Ruined my Refrigerator Burner
I have a Dometic Servel S620 refrigerator. The burner flame was sputtering and while attempting to clean it I altered the dimension of the orifice in the burner tube. (0958164006) I have looked high ...

I wanted to provide an update to this thread since I was the original poster. Original problem was a stuttering refrigerator burner flame. I took off the burner assembly LP lines and cutoff solenoid and cleaned each of them thoroughly as well as the burner flue. I then replaced the burner orifice and the igniter/thermocouple on the refrigerator with new parts, added a new copper washer and checked the connections for any leaks. When I powered up the refrigerator the flame was still sputtering as before. :?
The burner tube has a hole on each side about 3/16” in circumference which provides the proper amount of air for the flame. There is no adjustment to allow you to adjust the air volume. On a lark I plugged one of the holes and the flame immediately stabilized and looked normal. So I am theorizing the sputtering appears to be an air/fuel mixture issue. My initial thought was just to use some metal tape to cover one of the holes and call it a day. However, I am wondering what changed.:h
The amount of LP used is regulated by the main pressure regulator mounted on the LP tank. It is supposed to provide 11” of Water Column. I am leaning towards the regulator malfunctioning or a leak somewhere allowing LP to escape. The stove, furnace and water heater all work flawlessly but they use a great deal more LP than the miniscule amount the refrigerator uses. My next step is to construct a homemade manometer to measure the water column present at the fridge. This should identify whether the LP pressure is an issue or not. Could mean I just need to adjust or replace the regulator.
I’ll update this post once I have measured the water column.
