Collection: Motor Capacitors

A start capacitor gives a brief high-capacitance kick at start-up and then drops out, while a run capacitor stays connected to improve running efficiency and torque. Some motors use both, so replace whichever your motor specifies.

The microfarad (µF) value is usually printed on the old capacitor or the motor label. Match it exactly; a wrong µF affects starting torque and can overheat the motor. If unsure, check the motor's rating plate.

Yes, a higher voltage rating is safe, for example fitting a 450V where a 400V was used. Never go lower than the original rating, as the capacitor could fail. Keep the µF the same.

Common signs are a motor that hums but will not start, slow start-up, overheating, tripping protection, or a swollen or leaking capacitor body. These often point to replacing the capacitor before the motor itself.

Yes, single-phase fans, pumps, compressors and gate motors typically rely on a run or start capacitor. See related fans and ventilation and switching gear in contactors and relays.

Isolate the power, wait, then discharge the terminals through a suitable resistor before touching them, as capacitors can hold a charge. If you are not confident, have a qualified electrician do the work. Insulated tools help.
