GE Range Error Code F1x (door lock)

The F1x door lock error on a GE range indicates that the Door Lock/Unlock Home signal became untrue while the oven was in a cooking or self-clean cycle. The home position signal is a feedback circuit that tells the Range Power Supply Module (RPSM) where the door lock cam is positioned. When the control expects this signal to remain in a confirmed state and instead detects an inconsistency, it triggers the F1x fault. The door lock assembly uses a cam switch to report the motor's home position, and any interruption in that signal during operation is treated as a locking system failure.

The RPSM responds to this fault by cycling the relay multiple times in an attempt to jog the lock motor back into its home position. This jogging behavior is by design and is part of the control's self-recovery routine, not a sign of additional damage. If the motor cannot be jogged back into position, the error persists. The three primary areas to investigate are the cam switch on the lock motor itself, the wiring harness that runs from the lock motor to connector J16 on the RPSM, and the Fuse/Appliance Device (FAD), which can trip if the cooling fan fails to maintain adequate airflow.

A tripped FAD is often overlooked but is a critical checkpoint. If the cooling fan is not operating correctly, thermal protection can activate and cut power to components in the lock circuit, producing conditions that mimic a mechanical lock failure. Always verify the cooling fan is spinning freely and delivering airflow before condemning the lock motor or harness.
