Using this capacitor is quite simple. First, make sure the power to the appliance is turned off. Then, locate the old capacitor in your appliance and carefully remove it by detaching the wires from the terminals. Next, connect the wires to the 4 x 6.4mm spade terminals of our new capacitor. Once the connections are secure, place the capacitor back in its original position. As for maintenance, there isn't much you need to do. Just keep it clean and check the connections periodically to make sure they're tight. When handling the capacitor, always be careful as it can store electrical charge. If you have any concerns or if the capacitor seems to be malfunctioning, don't hesitate to contact us.
