Possible Causes
How to Fix / Troubleshooting
Critical safety warning: The high-voltage section can be lethal. If you are not trained in microwave repair, do not attempt to service internal HV components.
User-level checks:
- 1. Confirm symptom: Heat a large mug of water on full power for 2–3 minutes. If the water remains cold, heating is not occurring.
- 2. Check door closure: Ensure the door closes firmly and there are no gaps. A faulty door switch can also prevent heating, even if the unit appears to run.
Technician-level checks:
- Test door interlock switches first, as they are safer to access.
- Discharge the high-voltage capacitor safely before testing the diode, capacitor, transformer, and magnetron.
- Replace the defective component(s) with Privileg-compatible parts.
Recommendation: For most users, a no-heat condition requires professional service or replacement of the microwave.
