Connecting Two Blue Wires on Atwood Air Command Rooftop RV Air Conditioner # AT15028-22

Updated 09/05/2019 | Published 09/04/2019

Question:

Can you please tell me where the Blue wires connect on this unit. We have it installed with all the other wires connected and the cool air works fine but we cannot figure out what the blue wires connect to and not sure that the heat pump is connected. We see the diagram that shows they hook to the furnace but do they just tie into the 12v supply? There were no existing wires run to the top that ran from the gas furnace. I have read other QandAs but I need it broken down in an elementary version.

Coming from your furnace there should be 2 wires, an input and an output, to which the two blue wires from the Atwood Air Command Rooftop AC # AT15028-22 will connect. I recommend starting at the furnace to try and locate these two wires.

It doesn't matter which blue wire you use for which circuit/function, as they are interchangeable. I hope this helps but if you still need some assistance please let me know and I will be happy to try and look into this further.
