Advanced search is your friend. It will let you expand the search range beyond the 6 month default.
That being said, there are several factors.

What is the ambient temperature?
Is the sun shining on the wall where the refrigerator is located?
Have you checked and cleaned the burner and orifice?
Is the flame audible? There should be enough propane flowing that you can hear the flame when standing beside the lower vent. If it is quiet, then it is possible that the orifice is partly plugged or there is an oily residue build-up in the propane lines.
Do other propane operated appliances have a good flame? Even if they do, the lower gas flow for the refrigerator still might mean that the line needs to be blown out.

To blow out, shut off the gas. Disconnect the line at the refrigerator and the regulator. Place the end of the line from the regulator in a bucket or something similar. Use air pressure to blow out the line from the refrigerator end. If the oily gunk is the problem, you will see it in the bucket. Reconnect the lines after cleaning the burner and orifice (don't poke anything in the orifice opening. Just use rubbing or denatured alcohol). Turn on the gas and test the connections for leaks. Purge the lines by turning on the stove until it lights and burns steadily. Then try to turn on the refrigerator. It may take a number of attempts to purge the branch leading to the refrigerator before it finally lights and stays lit.

Let it run and check to see if this fixed the problem.

+1  Excellent advice from StephenH.  Also: If you have oily residue come out of the regulator (when taking the outgoing line off) you will need to replace the regulator - fortunately they are reasonable in price at around $15.  Lastly to improve the cooling ability of your Dometic take your muffin fans and re-locate them under the top set of cooling coils.  Also re-locate the bi-metal switch that is usually located between the 6th - 8th cooling fins and put it within 2" of the chimney cooling stack.  The switch can easily be located by looking for the 2 red wires that lead to it.  By locating it close to the stack the switch will activate sooner and run the fans longer - resulting in colder fridge temps.
