If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Critical safety warning: The high-voltage system in a microwave (inverter, transformer, capacitor, magnetron) can store and generate lethal voltages. Do not attempt high-voltage repairs unless you are trained and equipped. In most cases, contact a professional technician.
User-level checks:
- Unplug the microwave for 10–15 minutes and then plug back in to see if H97 clears temporarily.
- If the error returns immediately when trying to cook, discontinue use.
Likely repair:
- On inverter-based Maytag models, H97 typically indicates a failure of the inverter power board or magnetron.
- A technician will test the magnetron and inverter and replace the defective component(s).
Note: Because of the danger involved, high-voltage component replacement is not recommended as a DIY repair.
