Looking for a reliable replacement capacitor on pool motor

capacitorelectric motorpool

I'm looking to replace the capacitor on the motor that drives my pool pump. The motor just "hums" when I try and start it and nothing is caught in the impeller or binding it.

This capacitor sits on top of a Century B2854 0-F56AA40A01-24 (1.5 HP motor) Picture of this below capacitor picture.

I've attached a picture of the capacitor. I've seen plenty of similar capacitors on amazon, but I wanted to consult some experts to make sure I am getting the same ratings of my current capacitor, and getting a reliable one.

I don't know my brands or companies of electronics and I don't want to buy something that can harm the motor or will fail.

this is not a shopping question but more of an identification question. To answer your question the brand is irrelevant. The cap is 30 micro farad expresses as 30uF the voltage is 370v. Any value 370 or higher will work fine. To get the correct style search for “C65R” then match one that lists 30uF. Most of the time when a cap fails case bulging is visible at the top and bottom. An ohm meter can be used to see if the cap charges and discharged if your meter doesn’t have a capacitance test function.

With the power turned off short the terminals together then pull 1 of the connectors off. Now using the ohms function on your meter put the leads on the 2 terminals you are looking for the value on the meter to start climbing if the value is increasing swap the leads and now the value should be dropping if this can be observed and the case is not bulging it is probably fine. If there is no change in the value the cap is probably bad and it is time to replace it.
