Thanks for some input. I had thought of seizing also. but, i have my doubts. the spa has little time on it for it's age. I took the pump out of the tub when replacing the start&run capacitor, and pulled the front housing and cleaned and inspected it, looked great, smooth rotation. So i'm bringing home the temperature gun and a switch. Going to pull the pump off and open it re-inspection. pull wires off the circuit board and run the pump and observe for noise,heat & smoke. The 3-4 years it has been sitting this time, i keep thinking maybe? something has built a nest on the back side of the circuit board? wasp,spider, ect. Maybe to short circuit the board out?
Thanks again
