Thanks .....
You guys read my mind (my wife says it is a short story) .... I was planning on heading to the hardware store tomorrow to make a manometer and check the pressure.
So you guys are saying it is "normal" for the high temps switch to cut in and out?
I thought I read on a dealer side (been searching for info all over the web) the unit should run and stay on until it comes up to temperature? The high temp switch is just that ... a safety switch. Or am I wrong?
The RV is 20 years old so for all I know the old regulator may have been failing for years and maybe I just never saw this problem as the furnace has never gotten enough fuel ... or maybe it is getting too much now ... or ????
One thing that always bothered me ... Bounder cut the furnace case and has the lines coming off the top ... not the ends or side where Suburban has holes for it ... it came this way from the factory! I was always wondering if there is the correct air flow over the heat exchange. I would think there is or everyone would have this problem.
Anyway, I guess I will check the pressure first and go from there.
Thanks .... Mike
