Possible Causes
Tripped thermal cut‑out, Open bake and grill elements, Faulty main relay on control board, Loose wiring at terminal block
How to Fix / Troubleshooting
Safety first: Disconnect the range from mains before removing panels. Some components may still be hot.
- Check circuit breaker: Ensure the cooker breaker has not tripped and that full supply voltage is present.
- Test different modes: Try bake, grill, and fan modes. If none heat, suspect a common supply issue.
- Inspect terminal block: A technician should check for loose or burned connections where the mains cable enters the range.
- Reset thermal cut‑out: Some models have a manual reset thermostat on the rear; press it once after cooling.
If there is still no heat, the control board or wiring harness likely needs professional diagnosis.
