Furnace trouble again .....
I don't know what I did wrong this time .... So back to the 1999 28-T Bounder. I put a new furnace in last year ... second time I did this .. SUBURBAN FURNACE SF-35 I had also found the safe...

I completely agree but .....
My problem is this is a 20 year old unit and the problem just started after I changed out the regulator.
My "feeling" was the old regulator was not supplying enough fuel ... the burner sounder like it was pulsing (whoosh ...whoosh ... whoosh) ...
It now sounds much more steady of a flame.
I have not changed any of the duct work in the RV and I checked to see if it was blocked ... it is not.
I did check the outside vents ... I installed a bug screen over them years ago ... even blew air down it .... seems fine.
I bought the unit 10 years ago and we lived full time in it for 3 years while we built a house (not fun here in Vermont).
One thing I did notice ... the factory cut a new hole in the furnace housing to install the ducts. Rather then use the factory cut outs, they cut out the top of the furnace.
It just always seemed odd to me as there is now way for the air to pass by the back of the exchanger ... the blower sends it over the top and out. If the air was exiting the back, it might coll the switch better.
As I said, I have had this unit for 10 years and it has never been a problem before but by putting on a new regulator and possibly putting out more heat, could I have discovered a problem that has been there all along?
Any suggestions on how to fix the problem would be greatly appreciated!
Thanks again .... Mike
