Oven door lock error; self-clean or pyrolytic cycle will not start, or oven reports door lock fault.

Safety: Ensure the oven is cool and disconnected from mains before working on the door lock. Do not force the door open during a lock cycle.

• 1. Check door closure: Make sure the door is fully closed and not obstructed by racks or trays.
• 2. Listen for lock motor: When starting a self-clean or lock-required mode, you should hear the lock motor operate. No sound suggests a motor or power issue.
• 3. Access lock assembly: Remove the top cover of the oven to access the door lock mechanism, typically located at the front top.
• 4. Inspect linkage: Check that the lock arm moves freely and is not bent or obstructed. Lubricate lightly with high-temperature-safe lubricant if stiff.
• 5. Test lock motor and switch: With power disconnected, measure resistance of the lock motor and the lock position switch. An open motor or switch requires replacement.
• 6. Wiring check: Inspect the harness from the lock assembly to the control board for breaks or loose connectors.
• 7. Replace lock assembly: If mechanical damage or electrical failure is found, replace the complete Panasonic door lock assembly.
