How to Fix / Troubleshooting
Safety first: Unplug the microwave. Inverter circuits operate at high voltage and high frequency.
- Basic reset: Leave the unit unplugged for 15–20 minutes to allow the inverter to discharge and reset. Plug in and test again.
- Inspect grounding: Ensure the inverter module is firmly screwed to the chassis and that all ground wires are securely attached.
- Check for visible damage: Look for burnt components on the inverter board or arcing marks near the magnetron terminals.
- Professional service recommended: Inverter diagnosis and replacement should be performed by an authorized Telefunken technician due to the complexity and danger.
