Common Symptoms

  • Microwave does not heat
  • Microwave does not operate
  • Microwave shuts off after running briefly
  • Exhaust or cooling fan may not operate in some applications
  • Burning smell may be present if overheating caused the cut-off to open

Check Before Replacing

  • Disconnect power before inspection; microwave high-voltage capacitors can retain a lethal charge even when unplugged.
  • Check for blocked or restricted ventilation and signs of overheating around the thermostat area without removing energized covers.
  • After the appliance is safely de-energized and the capacitor is properly discharged by a qualified technician, test the component for continuity with a multimeter.
  • If the cut-off is open, investigate airflow, fan operation, wiring, and other overheating causes before replacing it; an open cut-off alone does not identify the root cause.

Pro Tip

Because this is an overheat-protection device, verify that ventilation and cooling-fan operation are not contributing to the failure before installing the replacement.
