Angry Furnace Problem

My furnace worked fine when I stored the trailer, but yesterday morning and today it would only run for 15 seconds and blow cold. It wouldn't kick on automatically no matter how high I set the thermostat. I have propane cause the stove fires good with all three burners on high. Thought I'd try the forum before I call the repairman.
Any and all suggestions appreciated.

Make sure you don't have any blocked heat ducts or any wasps nests in the outside flue. Anything that will slow down/block the air flow will prevent the sail switch from allowing the gas valve to open. That's where I would start.

Is your battery fully charged? if not the air flow will not be great enough for the furnace to fire.. Check the propane tip at the furnace spider mites like to build nests in the tip as they like the smell of propane..
