If you are seeing a good blue flame when using the stove top this will tell you your propane tanks is working correctly.
All of the propane furnaces have a safety switch in front of the furnace blower that blows against what they call a SAIL SWITCH. If this switch does not operate properly it will close the propane valve feeding the furnace and shutting it down like you are seeing... This sail switch is mounted in line with the blower duct and could pick up a big bunch of debris etc and may need cleaned up to operate properly...
I always make sure my stove top burners are working good and the 12V DC Furnace fan is blowing good before starting up my propane furnace. About the only thing left to inspect is the SAIL SWITCH action.
The Furnace blower fan does operate from the 12V Battery System so it can be used when you are off-grid somewhere. It will draw around 5-6AMPS DC Current and will run down your battery in one nights of furnace use with no shore power available. Something you need to consider if you are without shore power or generator somewhere...
I also carry a couple of Electric OIL FILLED heaters with us our trips as a plan-B for heat... We will plug an extension cord into the the pedestal 20A Service just to operate the stand alone Electric heater.
Same goes for when camping off grid somewhere. We will use a smaller propane heater like the MR BUDDY series for heat when we are up and awake. When we go to bed we will get under the covers haha. Too dangerous to run a Mr BUDDY heater when you go to sleep. You just might not wake up due to CO poisoning...
I really hate our propane furnace as its blower is way to loud for our small foot print POPUP trailer and it also produces WAY TOO MUCH heat. Runs us completely out of the trailer when it is running hehe... One of these years I want to remove my propane furnace and replace it with a Hot Water HYDRONIC type heater.
