1/2 hp Capacitor-start induction motor, reversible by manual switch, cap is good, centrifigul throw out is good. I believe the thermal overload may be bad.
Motor will hum but not start. If I start it by hand (in either direction) it will run till the centrifigul throw out kicks in then shuts down power. When the motor slows to about stop and the cetrifigul switches the other way the motor runs again. On, off, on, off.
The overlaod is a Klixon thermal with a manual reset. Connectors are P1, P2 and T1. P1 and P2 are the "contacts" while T1 is the thermal.
I have continuity on P2 and T1 but nothing on P1.
I am pretty sure the problem is in the overlaod switch but do not know how to test it for sure.
