AC fan on?
Is it OK to leave the AC fan on continuously? Or, overnight...for white noise? We used to do this with our pop up, but the thermostat and AC unit were a different kind.

We run our fan most of the time for air flow and to keep the trailer cool if we do not need the AC. If the heat is on we do not run the fan as it would bring in cold air from the outside. We sleep with the tv on so we are not running the fan for white noise. Generally don't open the windows either.
How would it bring cold air in from outside?
RV A/C Units do not pull ANY outside air in............outside air only cools condenser (coil under slotted rear area of roof shroud)
The trailer air is pulled up thru ceiling return vent/filter across evap coil (where the air gets cold) and then out thru ducts/ceiling grill by the room fan.
Fan recirculates inside air only.....be it cool spring air/cold summer a/c air or warm winter furnace air.
Yes, the unit is only recirculating air, not pulling it in. However, the fan blows the air over the heat exchanger, which is exposed to the outside. By definition, a heat exchanger streamlines the exchange of heat energy. When you're running the A/C, the evaporator coils are cold and cool the air blowing through them. In the winter, the coils are cold because they're exposed to the outside air, and will cool the air as it's blown through them.
Evap coil is enclosed/sealed/insulated from outside air (otherwise the hot outside air would suck up all the cold air).
Remove return air filter.look inside and you will see evap coil.
