How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before inspection.
- Check ventilation: Ensure the oven has proper cabinet clearances and vents are not blocked.
- Inspect cooling fan: Confirm the cooling fan runs during cooking. Replace if intermittent or not running.
- Inspect wiring and terminal block: Look for loose or overheated connections that could open when hot.
- Test high-limit thermostat: Replace if it opens prematurely or shows signs of heat damage.
Warning: Do not continue using the oven until the cause of the shutdown is identified; repeated overheating can cause permanent damage.
