Possible Causes
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.
