Furnace never turns off
We were camping in Pennsylvania this weekend and had to use the furnace for the first time on our 2014 3171. I had thought that it would turn off after it heated the motorhome but it never did and we let it run most of the night. Is this normal? Even after turning it below room temp it would never turn off.

If your thermostat is like mine you need to set the fan on auto and then set your setting to furnace, your fan will cut in as needed

X2 its not the heater running 24/7 its the circ fan for the A/C. They wire it that way to circulate the air while the heater is online. Use auto fan setting to bypass the cont. signal. The furnace fan only will run. Seems like you'd be cooking by 1am if the furnace continued to fire!

New problem. I can get our furnace to turn on but it eventually stops. The only way I can get it to start again is by pulling the fuse and reinserting. This happens at cold outside temps. Does the furnace not work at very cold conditions

I've been in a unit at 17 degrees Fahrenheit and the furnace worked just fine.

Furnace issue
We traveling in very cold weather and have a furnace issue. The furnace fan will turn on but the furnace does not always lite. The sometimes the furnace does lite but goes off well before the temp is reached. I checked the propane and have 3/4 tank. We also turned on the stove burners and they will light but the flame slowly lowers and eventually goes off.. Any suggestions?

I don't recall the details, but I seem to think something like this happened and it was two different causes.
1. debris or dust in the line caused the regulator valve to freeze up.
2. Something with a check valve to something, They had to turn off the tank, wait a bit and then open it very slowly.
Or I could be recalling the complete wrong thing...but the 2nd one costs nothing to test.

Could be flame sensor dirty. Take steel wool or light sanspaper and clean off any black or corrosion. Rhis also no cost. Id this does it easy replacement and not expensive. 2nd is limit switch make sure ALL heat vents open and nothing blocking airflow. Also make sure filter clean. Sounds more like limit than sensor but might as well check both.

Opps sorry did not read part about stove flame. But never hurts to remind people to check filters.

Admin needs to add a "squirrel finds a nut" emoji. I was reaching back to the inner reaches of my mind. Almost got lost.

There is a way to "reset" the thermostat. We reset ours the first time we used the heat on our 3010 but that was two years ago and unfortunately I don't remember the sequence, perhaps someone could help out.
