GE Range Error Code F1x (door lock)

The F1x door lock code means the door lock system lost its home position signal while the oven was in use. The control board monitors a cam switch on the lock motor to confirm its position, and when that signal becomes untrue during cooking or a self-clean cycle, the fault is triggered. The control will attempt to jog the motor back into position automatically. If it cannot, the fault remains active until the underlying issue is resolved.

It is not recommended to continue using the range with an active F1x fault. The door lock system is a safety component, particularly during self-clean cycles where the oven reaches very high temperatures. A lock that cannot confirm its position may not secure the door reliably, creating a potential safety hazard.

Repair costs vary depending on which component has failed. A replacement door lock motor assembly typically ranges from around 50 to 150 dollars in parts. If the RPSM control board needs replacement, costs can run from 150 to 350 dollars or more for the part alone. Adding professional labor will increase the total, so getting a diagnostic estimate before authorizing repairs is advisable.

Some steps are within reach for a knowledgeable DIYer. You can inspect the wiring harness at connector J16 on the RPSM for loose connections or visible damage, and you can check whether the cooling fan is running. However, testing the cam switch requires a multimeter and some disassembly. Replacing the lock motor or RPSM is more involved and may be better handled by a qualified technician.

Resetting the range by cutting power at the breaker or unplugging it may temporarily clear the code, but the fault will return if the underlying problem is not fixed. The control will detect the missing or incorrect cam switch signal again as soon as the door lock system is activated. A reset is useful for confirming whether the fault is intermittent, but it is not a repair.
