When a capacitor short-circuits, the winding in the motor may burn out. You will likely hear a humming sound if the AC capacitor is bad and your AC will not run. When a run capacitor goes bad, this phase shift does not occur and causes the motor to work harder, and in turn, overheat and destroy the bearings. The most obvious sign of a bad capacitor deals with a bad test from a multimeter. How do you test a capacitor with a cheap multimeter? It is the run capacitor, which supplies the power to the compressor when the Post Temperature Coefficient (PTC) gets hot. eiusmod tempor incididunt ut labore et dolore magna aliqua.

A bad capacitor prevents your AC's fan from turning on, which means your air conditioning system can't move the heat from inside your home to the outdoors. Along with batteries, capacitors are the UPS components most prone to failure. If your AC shuts off without warning, your capacitor is bad. In fact, most natural odors are just VOCs. For a correct measurement, the capacitor will need to be removed from the circuit. An OL or overload reading means the capacitance is too high for the multimeter to measure. A bad capacitor prevents the exterior unit from properly functioning, which hinders the cooling process as a whole. If you think about a capacitor as a large store for energy, you're on the right track. Extended use can cause further damage internally. If a run capacitor fails, the motor can display a variety of problems including not starting, overheating, and vibrating.
