Replacing pool pump motor capacitor.

We get a lot of questions concerning capacitors on pool pump motors. There are basically two types of capacitors used on small pool pump.

Replace your capacitor when the shaft or impeller spins freely and when powering the motor you hear a buzz or a hum from the motor which may trip the breaker.

If you don t have the exact replacement value can larger or smaller value work ok. The smaller black capacitors located in the rear of a motor are usually labeled with a range of numbers i e 161 193 mfd while the larger silver capacitors typically located on the hump of the motor on top are sized by a uf. For example this one is a start capacitor rated at 124 149 mfd and 125 vac. Look for their mfd or uf and vac specifications.

If you can t find your size capacitor it is acceptable to use the one rated one step higher. Start capacitors have a limited service life of approximately 5000 starts of the pool pump motor. If you pump motor is continually burning up capacitors try using the next one up in size. Try to replace the bad capacitor with an identical capacitor.
