Thermador MAG error code
Magnetron or high-voltage circuit fault
No microwave heat points to the magnetron or high-voltage circuit — diagnosed and repaired by a technician, as it carries high voltage.
Likely causes
- Failed magnetron
- High-voltage diode or capacitor fault
- HV transformer fault
How we diagnose & fix it
Because a code points to a likely area rather than an exact part, we run a full on-site diagnosis to confirm the real cause — testing the components above and the wiring and controls behind them. You get a clear, flat-rate quote before any work begins, and most MAG faults are resolved on the first visit with quality parts and a parts-and-labor warranty.
