Quick Navigation. ... a day or two of not running will not result in anything bad. There are basically two types of capacitors used on small pool pump motors commonly found on residential in ground pool systems. As you can imagine, a bad capacitor is going to have other measurable characteristics that are suboptimal. So I walked out to my pool today and noticed that there was no water movement and the pump had shut off. This style of motor has a supplemental circuit consisting of a start windings and capacitor to increase the starting torque by 150-175% while decreasing the starting current. Re: Pool Pump Capacitor?
