If your air conditioner makes a clicking noise when turning on, the AC capacitor is beginning to fail and should immediately be replaced. The same is also true if your AC compressor won’t turn on and makes a loud humming noise whenever it tries to start or if the compressor turns on and then immediately shuts off again. Most air conditioner repairs are not something you can do on your own. For a professional, replacing the AC capacitor is a fairly straightforward task that should only take us a few minutes. Here is everything you need to know about the capacitor and how we replace it.
What Does an AC Capacitor Do?
The AC capacitor stores a strong electrical charge that it releases to help the motor start. Depending on your system, there may be a single capacitor that works for the indoor blower motor, compressor motor, and compressor fan motor. Some systems have a capacitor for the blower motor and a separate capacitor for the compressor and compressor fan motor.
All of these motors draw a huge amount of electricity for a few seconds as they start up. This is typically more electricity than the circuit could provide, which is why the capacitor is necessary.
