Most likely came to Forest River's attention due to owner complaints to dealers...."Hey my furnace won't lite, doesn't run"

huh?

are you thinking they mounted the furnace up to the exterior wall, but didn't cut in the vent? Maybe that would do what you are saying, but otherwise if it had enough room to exhaust inside its a HUGE health issue - more like death issue.

Exactly what happened.

Dealer caught it.
No Furnace vent on exterior wall (inlet/exhaust).
Thought furnace hadn't been installed. Removed return air vent and there was a furnace BUT vent assembly in exterior wall had not been cut-out/installed.

One (1) affected unit but 200 on recall.
Furnace wasn't operated BUT odds are it would NOT have functioned it attempts had been made.
Insufficient combustion intake air/high exhaust air pressure---no main flame and IF it did lite off......High Temp Switch would have tripped it due to High Heat Exchanger Temps due to obstructed air flow.

RV Furnaces have a very narrow air/fuel ratio.
Blocked duct work can cause shut down/not operate
Blocked return can cause shut down/not operate
Blocked combustion/exhaust etc.
Loose air wheel etc.
Low motor speed etc.

Fact is-----It's a wonder they work :B
