I have a Jandy Stealth Series Pump SHPF 3HP which just quit working a few days ago, basically it would trip the breaker for some reasons, if I reset the breakers and try it again, it would try a few seconds (I can hear some noises) then trip the breaker again. First thing I tried was to check the run/starting capacitor with a multimeter, the capacitor value looks to be alright, ~50 uF. Then I removed the motor from the pump body, and found that I can turn the impeller by hand, so it's not stuck or anything. What should I check next? Try a new capacitor anyway? Or just replace the entire motor? Any suggestions?
Thank you for any advice!
