I got a hot tub motor that continues to shut down on on therma overload. The motor shaft turns freely and when I turn it , it will restart. I am guessing it could be the start capacitor and plan on replacing once I find one. Need to obtain the manual due to specs on capacitor are unreadable.
Question 1 does anyone agree with my diagnosis and question 2, could I use an AC hard start temporarily to keep the motor running. Its below freezing where I live

 

as much info from motor tag as possible.
voltage, amps and hertz it is installed for.
horsepower or watt rating.
