Replacing an AC capacitor is a relatively simple task that can be completed in a few minutes. However, it is important to note that capacitors can store a charge even after they have been disconnected from a power source, so it is important to take precautions to avoid getting shocked.
The first step is to turn off the power to the AC unit at the breaker panel. Once the power is off, you can remove the access panel to the capacitor. The capacitor is typically located near the compressor and will have two or three wires connected to it. To remove the capacitor, simply disconnect the wires and unscrew the mounting bolts.
