved and warrants a qualified technician if you are not comfortable working with appliance electronics.

Unplug the range from power before beginning any testing. Locate the door lock assembly and disconnect the wiring harness connector. Set your multimeter to the resistance (ohms) setting and probe each switch terminal pair individually. A properly functioning closed switch should read near zero ohms, and an open switch should read infinite or OL. Consult your model's wiring diagram, available in the tech sheet typically taped inside the oven door or storage drawer, for the exact terminal locations and expected resistance values for each switch position.

Standard baking and surface cooking are generally unaffected by the FC code because the door lock circuit is only active during the self-clean cycle. However, you will not be able to run a self-clean cycle until the fault is resolved, and some GE models may restrict oven operation entirely when this code is active. Check whether your oven heats normally, and address the underlying wiring or switch issue before attempting another self-clean cycle.

If the fix is simply repairing or rerouting a pinched wire, cost is minimal, just your time and possibly a small amount of wire or a connector. A replacement door lock switch or lock motor assembly typically runs between $30 and $90 for the part. A new electronic control board for a GE range usually costs between $150 and $350 depending on the model. Adding professional labor, expect a total repair bill anywhere from $150 for a simple wiring fix to over $400 for a control board replacement.
