The Fan Sail switch is most likely the issue. Set the Thermostat to off. Remove the furnace access panel on exterior of RV. Turn off the service switch. Carefully remove the sail switch and actuate it by hand a few times. Reinstall the Sail switch . Turn the service switch back on . Reinstall the access panel. Turn on interior thermostat and unit will most likely fire up. These newer units have to prove the sail switch is open prior to starting the blower. Sometimes they just simply get stuck from lack of use. I have to do this to mine every heating season.
