GE Range Error Code F5 E4

The F5 E4 error code on a GE range indicates a latch switch fault, meaning the control board is detecting an abnormal signal from the door latch switch assembly during a self-clean cycle or latch operation. The door latch system on a self-cleaning range consists of a latch motor that physically drives the lock mechanism and one or more latch switches that report the latch position back to the control board. When the board cannot confirm the correct switch state at the expected time in the latch sequence, it triggers F5 E4 and halts operation to prevent the oven from running an unlocked self-clean cycle.

The latch switch assembly is typically located at the top rear of the oven cavity behind the front console or at the door frame depending on the model. The switch provides a closed or open circuit signal to indicate whether the latch is fully engaged or fully retracted. Faults arise when the switch contacts fail mechanically, when the latch motor does not drive the mechanism far enough to actuate the switch, or when wiring between the switch and control board is damaged or corroded.

Diagnosing this fault requires entering the range diagnostics mode and pressing the CLEAN key to command the latch motor through a full cycle. This allows a technician to observe whether the latch motor runs, whether it completes its travel, and whether the switch changes state as expected. If the motor runs but the switch does not respond, the switch itself is the likely culprit. If the motor does not run at all, the fault may be upstream in the wiring harness or the control board output circuit.
