Hello Hello.
Long time listener, first time caller. I have been trolling this website for the past year and literally have found answers to probably over 100 questions in my adventures of a first time pool owner. But, alas I need specific help.
So, I have a pool, spa and jet pump… all different brands and different ages. My issue is the 2 hp spa pump. This originally was a WhisperFlo and I still have a WhisperFlo basket and impeller, but the motor was replaced by a pool guy under my home warranty with a US Motor pump that he “hooked” me up with. So, my spa pump is kind of an overpowered Frankenstein at 2 hp for only about 450gal.
On the evening of the 4th after running for a few hours, I went to turn on the pump to mix some chlorine. It would hum, but not turn on. Now of course I did my due diligence and investigated on TFP.
I understand it is most likely a start capacitor issue. Motor hums but does not start, impeller spins freely, and I took out the capacitor and tested it and it’s bad, and found a similar one on amazon at a great price. It seems like I know what I am doing, but I still have questions.
In doing my research I was under the impression that a run capacitor has a range of 15-50 MFD and 370 VAC while a start capacitor has a range of 50-400 MFD and 125 or 250 VAC.
I removed the rear cover and everything looked pretty normal until the capacitor that I assumed was in the location of a start capacitor has the 370 VAC of a run capacitor.
Is this a run or start capacitor?
Does it matter?
If this one is bad should I replace regardless?
Also, anything I find online that matches the numbers are capacitors for HVAC. Is that normal? What is an AC capacitor doing in a pool pump?
And I know I probably answer my own questions, but I would like to have the knowledge. Thanks for everything.
