Start Capacitors

A start capacitor gives an electric motor the extra jolt of torque it needs to get moving at startup. When a single-phase compressor motor hums but will not spin, or trips its overload on start, a failed capacitor is one of the most common culprits. This collection offers replacement start capacitors to get a stalled motor turning again.

Capacitors are a routine wear item, so it helps to keep a spare on hand along with other motor components. Browse our air compressor motors and related compressor parts when you are servicing or upgrading a unit.
