Sta-Rite PS18-148 15 MFD Run Capacitor
The Sta-Rite PS18-148 is a 15 MFD, 250V run capacitor, used to keep the pump motor running efficiently once it has started. A weak or failed run capacitor makes the motor draw more current, run hotter, and hum without turning at full strength.
A capacitor that has failed or drifted outside its rated value is a common reason a motor hums but will not start, or starts but trips its breaker under load. Match the microfarad rating and voltage exactly, since a substitute that is close but not exact will shorten motor life rather than fix the problem.

Frequently Asked Questions
Q: How do I know if my capacitor has failed?
A motor that hums without turning, runs weakly, or trips its breaker under load are the usual signs; a bulging or leaking capacitor case is a clear visual sign as well.
Q: Can I use a capacitor with a different MFD rating?
No, match the microfarad rating and voltage exactly. A capacitor that is under or over the correct rating will run the motor hot and shorten its life.
Q: Is it safe to handle a removed capacitor?
Discharge it across its terminals with an insulated tool before handling, since a capacitor can hold a electrical charge after the pump is unplugged.
