any make will work, just as the VA, input and output voltage is the same. Sorry but no way to get heat without that low voltage transformer.
Thanks for the reply! So if I bring the old one to a hvac supply house they should be able to get me what I need? Do I need to know if its 120 or 240volts?any make will work, just as the VA, input and output voltage is the same. Sorry but no way to get heat without that low voltage transformer.
Yeah you're probably going to get a multi volt one. It's pretty easy to hook up as the guy above described. And pretty much if you have an electric furnace it's almost always 240v gas or oil furnaces will always use 120vThanks for the reply!

So this morning I picked up a mars 50327 this morning as thats all I could in stock locally. So my old one is ht01aw230 carrier, 60va 24vac and the 230v was used, not the 200v. I hooked up my mars as follows, used the black to black and red to the orange on the mars. Is that right? Cause what happened was it powered up and once I turned on the the blower and heat the transformer started to smoke a bit and now doesnt work, and the reset doesnt do anything, think I blew it. Did I hook it up right? Since I have the old one out and now know the exact part number will order the exact replacement...but could it be that it was hooked up wrong or does it matter that the mars was rated at 50va and the original is 60va? The blue wire wasnt used on the old one. Thoughts...
Just an edit on this, looks like this pic is actually of a different model mars transformer. Post a pic of this sticker on the one you installed & I can double check for you.![]()
Assuming this is what the sticker on your transformer says I think you hooked it up wrong. Sounds like you're saying you used the black & orange wires. The way it should be hooked up is one high voltage wire to common (white) the other to 240 (orange).
From all the picture I found online of the transformer he bought it looks like it has a built in breaker, so if it shorted he should be able to reset it, but it shouldn't have smoked either so I doubt that's it.Sounds like you went too small. The 60VA is the power rating and you went 15% lower or more. I would say you should throw and ohmmeter across the low voltage side and look at the resistance. You should have more than 10 ohms and likely it's barely over. Higher is great, lower is bad!
If its lower, then you probably have a short that took out the first one. If it was a short though, it would've smoked instantly. How long did it run?
Just to clarify, throw the meter across the low voltage side wires with the transformer disconnected, not reading the transformer.Sounds like you went too small.

And while you're at it, take a reading across the two input wires and the two output wires ON the disconnected xfirmer and we can tell you if it's smoked.
Thats cause you wired it wrong the first time.
You should have wired the transformer orange to line black, and the transformer white to line red. You also got a smaller transformer then you should have.
Get an inline fuse also if the new transformer doesn't have its own.
The way you wired it would've put some seriously high voltage on the motherboard but you need to replace the transformer and check the resistance of the low voltage circuit before hitting it up again. Yes, the white and orange are the correct terminals for 230-240 input.So the guy at the store told me wrong....in input into the transformer are 2 hot wires 120v each...he was the one who said to do the orange and black wire....you are saying I shouldlve put the hot to the white/common and other hot to the orange? I want to be sure I know exactly what do tomorrow when I go and get the right part Ht01aw230... I dont have the transformer with me so cant do the ohms test mentioned but will tomorrow because am curious if it still works/whats up with it.
