How to Fix / Troubleshooting
Safety first: Turn off power immediately if overheating occurs. Allow the oven to cool completely.
- Check sensor: Test the oven temperature sensor resistance at room temperature and compare to specification. Replace if significantly low or unstable.
- Inspect control relays: Remove the control board and inspect for welded or burnt heating relays. Replace the control board if relays are stuck closed.
- Verify wiring: Compare element wiring to the wiring diagram. Correct any miswiring that could bypass control.
- Test high-limit thermostat: Confirm the high-limit thermostat opens at its rated temperature (requires specialized equipment). If it never opens or is bypassed, replace it.
