How to Fix / Troubleshooting
Safety first: Turn off power at the breaker and allow the oven to cool completely.
- Wait for cooling: The door will not unlock until the oven cools below a safe temperature. Wait several hours if necessary.
- Manual release: Remove the rear top panel and manually move the lock arm to the unlock position to open the door.
- Inspect lock assembly: Check for binding, broken springs, or melted plastic. Replace the lock assembly if it does not move freely.
- Test unlock switch: Use a multimeter to verify the unlock switch changes state when the latch is in the unlocked position.
- Replace lock or control: Replace the door lock assembly if defective. If the lock is good but the control does not drive it, replace the main control board.
