How to Fix / Troubleshooting
Safety first: Allow the oven to cool completely. Turn off power at the breaker before attempting manual release.
- Wait for cooling: The door will not unlock until the cavity cools below a safe temperature. Wait at least 1–2 hours after self-clean.
- Manual release: Remove the top panel and locate the door lock motor assembly. Manually move the lock lever to the unlock position to open the door.
- Inspect latch: Check for warped or damaged latch components. Replace the door lock motor and latch assembly if binding or burned.
- Test switches: Use a multimeter to verify the lock/unlock switches change state when the latch moves. Replace the assembly if switches fail.
