Possible Causes
How to Fix / Troubleshooting
Critical safety warning: The high-voltage section can be lethal. Do not attempt internal high-voltage (HV) repairs unless you are a trained technician.
User-level confirmation:
- Place a cup of water in the center of the turntable and run it on full power for 1–2 minutes.
- If the water remains cold while the timer counts down and everything appears normal, the heating components are likely faulty.
- Ensure the unit is not in demo mode (check the Fagor manual).
Next steps: Internal diagnosis involves testing the magnetron, transformer/inverter, capacitor, and diode. This should only be performed by a professional. Discontinue use until serviced.
