I have a arwood furnace and a dometic ac and dometic thermostat on the thermostat i set it to ac it comes on right away i switch it to heat and i get nothing no fan no ticks nothing. So i go to my furnace and there is 2 blue wires marked thermostat if i put the together the furnace works perfectly. I have a 2013 layton joey park model 37ft the thermostat is the digital version 3 button style. Anyone know what this could be. I checked all connections at thermostat and furnace and at the control box they all seem fine.
