Bosch HMC80152UC 800 Series 30 in Convection Speed Microwave E1 Error Fix: Magnetron Failure — Not Heating

The magnetron (the component that generates microwave energy) is not producing output. Food placed in the microwave is not heating. Check high-voltage components: the magnetron, high-voltage capacitor, high-voltage diode, and high-voltage transformer. **CAUTION: The high-voltage capacitor can hold a lethal charge (up to 4,000 volts) even when unplugged — it must be properly discharged before testing any high-voltage components.** Check the magnetron thermal cutout (TCO) for continuity. Professional service is strongly recommended for magnetron and high-voltage component replacement.
