Possible Causes
Open grill heating element, Failed convection heater, Faulty heater thermostat, Burnt wiring to heater assembly
How to Fix / Troubleshooting
Safety first: Unplug the microwave and allow any heaters to cool completely.
- Visual inspection of heaters: Remove the top or rear cover as required. Inspect the grill element and convection heater for breaks, burn marks, or deformation.
- Check wiring: Follow the wires from the control board to the heater terminals. Look for burnt connectors or melted insulation. Repair or replace damaged wiring.
- Test heater continuity: Disconnect the heater terminals and measure resistance with a multimeter. An open circuit indicates a failed element that must be replaced.
- Check heater thermostat: Many Telefunken models have a thermostat near the grill. Test for continuity; replace if open and not self-resetting.
- Reassemble and test: After replacing faulty parts, reassemble and test grill/convection modes to confirm E07 is cleared.
