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 section of a microwave is extremely dangerous. Do not attempt to service the magnetron, transformer, capacitor, or diode unless you are trained and know how to safely discharge the capacitor.
User-level checks:
- Verify that you are using microwave-safe cookware and not metal or dishes with metallic trim.
- Try heating a cup of water for 1–2 minutes. If it remains cold, the unit is not producing microwave energy.
- Unplug the microwave and discontinue use until inspected by a professional.
Technician-level repair (for reference): Test and replace the magnetron, high-voltage diode, capacitor, or transformer as needed using Hamilton Beach-compatible parts.
