I have tried the other fixes.....
Mine is a fairly recent manufactured refrigerator.
The gas heater assembly is at the bottom right and the burner is on the right side in the flue assembly that goes vertically up the right side. The layout is: gas line goes to the gas control valve with wires to the right of center of the refrig. Then the gas orfice which has a small opening the gas comes out of, air gap in the tube then the horizontal tube running into the flue.
Here are the steps I used:
1. Turn the refrigerator off.
2. Open access door behind refrigerator.
3. remove 3 screws and take off wind shield at flue on the right. You may or may not have this or need to take this off.
4. Using a can of computer air spray (heavy duty $4.95 at Walmart in the electronics dept.) insert the plastic spray tube into the air gap pointing toward the flue and spray air. Do this until you quit getting dirt and debris out.
5. Turn the refrigerator on LP gas setting.
6. Look at and listen to the burner. It should have the same "roar" as the water heater makes when it is on. If dark, you can see the glow of the burner running in the flue. Don't spray the air into the flue while the burner is running or you will get flame out the sides and bottom. Don't ask.
7. Screw the burner wind screen back on and close the access door.
If blowing out the flue does not fix it, the next step is to remove the orfice and soak it in solvent. Do not try to use a piece of wire to clean it out. I have read that some units have a synthetic sapphire with fine hole in the center to control the flow and you can break that off with a wire.
