Possible Causes
Failed door lock motor, Faulty lock position switch, Jammed latch mechanism, Wiring issue between lock and control
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before attempting to access the lock mechanism.
- Wait for cool-down: If the error occurred during self-clean, allow the oven to cool completely before attempting to unlock.
- Manual unlock: Use the manual release (if provided on your Dacor model) to open the door. This is often accessible from the top or front panel.
- Inspect lock assembly: Remove the top/front panel to view the lock motor and latch. Check for broken parts or obstructions.
- Test motor and switches: With power off, test the lock motor and limit switches for continuity. Replace the door lock assembly if components are defective.
- Check harness: Ensure wiring between the lock and control board is intact and connectors are secure.
Warning: Do not force the door open; this can damage the hinges and glass.
