Hi Grant,

It's probably still the start cap. Given the relatively low expense of
electrolytic capacitors, I'd just replace the start cap and see if that
fixes
it. My guess is it will.

Take off the "bubble" on the side of the motor and look at the start cap.
It may
obviously be defective, or maybe you can just get the numbers off it and
take
them to Grainger or wherever you go to buy a new one. Easy to splice it
back in,
simple fix. Even if that isn't the problem it won't hurt and it will
probably
only cost you like $7.

Well, not quite. I've been told by two repair houses that this cap costs
$50. I want to make sure it's dead before I replace it.

Thanks,
Mike
