Possible Causes
Open-circuit main oven element, Faulty selector switch, Failed main relay on control board, Tripped safety thermostat
How to Fix / Troubleshooting
Safety first: Isolate the oven from mains power before removing covers or accessing wiring.
Step-by-step checks:
- 1. Confirm symptom: Test conventional, fan, and grill modes. If none produce heat, the fault is common to all heating circuits.
- 2. Check safety thermostat: Locate the safety thermostat on top of the cavity. Reset if it has a button; test continuity. Replace if open-circuit and non-resettable.
- 3. Inspect selector switch (analogue models): Remove the control panel and check the function selector switch for burnt contacts or loose terminals. Replace if damaged.
- 4. Test elements: Measure resistance of each heating element. If all are intact, suspect the main relay or PCB.
- 5. Replace control board: If the board is not sending power to any element despite correct inputs, replace the main control board.
Warning: Do not bridge safety devices or relays to force heating; this is a fire and shock hazard.
