How to Fix / Troubleshooting
Safety: Ensure the oven is empty and racks are removed before attempting self-clean.
- Verify door lock: Confirm that the door closes firmly. Listen for the lock motor when starting self-clean. If no sound, check the lock assembly.
- Check error history: If the oven has recently overheated or shown temperature-related errors, the control may block self-clean. Disconnect power for 10 minutes to reset.
- Inspect high-limit devices: Test thermal fuses and high-limit thermostats for continuity. Replace any open devices.
- Review user steps: Follow the exact self-clean procedure in the Sub-Zero manual, including setting duration and confirming start.
