How to Fix / Troubleshooting
Critical safety warning: The high-voltage section can be lethal. Only qualified technicians should service magnetron, transformer, capacitor, and diode. Do not operate the microwave with the cover removed.
- Confirm no heat: Heat a cup of water for 1–2 minutes. If it remains cold while the timer counts down, the heating circuit has failed.
- Check power supply: Ensure the microwave is plugged directly into a properly grounded outlet (no long extension cords).
- Do not bypass safety devices: Never attempt to bypass door switches or thermal cut-outs to restore heating.
- Professional repair: A technician will test the magnetron, HV diode, capacitor, and transformer and replace the failed component with Gorenje-approved parts.
