So here it is October and we are getting in our last trip. Needless to say it's a little chilly at night so we turned on our furnace and are having some issues. The fan will run fire a bit blowing cold air then shut off. Any idea on how to get this heat on? We are new and don't have or user manual with us A mistake we won't make again. Thanks for any input!

1st thing to check is make sure the propane tank is full. #2 is make sure you turn it on very slowly. #3 is light the stove to help purge the air out of the lines. #4 It make take several attempts to get it to light the first time.
Do you have inline propane gauges on your tanks ? :Your issue sounds like the exact problem we had one cool morning. Up until that morning I had lots of propane, stove worked, and the fridge worked on propane. When I turned the furnace on, it blew cold and then clicked off, no propane. The month before I had bought 2 propane gauges from Costco and put them on each 30 lb tank, figured this would tell me when one is empty. The gauges have an auto shutoff feature that activates if there is a sudden surge, supposedly signifying a break in the line. I guess the furnace draw was too much for these gauges, so it shut the line down. I removed the gauges, and the problem was fixed. Costco has a great return policy.

Is the fan set to auto or Hi/Lo?
When you turned it off/on did you wait a min or two between off and on?

I have seen several instances where the output of the propane regulator was marginal, and when the temperatures drop (usually at night) the diaphragm in the regulator gets stiff and does not deliver sufficient pressure for high draw items (heater and water heater). The first indication of this problem is when the furnace works when the temperatures are warmer (during the day) and then stops working at night.
A layman test is to light a burner on the stove, and then turn on the furnace and the water heater. As each is turned on, the flame might dip slightly, but should return to its full height.
To actually check the post regulator LP System pressure requires a special low pressure gauge or manometer, and connection of the gauge to the propane line. This is not recommended for anyone not certified to work on LP systems.

Hmmmm I had the same problem with my furnace. The outside temp was in the 40's and it wouldn't heat at all, just blew cold air. I lit the stove and it worked fine and when I tried to turn the furnace on the stove burner would dip down to a very small flame, when the furnace would stop trying to light the stove flame would jump back up. I assumed the igniter wasn't working correctly so the furnace was shutting it self off. I might have a gas flow problem with my regulator instead.
I didn't try to use the gas on the water heater, I was using the electric water heating instead. I also gave up on the furnace after 3 or 4 tries. Should I have kept trying it?
Depends on how full your tanks are, a 20# cylinder at 25% full will only vaporize 18,450 btu at 40 degrees. your furnace is probaly 15-20,000 btu so if your tanks are low you have flow/pressure issues and the furnace "times" out. Fill your tanks
See the attached chart for more info

Crow, you have to be a bit of a detective.
Try the other tank.
Even if you have 2 full tanks it's possible that one of your tank pigtails
(short hose from regulator to tank) is bad.
These hoses have built in check valves and it's fairly common for them
to stick.
Flip your regulator handle to the other tank and close and re-open both
tank valves.
Try to light your stove and furnace again.
If you still get low gas flow it's probably a bad regulator.
I changed both my pigtails and did not solve my low flow problem.
A new regulator fixed it.
Good luck!

My camper had been sitting up for 5 years or so when I bought it last year and there has been a lot of little things to fix. I think the regulator is one of those small things to replace. I will get a new regulator and see how it works.
I had an electric heater with me so it kept the camper fairly warm while I was out deer hunting after Christmas but it takes a long time for it to warm up the camper.

My furnace has never worked quite right. Assuming you have the same ducted furnace I do (or close enough)
There is a reset switch on the right side of my furnce, you can't see it, but it's right beside where a bundle of wires enters the side of the furnace. About dead center middle of the ride side, as you face the furnace from inside the trailer. It's a rocker switch. If I reset the rocker switch the furnace will cycle normally.
Once.
You have to reach your hand way back in there to find the switch, perhaps through a cabinet next to the furnace.

Radio- you say if you reset it, you get one cycle? Does shutting off
the thermostat (not turning it down but rather turning it off) do the
same thing? If so it sounds like you need a control board.
Without knowing your furnace make and model # I'm purely guessing
you need the Dinosaur board called the Fan 50 plus pins.
You can get one from AmericanRVcompany.com
They had the best price I found after much searching. About $95 including
shipping. (Their Ebay price might be more or less than their own
website price. You should check both if you're interested.)
I should have taken the advice early on and just got a new board.
That's what I have now and it works fine.
Very easy install. Replaces the old board perfectly- it's literally "plug and
play".
Good luck!
