I bought a programmable thermostat to replace my old one. It comes with instructions for hooking it up to a furnace with one or two transformers. The instructions are different depending on the number of transformers.
My furnace is a GE model BWV936G110D0. I don't have the manual to find out if it has one or two transformers.
Does anyone know where I can find out if it has one or two transformers?
