I was able to dig into this on the weekend. The controller is providing 110V to the pump even after the pump shuts off so it would seem the controller is ok. I pulled the back cover off the pump and read the voltage between the 2 leads coming off the capacitor. When the pump is running it reads 79V, when the pump shuts off on its own I have 0V.
Should I replace the capacitor or is them some thermal switch I should be looking at?
If it is the cap, any suggestions on where to buy one online?
