Possible Causes
Mechanical thermostat contacts welded closed (on rotary-thermostat models), Shorted temperature sensor, Faulty control board not cycling element, Miscalibrated thermostat knob
How to Fix / Troubleshooting
Safety: If the oven is overheating, switch off power immediately and do not use until repaired.
- Check thermostat setting: Confirm the temperature knob markings align with the pointer. A slipped knob can give false settings.
- Test sensor or thermostat: On electronic models, measure the NTC sensor resistance; replace if shorted. On mechanical models, test the thermostat contacts for continuity; they should open when the shaft is turned to off.
- Observe cycling: With a thermometer inside, run the oven and see if the element cycles off when temperature is reached. If it stays on continuously, the thermostat or control board is faulty.
- Replace faulty control: Replace the thermostat (mechanical) or sensor/PCB (electronic) as indicated by tests.
