How to Fix / Troubleshooting
Safety First: Unplug the microwave before internal inspection.
- Check ventilation: Ensure there is adequate clearance around the microwave per JennAir installation instructions. Clean grease filters and exterior vents.
- Observe door: Watch the door during operation. If it vibrates or shifts, a loose latch or switch may be interrupting power.
- Inspect door switches: Access and test the door switches for intermittent operation by gently wiggling the switch bracket while checking continuity.
- Cooling fan: Verify the cooling fan motor runs whenever the magnetron is on. Replace if not operating.
- Thermostats: Test the magnetron thermostat and cavity thermostat for proper continuity. Replace if they open prematurely or do not reset.
