No Furnace

[Travelling Three]

We have a 2017 Montana 3661RL. When turning on the furnace nothing happens, no fan, lots of nothing. On the ignitor board the red LED blinks once every three seconds indicating a bad air vane switch. I took the air vane switch out, measured continuity and the switch is operating properly. Before I go any further I would like some possible suggestions as to the problem. I have propane in the bottle. Were camping at 10,000 feet but the furnace has been working fine. That's for any suggestions.
