GE Range Error Code F2x (door lock)

The F2x door lock error code on a GE range indicates that the Door Lock or Lock Home signal became untrue during a self-clean cycle. This means the control board received confirmation that the door was locked at the start of the clean cycle, but then lost that confirmation signal before the cycle completed. The door lock system uses a motorized cam mechanism with an associated switch to verify latch position. When the cam rotates to the locked position, a switch closes to send the Lock Home signal to the control board. If that signal drops out mid-cycle, the control registers the fault.

The range control module (RPSM) monitors the lock signal through connector J16. When an F2x fault is triggered, the control will attempt to recover by opening and closing the relay multiple times in an effort to jog the lock motor back into position. This cycling behavior is by design and does not indicate a separate electrical fault. If the motor cam switch is loose or intermittently failing, these jog attempts may or may not restore the signal. A wiring harness issue between the lock motor assembly and the RPSM J16 connector, such as a broken wire or loose terminal, can also cause the signal to drop.

An additional cause is a tripped Fuse Auto Disconnect (FAD), which is a thermal safety device tied to the cooling fan circuit. If the cooling fan fails during the high-heat clean cycle, the FAD can trip to protect internal components. When the FAD trips, it disrupts power or signal continuity in a way that causes the lock feedback to read as untrue. Checking the cooling fan for proper operation and verifying the FAD has not tripped should be part of any complete diagnostic for this code.
