Possible Causes
Failed inverter power board, Shorted magnetron, Loose high-voltage wiring between inverter and magnetron, Overheated or tripped thermal cutout on magnetron
How to Fix / Troubleshooting
Safety First: High-voltage microwave components are extremely dangerous. Unplug the unit and do not attempt to test the inverter or magnetron unless you are trained and have proper equipment.
- Reset and cool: Unplug the microwave for 15 minutes to allow internal thermal cutouts to reset, then test again.
- Listen during start: If the fan and turntable run but there is no typical humming from the high-voltage section, the inverter or magnetron may not be energizing.
- Visual inspection: With the cover removed (for professionals), inspect the inverter board for burn marks and check that all high-voltage connectors are firmly seated.
- Professional service: H97 almost always requires inverter or magnetron replacement. Due to lethal voltages, contact an authorized Amana service technician for diagnosis and repair.
