Possible Causes
Blown high-limit thermostat, Open main oven element, Faulty function selector switch, Failed electronic control board
How to Fix / Troubleshooting
Safety first: Turn off power at the mains before any internal checks.
Steps:
- Confirm symptom: Try grill, fan oven, and conventional modes. If none heat, suspect a common supply issue.
- Check safety thermostat: Locate the high-limit thermostat on the oven casing and test for continuity. Replace if open.
- Test main elements: Measure resistance of the main oven and grill elements. Replace any that are open-circuit.
- Inspect selector switch: On knob models, check that the function selector is not burnt or mechanically broken.
- Control board: If power is not being sent to any element despite good components, replace the electronic control board.
