Motor Capacitor FAQ
How do I know if my start capacitor is bad? Most start capacitor failures are one of two types. Catastrophic failure is usually caused by an electric motor''s starting circuit being engaged too long for the intermittent duty rating of a start cap. The top of the start cap has literally been blown off, and the insides have been partially or fully ejected.

Capacitors Explained
In electrical circuits, the capacitor acts as the water tank and stores energy. It can release this to smooth out interruptions to the supply. If we turned a simple circuit on an off very fast without a capacitor, then the light will flash. But if we connect a capacitor into the circuit, then the light will remain on during the interruptions ...
