Be sure to check it over. About half the time the transformer got taken out because of something else it was feeding shorted to ground

Just don't buy a transformer from home depot they won't have enough VA
He's right about that. I find a lot of bad transformes due to shorted contactors
40VA transformer with 3 amp ATC fuse with spades connectors. Fuses are cheaper than a transformer.
When I first put the new transformer in I always have my amp probe on the secondary wire and hit the door switch to watch the amps.
Shouldn't be more than .75 amps or so. Anything over 1.0 is suspect and anything over 1.6 blows the transformer, not the fuse.
New transformer has me running, thanks for those that responded with info, I will still need to be researching replacing the furnace as it will become necessary sooner than later.
Once again Furnace is functional transformer was bad.
IMO, 20 years it's time when funds allow, to replace.Quote:

But good job on getting it fixed
I know that "Ballpark estimates" are difficult without actually inspecting the installation site but is there a formula for determining the size of furnace required for square footage of home?
My home was built in 1942 (basement + 1st floor) each level is at most 750 square feet. so a total of 1500 square footage to heat. House was originally a coal fired gravity hot air octopus type set up which was then retrofitted with gas.
The "octupus" could be reworked to make the setup more compact and some of the cold air ducting could use a clean up.
I of course do not have a clue as to what the appropriate size of new "standard" furnace will be, what is the price range of the actual furnace for such square footage. (just the physical equipment not the installation). I realize there are all sorts of factors involved in that, efficiency rating, square footage rating, air conditioning and humidifier add on's etc..... But for the basic furnace component is it usually just a couple of grand?
