Your A/C sometimes does not turn on right away, or does not turn on at all.Your A/C creates a low humming sound that wasn’t there before.How Do You Know if Your Run Capacitor is Failing? One thing that could shorten its lifespan is letting the fins of your outdoor coil get so dirty and clogged, air cannot circulate properly, making the compressor work harder. That said, failed capacitors are probably the most common cause of A/C repair. Most run capacitors are designed to last about ten years. ![]() These problems can be detected and eliminated during regular AC preventative maintenance. A dual capacitor powers both the fan and the compressor, which is the big pump housed in your outdoor cabinet that circulates refrigerant between the indoor evaporator and outdoor condensing unit. The good news is, as much as 80 percent of the causes of AC compressor failure are preventable if the problems leading to the failure are corrected in a timely manner. A lot of torque is necessary to start up an AC system, so a start capacitor will have greater capacitance than a run capacitor. The start capacitor provides the initial energy needed for start-up. Without the run capacitor, the fan cannot turn. The run capacitor, also sometimes called an “A/C capacitor,” uses its stored energy to turn or run the fan motor. Depending on your air conditioning unit, it may have multiple capacitors. Each time your air conditioner turns on, the capacitor provides a new blast of energy. As your air conditioner is running, the capacitor collects and stores energy, similar to a rechargeable battery. When your thermostat tells your air conditioner to cool the house, the capacitor’s job is to provide two hundred forty volts to start up the compressor, fan motor, and blower motor.Īfter the capacitor jumpstarts those parts, your A/C can begin cooling outside air and blowing it throughout your home. It has the ability or ‘capacity’ to save energy in the form of an electrical charge. A capacitor is a small cylindrical device inside your A/C unit that supplies and stores energy.
