    Motor not working?

    [attachment=0:3cezaf2s]photo 2.JPG[/attachment:3cezaf2s]I just noticed my there is not water running in the pump,
    The Jandy Aquapure shows no service/error code.
    when I turn the pump on, it makes the running noise for 3-4 seconds and then goes silent. No noise of the working pump. The pump motor was very hot on touching, so I am assuming I had lost the pump motor and it needs to be replaced.
    i would appreciate if you could tell me what motor it is, I am attaching the pictures of the motor.
    its about 18, 000 gallon salt water pool. I was wondering whats the advantage of having a 2 speed motor.
    the pump is Jandy Stealth SHPM2.0
    Another thing I wanted to know is, if the motor can be repaired at all, or it has to be replaced?
    Appreciate all the help.
    Thank You

    Re: Motor not working?

    What you have is a B2842 Centurion motor.

    First a couple of questions.
    Does the pump actually run during those 3 to 4 seconds or does it just make a humming noise?
    Have you tried manually turning the shaft with the power off?

    It could be just a bad capacitor (the bump on top) and if so, they're easy to replace.

    If it's a bad motor then you can change just the motor out with a 2-speed. You could use a B2983 or a B983. The 2983 has a low speed sfhp of .28 and the B983 has a low speed sfhp of .37.

    Re: Motor not working?

    It just makes the humming noise for 3-4 seconds, the pump doesn't run.
    How do I turn the shaft with power off? i will try to find the shaft.
    and how do I diagnose that its a bad capacitor and not a bad motor? What kind of capacitor should I buy if I just want to check if its bad capacitor?

    Thank You.

    Re: Motor not working?

    The one part of the motor you didn't take a picture of was the back cover. However, If you remove that you should be able to see the end of the shaft. There'll either be a screwdriver slot or flats for a wrench on it. Just try and turn it and if it turns fairly smoothly I'd suspect the capacitor.

    To replace the capacitor just remove the screw(s) in the bump and take it off. The capacitor is under that. It just unplugs. replace it with the same (or very close) mfd rating and a equal or higher voltage rating. If you have a local electric motor shop they'll have them in stock most likely.

    could be the capacitor, try changing that out first

    The Shaft spins freely with hands,
    Will try changing the capacitor and hope it works.

    Thanks a lot

    Re: Motor not working?

    The Capacitor doesnt mention the MFD value. How to find the MFD. Is it the UF value mentioned there?
    Thanks

    Edited, I guess I figured it out. its 50 micro farad, not 50 UF

    Re: Motor not working?

    You got it right it's 50 microfarad 370 volt. That's a pretty common value. Is/Are the end(s) bulged?

    Re: Motor not working?

    The Greek letter 'mu' (lowercase), 'µ' is used to represent micro, so you'll often see the symbol µF used to represent microfarad.
    Caps are cheap, so it's pretty common to just replace one as a test.

    Re: Motor not working?

    Changed the capacitor today, and the pump is working.
    The capacitor was a little too big to fit in the "hump", so just need to find the right size, or order it online.
    Thanks a lot everyone.

    Glad it waws simple. Ordering it online may be your best bet. Make sure you get the size needed to fit in the cover.
