Use this guide to discharge a capacitor in your large device. If you''re discharging a capacitor for a small device, follow this guide instead.
A capacitor stores large amounts of electricity even when your microwave is unplugged, and it must be discharged before beginning any repair. A capacitor is discharged by creating a short circuit between each of the two capacitor terminals, and between each terminal and the chassis. The chassis is the metal mounting (bare metal surface) of the ...
Microwaves are among the most hazardous appliances to repair. They contain large, high-voltage capacitors capable of delivering a fatal electrical shock, and can also leak harmful levels of radiation if damaged or reassembled improperly. ... Nevertheless, assume all large capacitors are charged unless you have confirmed otherwise. Safely ground ...
The two most common types are electrolytic capacitors and ceramic capacitors. Electrolytic capacitors have an anode and cathode, while ceramic capacitors typically only have two leads that connect to the circuit board. Tools Required To Test A Capacitor. Testing a capacitor on a circuit board requires the use of specialized tools.
