I just went to Grainger and brought my whole assembly there with me.
We took the motor off the wheel (took a little convincing, but came
off) and the guy looked up the replacement.  My original is a 1/2 hp GE
unit, the replacement he found was a Dayton 1/2 hp same rpm (can't
remember now), same shaft, the only difference is the replacement is 3
speed, the original is 4 speed.  I had the high and low connected to
what probably is cooling and heating.  I noted down all the connections
when I removed the original and will hook up the new one the same way.
Total cost with the new capacitor: $69.20.  If this works when I
install after work tonight, I will have saved a lot of money. Thanks to
all for encouraging me to replace.  My hesitation was due to lack of
knoweledge of where to get the replacement.  Grainger seems pretty good
for that.

Thanks!

great!!!!

if you feel like buying yourself a present with all that money you
saved.......

go to Radio Shack and buy a clamp on current meter and you can easily
check the current draw of your new motor and make sure it is hooked up
correctly...

Better still, you can get a serviceable one at Harbor Freight for
probably under 20 bucks (they were on sale for $12 a few weeks ago).
I checked the one I bought against an RMS in-circuit ammeter, and
it seems fine.


Actually they are %9.95 on sale here at Harbor Freight, digital read out. A clamp meter has two jaws that go together forming a hole. What you do ,Vladimir, is open the jaws so you can move one of the hot wire into the hole and then release the jaw. The meter will show the amps in that wire when the motor is running.
