Pump trips when starting on low. Hard to rebuild?

[kne]

I have a 1 hp - 2 speed pump. It runs & will start up on high, but if I try to start it on low, it will try, then trip the plug. If I start it on high, I can switch it to low & it will run.

Right now I am running on high all the time, but would like to fix it. (I'm in California so a new pump is not cheap.) Is this something I should watch youtube videos on and try to fix myself? Ok, really I mean direct my husband on what needs to be done. Anyone have this problem before?

Can you post a picture of the pump and motor, including any labels? You do not show what you have in your signature. Details can help our members provide accurate guidance.

Unfortunately the label has faded. But this is the pump - Amazon.com. I will update my signature.

Likely something to do with the centrifugal switch. Let's see if @JamesW can provide some guidance.

Pictures of the wiring compartment?
