A capacitor is responsible for starting the compressor, and if the compressor has trouble starting, it could pull too many amps and trip the breaker. Over time, contactors experience wear and tear. The capacitor can drift significantly in capacitance. When you turn off your AC, the contactor goes up, blocking power. Imagine a very large battery that can give up all its stored energy in a single pulse. Problem Indicators/What You Can Do. When the thermostat calls for heating or cooling, a magnetic action occurs. Finally, AC capacitors simply fail because of age. Improper voltage or current traveling … Like any piece of machinery, they degrade over time, although they are designed to last for a long time—up to 20 years. Eventually, the dielectric material inside the capacitor dries up or creates a bridge that prevents the capacitor from storing energy up. Many people have asked me “Why do Air Conditioner Capacitors Go Bad?” Capacitors typically have a life as measured in cycles. The type of compressor also makes a big difference - the normal (probably vast majority of household units these days) scroll type compressor has a lot less starting resistance than a sliding vane or piston type compressor so the capacitor does not work as hard. A bad motor capacitor may cause starting problems or could shut off the motor while running. AC Not Blowing Cold Air.
