How to Fix / Troubleshooting

Critical safety warning: Inverter-based microwaves operate at very high voltages and frequencies. The inverter board and magnetron are not user-serviceable. Risk of severe electric shock is high even when unplugged.

User-level actions:

  • 1. Power reset: Unplug the microwave for 10–15 minutes to reset the inverter and control board. Plug back in and test.
  • 2. Check for overloading: Ensure you are not using metal containers or oversized loads that could stress the inverter.
  • 3. Listen for abnormal sounds: If you hear loud buzzing or arcing when attempting to start, stop immediately.

Technician-only actions: Testing and replacing the inverter board or magnetron requires specialized training and tools. Do not attempt to access or repair the inverter module yourself.
