Dingfeng Capacitor -- How do you know if start capacitor is bad?

Issue Time:2019-07-04

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. Similarly, a start cap may just exhibit a ruptured pressure relief blister. In either case, it's easy to tell that the start cap is in need of replacement.
