Hello all. Need some help fixing a motor. I have a Hayward power flo lx sp1580z2 1.5hp pool filter motor. Breaker popped and the motor now only hums when turned on. Did a few searches to see if I could fix it. The shaft spins freely so I thought it was the capacitor. After taking it apart I see no capacitor. The ones I saw online were silver cans. There is a small connection board with contacts that looks fine. The only other thing in there is a Klixon CGJ133 small round plastic case with 3 wire connects and 2 wires going to it. From searching online I’m guessing it’s a thermostat that is not available anymore. Replaced with a M2 series. Again that’s from a little googling.
Is there a capacitor or anything else in that motor that could be bad or do you think it's the Klixon thermostat I should try changing?
