    I've got a pool pump that no longer works. When turned on I can here the hum
    of power from the motor but it doesn't do anything else.
    Is that likely to be a motor burnout, bearings, or something else?
  2. If the pump is still connected, I'd guess that something is
    jammed in the rotor - a small piece of stone for example.

    If not, or you remove the rotor and the motor still doesn't
    run, the seal has probably failed and the motor bearing is
    rusted shut. If it's bad enough to stop the motor, it's bad
    enough to need replacing.

    Apart from that, there's a variety of afflictions that are
    general motor failures, nothing to do with pool pumps. But
    my bet is on the two suggestions above.

    jammed rotor or seized bearings. if you can get it to spin freely with
    no power it should run.

    If the pump spins freely, then it is most likely the starting capacitor.
    If you apply power and start to spin it by hand (watch your fingers
    etc), it should keep spinning. If so then replace the starting cap.

    tya. It was a capacitor, cost $90 to repair.
