Oven displays F9 or F9-0; door may not lock/unlock during self-clean, or oven may not start self-clean.

Safety First: Turn off power at the breaker. The door lock mechanism can move unexpectedly; keep fingers clear of moving parts.

• Check door movement: Ensure the oven door closes fully and is not misaligned or obstructed.
• Listen during lock attempt: Start a self-clean cycle briefly and listen for the lock motor. If you hear no motor sound, the lock motor or its power supply may be faulty.
• Access lock assembly: Remove the top or rear panel (depending on model) to access the door lock motor and latch assembly. Inspect for broken plastic parts, bent linkage, or obstructions.
• Test lock motor and switches: With power disconnected, check continuity of the lock motor and lock switches using a multimeter. Replace the door lock motor assembly if the motor is open or switches do not change state when actuated.
• Wiring and control: Inspect wiring from the EOC to the lock assembly. If lock assembly and wiring are good, replace the EOC.
