How to Fix / Troubleshooting
Safety first: Turn off power and let the oven cool completely.
- Attempt power reset: After cool-down, restore power and see if the lock releases automatically.
- Manual unlock: Access the latch from the top or rear and manually move it to unlock the door.
- Inspect and test lock assembly: Check for mechanical binding and test motor and switch with a multimeter. Replace the assembly if defective.
- Check control output: If the lock assembly is good, the EOC may not be sending the unlock signal and will need replacement.
