Possible Causes
Open or shorted grill temperature sensor, Damaged wiring to grill sensor, Failed control board temperature input circuit
How to Fix / Troubleshooting
Safety first: Unplug the microwave. Internal components near the grill element can remain hot for some time.
User-level checks:
- Allow the unit to cool fully and then try again. Sometimes an overheated sensor will recover after cooling.
- Ensure the interior is clean and not covered with heavy grease, which can cause localized overheating.
If E7 persists:
- The grill/convection temperature sensor or its wiring is likely faulty.
- This requires removal of the outer cabinet and testing the sensor with a multimeter. Contact a technician to replace the sensor or repair wiring.
