Need more info...
Does fan go on when thermostat moved to heated position?
Do you hear the spark inside the furnace which tries to light the propane?
Or
Does nothing, nada happen when thermostat is moved to heated position?

The Thermostat's "FAN" control only controls the Air Conditioning fan; not the heater's.
In order for the heater to work you must have 3 things:
Propane - Valve turned on
12 VDC to the heater (check fuses)
The thermostat set to a higher temperature than ambient temperature.
If you don't have propane - your stove won't light either
If you don't have 12 VDC to the heater (which then supplies the thermostat); your Air Conditioning won't work either.
When things work correctly:
The thermostat tells the heater to turn on
The heater fan turn on which activates a sail switch to tell the heater control board the fan is running
The heater control board opens the electric propane valve to aloow propane to flow and starts trying to ignite it (click, click, click)
If the igniter does not sense a flame with a few seconds the propane valve shuts off and the lighting cycle times and and restarts.
After 3 failed attempts to light the controller goes into an error state and must be reset to try again.
So where are you at in this cycle?

start by taking off the outside cover on the side of your RV, and then push (on/off) the reset button.
Then see if now the fan comes on
if no fan, then it may be a circuit board issue

What thermostat do you have? If its the digital dometic, I have had mine behave very strangely, looking like the AC or Heatpump had failed. Turned out to be a loose connection in the thermostat itself. Just pulling the thermostat face off the mount and reseating solved the problem I had.

When you say 'clean', what do you mean? Never touch the board with anything unless you're really really good with electronics and spark chasing the circuits like the best of them. I cleaned the corrosion off my board once. I wound up replacing it.
Just something shared.

Same thing happened to my ‘16 Vegas 25.2 last winter. I needed to replace the control circuit in the furnace. Cost about $130 at my local repair shop to get it done.

Check with the manufacturer of the furnace. Could be a warranty. But I am sure you would have to have it diagnosed by an authorized dealer. My fifth wheel furnace went out while on a trip to Michigan. The manufacturer paid about 100 bucks on the labor and supplied the board.

We have an axis 24.1 2016
Same issues nothing happens when the thermostat is moved.
It turns out that the original boards were junk. Local RV shop does about one a week.
Replaced the board!! no issues for the past two months..... it runs a fair bit when we use it in this cold Weather!
