    Main Pump Problem

    My pump isn't working and tried the capacitor option, no luck.
    Any suggestion on good motor or should I replace the complete set including the housing. Please suggest.
    Also, any recommendation on who do the good job, pool store or electrician?
    I currently have 1hp, pinnacle / centurion pump. 3450rpm, p56y frame, horizontal mount.
    thanks!

    There should be a catalog number on the motor. You can use that to search for a replacement. If you'll post it here we can help you find one.

    Just so that I can say that I have asked this... Have you verified that there is voltage to the motor terminals when it should be running?

    Is there other numbers on the motor? I get a 2 hp motor from those numbers.

    You mentioned the capacitor, be sure to check the centrifugal switch, too before you spend the money on a new motor.

    Re: Main Pump Problem

    My mental math gets about 2hp, too, from the nameplate 7.1 amps @ 220v, assuming ~746w/hp

    Re: Main Pump Problem

    Volts mentioned is 230/115
    RPM 3450, 60hz
    few numbers I notice:
    174050-01
    175367-15
    part no: 35-5839
    It says 1HP , 1.25 SF

    I had hard time removing the electrical connection since it was locked with pressed plug on the motor and grounding wire had completely rusted. I had to cut it. I took it too local pool store (national spa and pool) to see if it can be repaired. I am waiting for response. I aslo checked few other stores on the motor, I was told motor can be replace for around $275-$300. Anything particular I need to watch for or ask to avoid common pitfall? Please let me know.

    Re: Main Pump Problem

    Hello,
    I ended by a new one A.O. Smith USQ1102 and paid $279 for it. The old motor had rusted was not repairable. Is this a good motor and right price for it?

    That is a good motor and the price doesn't look bad at all.
