Guys-
thanks for all the input- found that indeed the centrigugal switch was
sticking, did a little cleaning and lubed it and all seems OK so far.

If you check inside the motor, you will probably find the centrifical
switch
is used up and not making good contact when the motor stops.

I have a 1 HP induction motor with capacitor start and capacitor run. As
I
understand the function, the start capacitor circuit is engaged at start
up
and then dis-engages when the motor reaches full speed. The motor works
fine most of the time, but every so often it will make a terrible sort
of
vibrating racket and blow the breaker. Sometimes if I just wait a
minute
or
so it will start and run fine again. Any ideas on what could cause
this?
