My husband and I are doing some mods to our 5th wheel, and decided to remove the furnace (Florida folks), and put in a fireplace. My husband tore out the old furnace, and tossed it, but when we tried to turn the AC on, it no longer functions. Neither the fan nor the compressor will come on. We replaced the original thermostat several years back with a Hunter, and it still works, so that isn't the issue. It turns out that there were several wires (matching the colors going into the thermostat) plugged into the furnace that my husband ripped out, and if you jump one of them (blue) to the 7.5 DC wire, the fan will turn on, but no compressor.
I'm guessing that the wires to the furnace also connected to the AC unit, and that is our issue, but I have no idea which ones, and I'm a little hesitant to just start jumping by trial and error, lest I burn out the AC somehow.
Does anyone know how an RV furnace generally wires to the AC, or how to wire the AC directly to the thermostat, bypassing the furnace?
Thanks!
