Possible Causes

Open main oven element, failed oven thermostat or sensor, open thermal cut-out in oven circuit, selector switch not routing power to oven elements

How to Fix / Troubleshooting

Safety first: Isolate the oven from mains power.

  • Confirm modes: Test fan oven, conventional, and lower heat modes. Note which ones fail.
  • Test main oven element: Access and measure resistance of the main bake element. Replace if open.
  • Check oven thermostat/sensor: Test for continuity or correct resistance. Replace if faulty.
  • Inspect thermal cut-out: Locate any cut-out specific to the main oven and test for continuity.
  • Selector switch: If the grill works but oven modes do not, the selector contacts for oven positions may be burnt. Replace the selector switch.
