Stumped by this Hayward Pump

[JamesW]

The only way to properly test a capacitor is to use a meter that can test for capacitance.

When you have a three terminal capacitor, you use the "C" and "Herm" terminals and you do not use the "Fan" terminal.

It looks like the meter can do capacitance.

Check the silver run capacitor for capacitance between the "C" and "Herm" terminals.

Which terminals are you using?

I just confirmed that I had the top capacitor on the C and HERM lead. Same operation as before.

I don’t think my multimeter measures capacitance - I have a new meter coming Tuesday so I can check them out.

Thanks again for your help!

OK, I don't know what is going on with the pump.

I would contact Hayward (Pump manufacturer) and Regal Beloit (Motor manufacturer) to see if they can identify the problem or offer any warranty assistance.

Thanks for your help. With the cost of just the diagnostics for the motor I’m beginning to think I should just order a new motor and be done with it. I am still going to wait for my multimeter to arrive and test the capacitors just to see if somehow the new ones I got were bad.

I never really used the 2 speed operation so I’m wondering if I can just replace it with a single speed motor. Would this one work as a direct replacement (I would leave the A wire capped off)

Thanks so much.

You can use a single speed.

I would recommend a two-speed or variable speed.

A VSP is much quieter and it uses much less energy.
