How to Fix / Troubleshooting
Safety: Verify the oven cavity is cool before attempting to open the door. Turn off power at the breaker.
- Wait for cooling: Some models delay unlocking until a safe temperature is reached. Allow several hours after self-clean.
- Power reset: Turn off the breaker for 5–10 minutes, then restore power and see if the lock cycles.
- Manual release (if provided): Consult the user or service manual for a manual door lock release. Some models have an access slot behind the control panel or under the cooktop.
- Access lock assembly: If no manual release, remove the top or rear panel to reach the lock motor. Manually move the latch to the unlocked position, then test the motor and switches. Replace the lock assembly if defective.
