Circulating warm air in underbelly

I read on here somewhere about circulating air under neath the belly by running the furnace fan, even when the furnace isn't fired up. How is this accomplished? I have tried moving the fan mode on the thermostat to on, instead of auto, but it still doesn't turn on. I have also tried turning the heat/cool switch to off, and the fan to on, which does turn the ac fan on, but that doesn't seem like that would circulate through the underbelly. How does one turn the furnace fan on, while the furnace is off? I am wanting to circulate some of my "electric" heated air under there.

When I winter camp.....I have a radiant heater I put in the basement.

If you turn the thermostat in the bedroom to run....it will work. It doesn't work on mine on the main thermostat

I tried the bedroom, and it blows though the ac vent, also. I can't get the furnace fan to run, without the furnace kicked on, and burning.

Hmmm, that's a good question. A always assumed like Dave said that if you select fan on, the furnace fan will come on, but now I think all that comes on is the AC fan.

^It would be nice to have the furnace fan on, to circulate warm air through the belly. I haven't been to get the furnace fan to come on, except when it's fired up. This is the first time I have ever tried this, on any RV, but it seems like it would help heat the underbelly, with warm air from the living area.

If you don't have heat pumps the only heat option you have is in the living room. The propane heater only circulates air when it's heating and for just a few minutes after it shuts off to cool down the heat exchanger.

Jerry,
When you turn the fan switch to on in the living room, what fans comes on?

(I hate being in storage for the winter )

The ac fan. I have to put the heat/cool switch to off position and the fan switch to on, on the thermostat, to get any fan to come on, and it is the ac fan. I have not been able turn the thermostat to any setting that will get the furnace fan on, without the furnace "fired". Same results on the BR stat.

I've done all this. Can't be done. Something that they need to change in my opinion. Unless the furnace is ON, then the fan that circulates in the underbelly will not run. It's not like this in our other RV. You CAN turn the fan on without turning on the furnace. We are going to put a heater in the basement.

^ I probably will also, but any electric heater I can't see, I don't seem to be able to trust.
