Possible Causes

Failed inverter power board, Shorted magnetron drawing excessive current, Loose connections between inverter and control board, Overcurrent protection triggered

How to Fix / Troubleshooting

Danger: Inverter-based microwaves contain high-frequency high-voltage circuits that are extremely dangerous. Only trained technicians should service the inverter or magnetron.

User checks:

  • 1. Power reset: Unplug the microwave for 10–15 minutes to reset the inverter protection. Plug back in and test with a short heating cycle.
  • 2. Ventilation: Ensure vents are clear to prevent overheating of the inverter module.

Technician checks:

  • Inspect the inverter board for burn marks or bulging components.
  • Check the magnetron for shorts and verify correct connections.
  • Measure supply voltages to the inverter from the main control board.

Resolution: Replace the inverter board and/or magnetron with OEM-compatible IKEA parts. In many cases, both are replaced together to ensure reliability.
