bouncybounder Posted September 9, 2019 Report Share Posted September 9, 2019 (edited) Hello, my Rv has two furnaces. One in the front under the refrigerator and the second one is around where the shower is located. The fan works on both the front and the back furnaces. The front furnace puts out heat but not the rear one. I don't think it is a problem with the thermostat or the control module for it....It could be an issue with the propane not getting to the furnace or maybe the furnace needs to be repaired? Both run on propane which I know works. Any tips or ideas you guys have might be helpful. Does anyone know of valves/switches that need to be checked? Or the best way to access the furnace? Edit: The fan makes a loud screeching sound when it fist starts and then after a minute or so goes quite and the vent continues to blow cold air.
