Hayward Super pump question

[Poconos]

Sounds like the centrifugal starter switch is crummy. Check this thread:

The 2x4 method referred to is the trick of whacking the side of the motor with a 2x4 with power on and it doesn't start, not hard enough to dent but the shock will sometimes cause the starter switch contacts to connect. You need to clean the contacts with fine sandpaper or a small flat file. Use something like 400 or 600 grid Wet-or-Dry (auto stores) and lightly dress the contacts. The thermal cutout switch is what is kicking out when it doesn;t start. It's the thing at top-middle of the pic just over the horizontal gray spring.
Hope this helps.

Thanks Al,

I'll take a shot at it in the morning. Great pic by the way! I'll let you know the outcome.

Thanks Al,

That did the trick. It starts right up now.

Glad to hear it worked. Another cheap and happy ending. did you wind up dressing the contacts?

Yes I did, but the pump started doing it again. If you start it up when it's still warm, it starts right up. But when it sits for over an hour, then it just humms. I think it's the capacitor, so I'm going to try that next.

Thanks.

Could be the cap and they are cheap and worth a try. If it's a loud hum then the cap is shorted. If a low level hum then it's open. You can wedge a piece of paper between the contacts to see what the low level hum sounds like.

It's a low level hum. I put a piece of paper in there, and it still made the same noise. The strange thing is that if I let the pump cycle through 1 or 2 times of not starting, the pump gets warm, and will eventually start. Also, if the pump is warm from being used and you shut it off, as long as it's started before it cools off, it starts up just fine.
