How to Fix / Troubleshooting
Safety: Turn off power and allow the oven to cool completely. Components near the high-limit thermostat can be very hot.
Steps:
- Locate the high-limit thermostat (often on the rear of the oven or top of the cavity). It is usually a small round or rectangular device with two terminals.
- Test for continuity across the thermostat. If it's open, check whether it has a manual reset button; press to reset if present.
- If it does not reset or opens again quickly, investigate causes of overheating, such as blocked vents, a failed cooling fan, or improper installation clearance.
- Replace the high-limit thermostat if it does not reset or tests defective.
- Verify cooling fan operation and clear all ventilation paths before returning the oven to service.
