Possible Causes
Open high-limit thermostat, Blown thermal fuse, Overheating due to blocked vents or failed cooling fan, Loose wiring to high-limit device
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker and allow the oven to cool completely before servicing.
- Inspect ventilation: Ensure that the oven's front and rear vents are not blocked by cabinetry, foil, or other obstructions.
- Check cooling fan: Confirm that the internal cooling fan runs during operation. If not, diagnose the fan motor, thermostat, and control relay.
- Access high-limit/thermal fuse: Remove the rear or top panel to locate the high-limit thermostat or thermal fuse (often mounted on the oven top or rear). Test for continuity with a multimeter. If open, it must be replaced.
- Investigate cause of trip: A blown fuse or open thermostat usually indicates overheating. Verify that the fan and airflow are correct before replacing the part.
Warning: Never bypass a thermal fuse or high-limit thermostat; they are critical safety devices.
