How to Fix / Troubleshooting

Safety warning: Repeatedly resetting a tripping breaker can be dangerous. Do not continue to use the microwave until the fault is found.

User checks:

  • Try a different outlet on a separate circuit to rule out house wiring issues.
  • If the breaker trips only when this microwave is used, unplug it and do not use again until repaired.

Professional diagnosis: A technician will test the mains filter, high-voltage capacitor, diode, magnetron, and transformer for shorts. These tests involve high voltage and should not be attempted by untrained persons.
