What is a high voltage capacitor?
Stores a charge that can kill you, and holds it after the microwave is unplugged. This is why microwave repair is professional work.
The high voltage capacitor works with the transformer and diode to supply the magnetron. It stores a lethal charge and retains it after the appliance is disconnected from the wall, sometimes for a long time. It must be safely discharged through a suitable resistor before anything inside the cabinet is touched. This single component is the reason every guide on this site draws a hard line at the microwave cabinet. Filters, bulbs, the waveguide cover and turntable parts are fine for owners, and anything behind the case is not.
