How to Fix / Troubleshooting
Safety: Unplug the unit before any internal inspection.
- Observe door fit: Watch the door as the unit starts. If it vibrates or shifts, the latch may be marginal and causing switch dropout.
- Try gentle pressure: While running (if safe), gently press on the door. If the unit runs longer when pressure is applied, door switch alignment is suspect.
- Check vents and filters: Clean grease filters and ensure vents are not blocked to prevent overheating.
- Service door switches: Have a technician inspect and replace any worn door switches or adjust the latch bracket.
