Maybe someone more familiar with furnace electronics can shed some light on this situation. My old expensive (by expensive, I mean I’ve replaced almost every part, arrgg) Coleman T.H.E 90 (late 80’s, early 90’s) furnace stopped working today. I checked everything out and the only problem I could find was a very warm transformer and a burned electical smell, which was coming from the transformer.
My question is this: are parts for this old furnace still availible? Or can I just match up voltage and connections and get a generic transformer? Second, where would I find such parts in a hurry? Does Ferguson or other heating supplier stock something like this?
Wouldn’t know this would happen at the start of heating season! At least it’s not too cold yet….
Thanks for any advice, I need it.

I used to own a house with a Coleman furnace, installed in 1985. They were made for Coleman by someone else, but I can't remember who. A dealer should know. Then contact the manufacturer.
If it is just a transformer, you can replace it with any transformer with the same electrical specs. Match the primary and secondary voltages, as well as the capacity of the transformer, usually stated in VA (volt-amps). The connections don't matter so long as you hook it up right.
It is possible that some other component is shorted and drew too much current through the transformer, then you have another problem.
