How to Fix / Troubleshooting

Safety Warning: Inverter-based microwave repairs involve lethal voltages. Do not attempt to service the inverter or magnetron yourself.

User steps:

  • 1. Reset power: Unplug the microwave for 10 minutes, then plug back in and test. If H97 reappears, internal components are likely damaged.
  • 2. Discontinue use: Do not continue trying to run the microwave, as this can further damage the inverter or magnetron.

H97 generally requires professional diagnosis. A technician will test the magnetron and inverter board and replace the defective component with an RCA-compatible part.
