How to Fix / Troubleshooting
Safety: High-voltage components are dangerous. Limit yourself to external checks unless qualified.
User checks:
- Verify that the power level is set to 100% (or maximum) and not to a low setting or defrost mode.
- Test with a known load: heat 250 ml of water for 2 minutes; if barely warm, heating is inadequate.
- Ensure you are not using metal or thick ceramic containers that can slow heating.
If still no heat:
- The magnetron or high-voltage circuit is likely faulty and requires professional diagnosis and replacement.
