Possible Causes
Failed door lock motor, Misaligned or broken door lock latch, Faulty door lock position switch, Wiring fault between lock assembly and EOC
How to Fix / Troubleshooting
Safety: Ensure power is off before working on the door lock. The lock mechanism can move unexpectedly during powered tests.
Steps:
- Access the door lock assembly (typically from the top or rear of the oven). Remove the top panel or rear cover as needed.
- Inspect the lock motor and latch for obvious damage or binding. Manually move the latch to verify it can travel fully.
- Test the door lock motor for continuity and proper resistance. Replace if open or shorted.
- Check the door lock position switch(es) for continuity in locked and unlocked positions. Replace if they do not change state.
- Inspect wiring from the lock assembly to the EOC for breaks or loose connectors.
- If the lock assembly and wiring are good, the EOC lock driver circuit may be faulty and the control board should be replaced.
