Possible Causes
Shorted oven temperature sensor, Stuck bake relay on control board, Miswired heating elements, Failed high-limit thermostat
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker immediately if the oven overheats. Do not use the oven until repaired.
- Step 1 – Test sensor: With power off, remove the rear panel and test the oven temperature sensor resistance at room temperature. Replace if not within specification.
- Step 2 – Inspect wiring: Check for any signs of shorted wires or incorrect connections to the elements, especially after recent service.
- Step 3 – Control board: If the sensor is good, the bake relay on the control board may be stuck closed, continuously powering the element. Replace the control board.
- Step 4 – High-limit thermostat: Test the high-limit thermostat for proper operation; replace if it does not open at its rated temperature (technician test).
Warning: Overheating can damage cabinetry and pose a fire risk; do not ignore this symptom.
