    2HP AC Single Phase Motor very weak at start or hums

    Well, it wasn't the CAP. I put a brand new one in and it gave the same results. I've been running the pump all day after starting it by hand because my pool started turning very green. I hope running it won't make the problem worse, but at this point I think I'm going to have to buy a whole new...

    2HP AC Single Phase Motor very weak at start or hums

    One more question. I see on Digikey a cap that has the same rating, but it's marked as a Motor Run, not a Motor Start. I don't suppose there's any difference, but since I know more about computers than motors, I figured I'd ask just in case I can't find one tomorrow...

    2HP AC Single Phase Motor very weak at start or hums

    I wish I could, but a year or so ago, I had a pool guy work on it and he either rebuit the motor or put in a rebuilt one. Either way, it was re-painted all black and the only thing I can see a a message saying A.O. Smith Centurian Switchless - No Switch / No Governor - Total HP=2.00 It has...

    2HP AC Single Phase Motor very weak at start or hums

    I have an A.O. Smith 2HP, 220Single-Phase pool pump motor that started giving me trouble. It has been working for the past year or so, but just started having starting problems. When I turn it on sometimes it starts, most of the time it just hums. If I give the shaft end a spin, it will...
