How to Fix / Troubleshooting
Safety first: Confirm the oven cavity is cool before attempting to open the door. Turn off power at the breaker.
- Wait additional time: Some locks release only after the sensor confirms a safe temperature. Wait at least 30–60 minutes after the cycle ends.
- Manual release: Remove the top or rear panel to access the lock assembly. Use a suitable tool to gently move the latch to the unlocked position.
- Inspect lock assembly: Check for heat damage or binding. Replace the door lock motor assembly if it does not move freely.
- Avoid self-clean until repaired: Do not run self-clean again until the lock mechanism is replaced or adjusted.
