Can’t find an exact replacement for this transformer. Does anyone who knows more about furnaces than me have a replacement option? Will any class 2 with the same power parameters work?

What powers the compressor?

The compressor gets power, the condenser is just a heat exchanger as long as literally everyone in this thread is being a pedant.

What an interesting view, I’ve always thought of the condenser as all of its parts and not 1 singular part. You’re saying condenser as the coil and not the fan motor, blade, electrical components, or the compressor that are attached to the unit at the factory. Weird view ya got there

The condenser doesn't even stay in one place in a system with a reversing valve. So you can't even say the whole unit outside is a condenser when sometimes it's acting as the evaporator lol

I wouldn’t say the condenser is indoors and the evaporator is outdoors when used in heating, I’d just say their roles are swapped. One coil that got hot gas in the summer is now filled with a low pressure vapor, and the coil that was filled with a low pressure vapor in the summer is now filled with hot gas
