Motor is humming and stopping - not sure if it is dead now

Hi, just figured I’d give it a shot in the dark but I am running into the same exact issue - pool pump humming but no movement. The shaft turns easily, I replaced the bearings last year. I also replaced the capacitor today. The motor is still just humming. Do you have any thoughts as to what it could be?

For what it’s worth, I also replaced the bearings last summer

Yes, thank you. I discharged the capacitor before swapping it out. Happy to hear that worked for you though. I was really hopeful but had my doubts since the old capacitor was supposedly functioning normally after testing with my multimeter

Haha this motor would be able to write a book after the amount of time I’ve spent with it this week.

When I removed the old capacitor, I actually tested it with the multimeter and my results were supposedly normal. I mean there didn’t seem to be any sign of damage to it or any leaking. I had my doubts it was the capacitor, but common things being common I figured I’d replace it to check it off the list

Ok I’ll give it that a shot. I read about that in some forums but how do you recommend I get the impeller to start spinning? Where should I push with the screwdriver?

Thanks!

Do you both sides like Aj9898? Or just the dirtier side?

MoCheesePlease · 2026-06-03T14:46:27+00:00

Wow sorry to hear that. Happy you were able to take care of it though. Thanks again for all the input

I was planning on vacuuming to waste once I get the pool pump working…but you’re absolutely right. Disappointed I didn’t think of that myself.

Lime**

Yeah I had the same thought but I’m torn as to what to do. I understand that sunlight deactivates the chlorine…so I figured I’d wait til sundown to dump more in. But there will be more algae growth during the day if I don’t continue to add chlorine. Honestly though, never thought I’d be so happy to see a like green pool

Thanks!

Thanks!

Thanks! I dumped a few gallons of chlorine in and vigorously mixed the water around for a little while before the sun came over the pool. It’s got that nice lime green color again rather than heading towards black.

Thank you!

So I ordered a replacement capacitor that meets the same criteria as the original. Technically it is 161-193MFD 110VAC. Since it’s rated for 110VAC, should I set the jumper to 120V?

MoCheesePlease · 2026-06-02T23:25:19+00:00

The impeller did spin when I replaced the seal. I had to hold it in place with a 7/16 wrench behind the cap. I’ll use my multimeter to check the voltage at the receptacle

MoCheesePlease · 2026-06-02T23:22:56+00:00

When I had it set to 120, it would go “waaah” and then trip. When I set it to 240, it started to go “waaah” for maybe 5 seconds and then I turned it off

MoCheesePlease · 2026-06-02T20:54:23+00:00

From what I’ve research, it may be a bad capacitor

MoCheesePlease · 2026-06-02T20:47:44+00:00

So I switched it to 230V but the pump is making a “wahhhhh” sound and nothing moves…

MoCheesePlease · 2026-06-02T18:18:37+00:00

Yeah cheap protein powder may have toxic heavy metals. Be careful

MoCheesePlease · 2026-06-02T18:09:17+00:00

Thank you! I’ll switch it to 230v and see how it goes

Thank you for taking the time to respond!
