Possible Causes
Failed door lock motor assembly, Broken or jammed lock latch, Faulty door lock switch, Wiring issue between lock and control board
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker. Do not force the door open if the oven is still hot.
- Allow to cool: If the error occurred during self-clean, wait until the oven is completely cool; some models will unlock automatically once temperature drops.
- Access lock assembly: Remove the top panel or rear panel (depending on model) to reach the door lock motor and latch mechanism.
- Inspect mechanism: Check for bent linkage, broken plastic parts, or obstructions. Manually move the latch to verify it is not seized.
- Test lock motor and switches: Use a multimeter to check continuity of the lock motor and associated micro-switches. Replace the door lock assembly if the motor is open or switches do not change state when actuated.
- Wiring check: Inspect the harness from the lock to the control board for damage or loose connectors.
