RV Make: Damon, RV Model: 4096, RV Year: 2004, Brand: Atwood furnace, Model Number: 8940-iii-dclp. November 18th, 2020. I have just perched a 2004 Damon 4096 motorhome.

and the burner ignites but it won't stay lit. It 'attempts' to light the
burner several times even though it is actually lit and then it just shuts
down the gas (propane) and the blower continues to run (until we freeze to
death, turn it off, or the battery runs down).
According to Atwood's web site there are many things that can cause this
problem including low gas pressure, bad circuit board, bad flame sensor, too
much static pressure, not enough static pressure, bad wires, loose blower
wheel etc. I found that the blower housing had a missing screw which would
cause low static pressure. I replaced the screw and the furnace worked
fine--for a while. Then it started doing it's thing again.
I have not tested the circuit board, the gas pressure, or the static
pressure as of yet mainly because getting all of the needed equipment to do
this would probably cost as much as a new furnace. I have checked the sail
switch, checked the exhaust for obstructions, checked for loose connections
etc.
I would like to know before I yank the thing out and take it apart if there
is a common problem with these furnaces that can cause this particular
problem. I found an aftermarket circuit board but it costs $150 and it says
that after two failed attempts to light the furnace it shuts down
permanantly. Sound rather final. Also sounds like maybe you need to buy
another $150 board if it shuts down. But at least it doesn't keep the
blower running ;-)
Thanks
