How to Fix / Troubleshooting
Safety Warning: Do not operate the microwave with covers removed. Internal components can carry lethal voltages.
User checks:
- Allow cooling: If the microwave has been used heavily, unplug it and let it cool for 30–60 minutes, then test again.
- Clear vents: Inspect the side, rear, and top vents. Remove dust buildup and ensure there is adequate clearance around the unit for airflow.
- Listen for fan operation: Start a short cook cycle and listen for the internal cooling fan. If you do not hear it, the fan may have failed and requires service.
If H96 persists:
- The inverter board or cooling fan motor may be defective.
- Discontinue use and schedule service with a qualified technician to prevent further damage.
