What thermostat ? Dometic digital? Suburban? Remember you MUST have 120VAC shore power to run the ceiling fan inside the A/C unit. It will NOT run on 12VDC alone. The furnace CAN run on 12VDC alone, but the fan setting MUST BE AUTO. My Dometic had three fan settings : Auto, Lo, Hi In heat mode, the correct setting is AUTO, and must have a 12 volt battery installed (strange but true or the furnace control board gets snippy, it likes a solid 12 vdc and the converter doesn't do smooth DC) In Cool Mode, Lo, Hi, seemed to work, and must be on shore power (120VAC source). No 120VAC, NO A/C fans. In Fan mode, Lo, Hi, and must have shore power (again 120VAC or no fan). ------------- 2017 ATC 7X20 Custom Toy Hauler 2013 R-Pod 177 (SOLD) 2013 VW Touareg TDI |

I just went out and played with mine. My furnace fan will only come on when I'm Heating. And only blows at 1 speed, I could not get the furnace fan to go on by itself. It will not go on at all unless the gas is turned on and the temp is turned up higher than the inside temp. The ceiling Fan will not come on unless I have shore power, with shore power it has high or low and ac Sounds like the pressure sensing switch is acting up if it blows but no heat.
