How to Fix / Troubleshooting
Safety first: Turn off power at the breaker and allow the oven to cool completely before attempting to unlock.
- Manual unlock: Access the lock mechanism from the top or rear panel and manually move the lock lever to unlock the door.
- Inspect lock assembly: Check for melted plastic, bent linkage, or seized motor. Replace the door lock assembly if damaged.
- Test switches: Use a multimeter to verify continuity of the lock and unlock switches when the mechanism is moved. Replace if faulty.
- Check wiring: Inspect the harness from the lock to the EOC for heat damage or loose connectors.
- Control board: If the lock assembly and wiring are good but F90 persists, replace the EOC.
