How to Replace a Washing Machine Motor Capacitor?

A washing machine motor capacitor is an electrical component that helps start a washer's main motor. A capacitor is like a battery that stores energy and releases it when the motor needs an extra boost of power.

There are two capacitors in the dynamo motor of a washing machine: a starter capacitor that starts the dynamo when the washing or drying cycle begins, and a running capacitor that continues to operate as long as the dynamo is working. The number, size, and magnitude of these capacitors vary according to the type of washing machine.

Some washing machines use electrolytic capacitors, while others use non-electrolytic capacitors. Generally, electrolytic capacitors have greater energy storage capacity than non-electrolytic capacitors.

If the washing machine is not spinning or making a buzzing sound when you set the timer, then the washing machine motor capacitor is likely damaged/broken. It will be able to rotate only weakly and generate a buzzing sound when the dynamo is operating, or it may not even produce a buzzing sound at all.

The first step to replace a washing machine motor capacitor is to unplug the unit. It is also a good idea to make sure the washer's insulated handles are securely in place before beginning any work on it.

Once you've unplugged the unit, locate the washer motor's start capacitor (usually located in the rear panel) and remove the metal cover. The capacitor is cylindrical with two terminals that connect to the motor wires.
