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!
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!
Exactly.
There are several varieties. If you run into trouble, post a pic of the back of your motor and we can help you out.
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!
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.
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?
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?
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.
