LG Range Error Code FC

The FC code on an LG range indicates a door latch error in which the control board is simultaneously receiving both the unlocked home and locked home signals from the door latch switches. This contradictory input triggers the fault. It most commonly occurs during or after a self-clean cycle when the latch mechanism fails to complete its travel to either position.

Basic cooktop burner operation may still be possible depending on the control board's response to the fault, but the self-clean function should not be attempted while this code is active. The FC error specifically involves the door latch, which is a safety-critical component during high-temperature cleaning cycles. It is best to address the fault before relying on the oven for baking or roasting as well.

Repair costs vary depending on which component has failed. Latch switch replacements are generally the least expensive fix, with parts typically ranging from around $15 to $50 and professional labor adding $75 to $150 or more. A full latch assembly or motor replacement will cost more, potentially ranging from $80 to $200 for parts alone. Control board replacement is the most expensive possibility, with parts ranging from $150 to $350 or higher depending on the model.

A power reset by unplugging the range or switching off the circuit breaker for a few minutes may temporarily clear the FC code, but it will likely return if the underlying latch issue is not resolved. The latch switches, cam position, and wiring should be inspected before attempting another self-clean cycle. Continuing to reset without repair risks repeated faults or a door that will not release.

Start by inspecting the door latch assembly, including the cam position and the condition of latch switches 1 and 2. Test each switch for proper continuity at the locked and unlocked positions. Check the wiring harness connected to the switches for any shorts, broken wires, or loose terminals. If a switch, the latch motor, or the cam is found to be defective, replacement of that component is required to resolve the fault.
