I have a Montana 3781RL and sometimes after changing propane bottles, I have some issues with the furnace. If you try to ignite the furnace a few times, there is a safety so you don't blow the camper up. Before replacing components, try pulling the Furnace panel and look for the Rocker Switch on the blower motor. For me, I can switch this off for about a minute, turn it back on and this resets things. Try the furnace again, if that didn't fix it, could be the air flow switch.
