How to Fix / Troubleshooting
Safety: Unplug the appliance and allow it to cool completely. Internal metal parts and elements can be hot.
User checks:
- Ensure that no large items or accessories are touching the rear convection fan cover inside the cavity.
- Listen for the fan when starting a convection program. If it does not run at all, note this.
Reset:
- Unplug for 5–10 minutes, then plug back in and test a convection program at a moderate temperature.
Technician checks:
- Access the convection fan assembly and check for obstructions or seized bearings.
- Test the fan motor for continuity and insulation resistance; replace if faulty.
- Check the fan thermostat or thermal cut-out for continuity.
- Inspect wiring and control board outputs to the fan circuit.
Because the convection fan is critical for safe operation, E09 faults should be repaired by a professional.
