How to Fix / Troubleshooting
Safety First: Disconnect power before accessing the lock mechanism.
- Check door closure: Ensure the door is fully closed and not obstructed by racks or pans.
- Listen for lock motor: When starting self-clean (before disconnecting power), listen for the lock motor. No sound suggests a motor or control issue.
- Access lock assembly: Remove the top or rear panel to reach the door lock motor assembly. Inspect for broken linkages or bent latch parts.
- Test motor and switches: With power off, test the lock motor for continuity and the lock position switches for proper operation. Replace the assembly if defective.
- Control board: If the lock assembly is good, the electronic oven control board may not be sending power to the lock motor and may need replacement.
