How to Fix / Troubleshooting
Critical safety warning: High-voltage components inside the microwave can be lethal. Do not attempt internal repairs unless you are a trained technician.
User-level checks:
- Verify that you are using microwave-safe containers and that you are not using metal or foil that could interfere with heating.
- Try heating a cup of water for 1–2 minutes. If it remains cold, discontinue use.
Technician-level outline:
- Unplug the unit and safely discharge the high-voltage capacitor.
- Inspect the magnetron, high-voltage diode, capacitor, and transformer or inverter for visible damage.
- Test each component according to Balay service procedures and replace the defective part.
Because of the risk of electric shock and radiation leakage if incorrectly repaired, this fault should be handled by an authorized Balay service technician.
