Unfortunately I couldn't find a replacement switch. I did a lot of searching and one spa guy even said that these cheap XL type pumps don't have replacement parts. I finally gave up and ordered a new pump/wet-end for $200 and it works great. LOL Thanks again for all the help.

I cleaned the contact with the emery cloth and then reassembled the motor. Unfortunately the problem didn't go away. I'll start looking for a replacement switch. Thanks to everyone that helped me work through this problem. I've learned a lot!

The motor is about 2 years old.

Ok, I'll try that. Do you think something needs to be adjusted so it doesn't happen again? Or is there a lot of leeway in the switch/governor and this was just a fluke?

Looks like the high speed contact is burned. It is definitely different from the other contacts. Is there some way to clean the contact or do I need to buy a new switch?

Yes, both springs are on the governor. Yes, the large washer moves along the shaft. You can see in the picture with my thumb that the washer is being pushed and the governor(?) opened.

My easy fix of replacing the capacitors didn't work for long. I've opened up the motor to get a look at the centrifuge switch and it's unclear what to do next. Are there any tests I can do? Maybe just lubricate the switch?

It turned out to be an easy fix. I replaced both the run (25uf) and the start (50uf) capacitors and the problem went away. If the issue happens again I'll take a look at the centrifugal switch. Thanks for all the help!

I'd never heard of a centrifugal switch before, but I watched a youtube video on them and think I can find and test it. Thanks!

I'll take out the two capacitors (I assume one is the start and the other is the run capacitor) and test them. I may just replace them as they are not expensive. Taking apart the motor/pump is more complicated but I'll try that next if necessary. Thanks!

When my spa motor tries to go into high-speed, the back end of the motor stutters for awhile and then usually starts. This happened infrequently in the past but now it happens every time. I've attached a video with sound. Any idea which part of the system might be causing the issues? Thanks...
