Using this motor start capacitor is quite simple. First, make sure your washing machine is turned off and unplugged from the power source. Then, locate the old capacitor in your Whirlpool washing machine and carefully remove it. Connect the new capacitor using the 6.3mm spade terminals as per the wiring diagram of your machine. Once it's connected properly, plug the machine back in and turn it on. As for maintenance, keep the capacitor clean and dry. Avoid exposing it to excessive heat or moisture. If you notice any signs of damage, such as a swollen body or burnt terminals, replace the capacitor immediately. Always follow safety procedures when working with electrical components.
