    Not sure of your layout or where your furnace is located. What's on the outside of the RV.

    If you have the large metal plate with the intake and exhaust ports on the side that is where you would start to look by removing that cover. If you only have the intake and exhaust ports then you must access the furnace from inside, under a cabinet or through the storage bay.

    With the exception of heat pump units there usually isn't any 120V power required for the furnace.... the fans, controls, and ignition system are all 12V. Check out all of your 12 volt fuses with a meter and make sure every one is good... you need 12V to operate the furnace. Check your T-stat, does it still work to operate the ac unit? If no then your T-stat could have failed.
