I measured the voltage on the blower relay then.
with Cool set to On, Fan set to On, and t-stat at 65, I still have no voltage on contact 1 & 3 which are the wires running to the blower motor.
So is the blower relay my problem then, or is something else more likely?

RE: No blower again
Finally got back to fixing this. Problem is that the transformer in the control box has 6 tabs while the one you recommended has 4. I know 2 are line, 2 are load, and I'm assuming that the other 2 are a ?relay? that gets tripped by the t-stat. So what part am I looking for in that case? thanks again...

RE: No blower again
Will give it a try. Thanks for saving me the house call fee from the local HVAC place.

RE: No blower again
Primary side of the transofmer has 120vac
0vac on the secondary side.
Does that mean the transformers gone?

RE: No blower again
Cool-Auto-65 does not start the outside A/C unit.
Not switches on the metal box, just a jumble of wires going in two different holes. Is that the t-stat control unit?

Question about an Intertherm and finding right manual/parts
Trying to find a manual/parts for my A/C unit. Its a split furnace/A/C setup, the furnace is a coleman, and I've found a manual for that. The A/C is Intertherm, and stamped with "cns30bcraa". That number apparently doesn't mean much. Can anyone tell me where I might find the actual model n...
