Hi everyone, We have a central AC unit in the house. The heat is a separate unit which is hot water base board heat (gas). The AC was making a loud noise from the air handler in the attic. I opened it up, pulled the blower motor / blower wheel assembly out and it looks like the set screw that holds the blower wheel onto the motor shaft broke. Part of the set screw is inside the shaft (like the screw snapped off). Before replacing the whole assembly (looks like the motor is $760 and fan is $124 :eek:), do you think I have any options here? Is it possible to get that broken piece out of the shaft? Maybe with one of those "broken screw removal tools"? Or possibly drill through it and use a nut and bolt instead of a set screw? Or perhaps you can't drill through that shaft? Just thinking out loud. Hopefully you can see the picture of what I'm talking about attached. Thanks!

My AC runs normal for about 6 minutes(timed each time) then it cuts off. When it cuts off after i meter the Rh and C wires and get 0v. After probably 10-15 minutes i meter again and it gives 28v and the AC will start up again for another 6 minutes. Would that be the transformer going bad or could it possibly be something else? Thanks!
