Dometic RM1350M Refrig w ice maker not working on lp gas

[Tgagel]

I need some help please. My rv is a 2017 Forester. The frig works great on electric. Ice machine makes ice and both compartments are cold as they should be. When I turn on the lp feature only the freezer compartment is cold. The fresh food compartment does not cool at all. I can see the gas burner ignite and run which I guess is why the freezer gets cold. Cant figure out what is up with the fresh section?

It could be low gas pressure to the unit. Or a partially blocked orifice.

Here's the Service Manual for the unit. Look on page 4 and it lists things to check when gas mode isn't cooling as it should.

I would check the condition/position of the flue baffle per page 32 of the manual Bama Rambler posted.

Here's what it says....
8.5 Flue Baffle
The slots in the burner should be directly below the flue
tube. The burner should be cleaned periodically, at least
once a year. Soak the burner in an alcohol based solvent
and allow to air dry. If the burner does not have a
good ground it can/will cause erratic gas operation. The
electrode should spark to the burner not the flue tube or
thermocouple.
The flue baffle (spiral baffle) is a twisted piece of metal
that hangs in the flue tube to slow the heat from the flame
to the proper location on the cooling unit. If the flue baffle
is too high or low the heat will not be transferred to the
cooling unit properly. Low cooling on gas operation.

Lack of heat transfer to the cooling unit will cause low cooling
performance in the gas mode. It should be cleaned
periodically, at least once a year. The proper length and
position of the baffle above the burner should be as shown
in the chart.
