When I first joined here there was a series of threads about replacing bad thermostats, could this be a recurrence?

I agree- but if I were having a problem with something, the first thing that I would do is flip through the book and see what kinds of things that they recommend against that I'm possibly doing. If it takes all of 45 seconds to remove a couple of screens, why not?

We had a similar experience and replaced the chintzy thermostat. We found that by tapping the thermostat it would cause the furnace to work; suspect similar to toggling...

Agree to a certain point, but the open style screens (that are sold by the thousands) could prevent a furnace from staying lighted defies logic. They are a very open mesh.

As I posted before, would like to see some actual hard data supporting this statement in the manuals.

Agree 100% Coot. I would think the Dauber's could and would far more damage than a wire mesh screen.

You're both missing what I'm suggesting- I think that it's a temporary test to see if this is the or part of the problem. If it fixes the issue, then debate putting then back on. If it doesn't fix the issue, you're only out a few minutes of time and effort.

Not at all, it's just such a ridiculous statement saying a screen on the outside of the camper will influence the burner/gas valve functioning properly.

Given that our answer is "RTFM" for so many other things - so I don't know why we would instantly demand "more data" for this one. Suburban wouldn't just randomly add something to their manual, IMO.

As well, I don't think we should instantly dismiss it just because it worked for you for your 130 years of camping.

A screen added to the outside intake/exhaust of the furnace that is designed for it will most likely have little effect on air flow. Add enough contamination to it (dirt, grease lint etc etc) to it and it might reduce air flow enough to affect the sail switch from closing or the over temperature disk in the burner section might open, thus a malfunctinning furnace....

Doug, just stop and think about what they are stating that a pc of screen wire on the outside of the trailer causes a malfunction in an electrically energized gas valve inside the furnace. It defies logic and common sense. Just because Suburban published it doesn't make it fact. Like "it's on the internet, so it has to be true."
