How to Fix / Troubleshooting

Safety: If the breaker trips, unplug the microwave and do not repeatedly reset the breaker.

  • Check circuit load: Ensure the microwave is on a dedicated circuit or not sharing with other high-power devices like kettles or heaters.
  • Inspect power cord and plug: Look for signs of overheating or burning.
  • Internal inspection: A technician should inspect the mains filter, wiring, and HV components for shorts or burn marks.

Because this involves mains and high voltage, internal diagnosis should be done by a professional.
