Coleman Mach 1497-6881 RV Air Conditioner Start Capacitor

The main job of capacitors is to store electrons to provide start-up energy for your air conditioner, they build up a charge when electricity runs through them by swapping electrons between the two conductive plates inside. Because of their capacitors, air conditioners do a little magic trick every time they start up. Your A/C unit actually requires a great deal more start-up energy than is available through your home’s wiring, so the capacitor is added to the circuit to give an electrical jumpstart at the same moment that your air conditioner is drawing power from the electrical grid. Together, these two electrical sources provide the right amount of juice to your air conditioner.

One of the primary signs of a faulty capacitor is the air conditioner struggling to start or failing to turn on, indicating that the capacitor is unable to provide the necessary startup energy. Additionally, a humming noise from the air conditioner unit can be a sign of a capacitor struggling to perform its function. Overheating and shut down of the system shortly after starting are also common symptoms of a failing capacitor. In some cases, a visible bulge or leak on the capacitor body itself can be observed, which is a clear indicator of malfunction.
