GE Range Error Code F92x

The F92x error code on a GE range indicates a conflict in the door lock system: both the Lock-Home switch and the Unlock-Home switch are reporting a closed state at the same time. These two switches are part of the cam-driven lock mechanism, typically referred to as the RPSM (Range Power Supply Module) door lock assembly. Under normal operation, only one of these switches should ever be closed at a given moment, since they track opposite positions of the lock motor cam. When both report closed simultaneously, the control board detects a physically impossible condition and triggers the F92x fault.

The most likely mechanical cause is a lock motor cam switch that has become stuck in the closed position. The cam rotates between the locked and unlocked positions, and if one of its switches fails to open as the cam moves, both switches will appear active at the same time. Another mechanical cause is insulation or wiring material that has become wrapped around the cam, physically preventing it from completing a full rotation and leaving a switch compressed when it should be released. These conditions prevent the oven door lock from functioning correctly and block entry into or exit from a self-clean cycle.

If the mechanical components appear intact and no cam or switch damage is found, the fault may originate in the RPSM Main Board itself, which processes the switch signals. A failed input circuit on the board can misread switch states, producing the same error even when the lock assembly is mechanically sound. Diagnosis should proceed by inspecting the cam and switches first before condemning the board.
