Just brought home , stopped a few days at koa everything works, but I could not get the furnace to kick on, thermostat klicked box under sink area, but did not start , any help on this , thanks

From the sound of it you have 12 volts going to the furnace that is why you hear the kliking sound. The 12 volts come from the furnace to the thermostat and returns to the funace to run the blower motor. Since the blower motor is not running it could be a frozen motor for the blower. You will need to remove the furnace core and check the blower motor and the wiring from the input connector to the blower motor through the sail switch and overheat switch to the control board.

I found that with a very low battery my furnace did the same thing. Hows your battery?

Batts r good, and was plugged in @ KOA , is there a vent off the furnace like a house ? thanks

[Bluto]

Usually chrome, one hole is intake and one hole is exhaust. Look right out side of where the furnace is located, on the side wall of the trailer.

I dont know if you got it fixed yet, but I have a 1989 36ft land yatch 5th wheel and my furnace did the same thing. I would come on and try to ignite but just wouldnt. So I took the burner out and the the burner pan, was all rusty. Its the part with all the holes in it, kinda has a triangle shape to it. I replaced it, $34.00 and now it works like a champ.

Thanks, I found dirt dobbers in the furnace, vents or the rv place did, furnace works great, they told me they got 3 hand fulls out of vents, needless to say I now have vents covered.
