furnace problem

[shasta21]

My Rv has an attwood 8500-Iv furnace it turns on ,the blower and every thing and I hear some clicking noises at first but it just does not fire ,I'm trying to sell it to buy a different camper , anything I can try?

If the batteries are low the furnace will do everything except light the burner. I would plug the rv in and then try. It will get all the juice it needs to work. Just another thought.

What filter?

T-stat contacts make up........fan comes on then spark electrode fires to ignite main gas......

BUT yours is NOT lighting main gas.
Various causes from voltage to bad board


Light off ALL stove top burners on high to get propane flowing and place a demand on regulator.
If flames are steady, strong then pressure is OK
If flames fluctuate and diminish with them all on then regulator is not maintaining proper pressure and needs adjusting.

IF flames are steady...try furnace a couple times to make sure problem is not just lack of propane flow
If it still doesn't light off.......start with a good cleaning of burner assembly and check of spark electrode.

here is a service manual that includes your model.........pg. 30 outlines causes/solutions LINK

Its summer time , worry about the furnace later, enjoy camping today .

Give it a good cleaning--exhaust, intake, burner tube, flame sensor, sail switch blade, circuit board connections, and orifices.

Do any of the other Propane appliances work? Stove? Hot Water?
