Furnace wont turn on

[AndyTobo]

I have a 1998 Jayco 253 RK Eagle 5th wheel.
Long story short, whenever the inside of the camper gets in the 40's, the furnace wont kick on. When I turn the electric heater on, I am able to move the thermostat temp switch and hear it click.
The furnace worked fine all spring, and all of Fall, but now that I want to turn it on to warm it up so I can clean it and winterize it. It is not turning on, it did this same thing last year.
I turned it off, turned it on, moved the temp switch, the Gas is on, and there is gas supplied to it, so that is not an issue.
It is plugged into the house, and the batteries are fully charged as well.
I have had it turned on and nothing for the last hour.

What is my deal here?

You should be able to jump the thermostat to see if that's bad.
Here's a video of doing it from the outside, but should be able to do the same inside.

Just a thought,

Thanks for the video, I went outside to see what I could see, and I walked outside to my furnace running and heat coming out.
I will be watching more of this guys videos.
