fan runs when in furnace mode

[geekyguru]

Please excuse my technical descriptions! I am running my furnace at a set temp. The heat does indeed kick on and off as it should. The problem is the ducted ac outlets blow when furnace is not heating. This in turn makes the coach colder! I am not sure if the system is working as it should?? Its been cold as hell lately! Space heaters aren't working so well for my water pump, so I'm using a bit of propane nightly.
Its a bullet 281bhs. Standard crappy thermostat.

Not that many trains left once you get in the west. Sure there is a few but, not near most campgrounds.

Both of the previous post's are corrrect. The fan set on low or high will run independent of the heat or ac. Set on auto the fan will run with the ac and shut off when the temperature set on the thermostat is reached, like in your home.

OR your crappy t-stat is bad-shorted

Easily replaced with a $20 digital battery operated Hunter T-stat from Walmart

Yup. It was in Lo on the fan setting. Changed to AU and good to go now ! Woot.
I'm gonna be a vet camper after a couple months of this cold weather. Six more weeks to go... Come on Spring!!

On the thermostat switch the fan speed to auto.
