The magnetron and diode can be tested with a multimeter to determine if the components have continuity – a continuous electric path present in the parts. Before you attempt to disassemble the microwave to reach the magnetron, diode, or any other component for testing or replacement, unplug the power cord. Since high voltage capacitors used in microwaves may retain a charge even after the power cord has been unplugged, it is recommended to discharge the capacitor immediately after removing the cover. You can do this by placing a screwdriver blade across each set of capacitor terminals (avoid touching the blade when doing this).
