How to Fix / Troubleshooting
Safety first: Turn off power and ensure the oven cavity is cool before attempting to release the door.
- Power reset: Turn the breaker OFF for 5 minutes, then ON. Sometimes the control will retry the unlock sequence.
- Manual release: Access the lock mechanism from the top or rear and manually move the latch to the unlocked position using a suitable tool. Do not force the door from the front.
- Inspect lock assembly: Once open, remove the lock assembly and check for worn gears, melted plastic, or seized components. Replace the assembly if damaged.
- Check switch feedback: Test the lock position switch with a multimeter. If it does not change state between locked and unlocked, replace the lock assembly.
