Is this an AC capacitor start motor on this?
If so it sounds like the centrifugal switch is not operating properly, if it stays open permanently, it usually will not go into run, if it shorts together, then the start windings are in all the time and causes high current, if this is the problem, and you haven't already burnt the start windings, the switch can be replace by taking the end bell off of the motor.
