Description

This high-voltage diode rectifies AC to DC in the microwave's high-voltage circuit so the magnetron can generate heat. When it fails, the oven may run normally but won't heat or may blow fuses.

• Converts high-voltage AC to DC for magnetron operation
• Maintains correct polarity and protects the HV circuit
• Common failure symptoms: runs but no heat, loud hum then shutdown, blown internal fuse, or tripping breaker
• Visible burn or damage on the diode or leads may be present

What's included: 1 high-voltage diode

• Disconnect power before servicing; high voltage is present even when unplugged
• Safely discharge the high-voltage capacitor before touching HV components
• Match orientation to the original—polarity matters; ensure tight, insulated connections
