This is on a 2002 Dometic RM2353, 3-way
Cools to 20 degrees on electricity, but only to 60 on propane; so I know the issue is not enough heat from propane.
I have 11.31 WC pressure of propane at burner with two range top burners on high. So pressure is not the problem.
Removed, and soaked for a few hours in alcohol both the burner orifice, and burner tube. Then blew compressed air, in direction gas moves, through them both. I can see light through orifice, kind of a pink tint to the light I see.
Nice blue flame, but I don't hear it.
This seems like a good clue.
Tapped on boiler housing, and junk dropped out on burner tube before cleaning.
1. Order new burner orifice and burner tube. Cost $125 shipped.
2. Pull refrigerator and clean burner flue and replace burner baffle (spiral medal part in the flue).
would love to hear your thoughts.
