With all due respect that is 100% factually incorrect. There is absolutely no logic in these, nor has there ever been, to vary the LP pressure/orifice in any way shape or form. Gas valves are either on or off. Electric elements are either on or off. Period. Same with the water heater, same with the furnace, same with AquaHot, same with Air Conditioners. On... or off.

The thermistor is tied directly to the temperature settings. There are approximately 2 degrees difference in between each setting, 9 being the coldest.

Not to pile on, but this is absolutely correct. My old Norcold 1200 had a standard gas solenoid. Either open or shut. I know this for a fact because I had to work on it once.

Then

It's paradoxical but every 1200 I've worked on reacts the same way. Mine is on setting 2 and it's 34F right now. If I set it to 9 it goes up several degrees. I observed this weird behavior throughout several months of testing? Every 1200 I've worked on does the same thing and many others have observed it as well. What's up with that? Is something broken?

I do remember have a refer back in the Middle Ages that was indeed controlled by adjusting the intensity of the flame. Maybe thermistors had not been invented yet? I don't remember what brand it was.

Make sure the inside fridg light is not staying on. On mine I just lucked into the cure, the freezer worked fine but the frig was in the low 40's. Decided to defrost it first to see if that helped and noticed the lens for the light had a dis colored spot. Turned the unit on pushed the lever for the light switch and the light stayed on. Removed the bulb, problem solved. A10watt bulb adds a lot of heat in that small of a space. On LP or AC I have to back the thermostat down one setting from max or the frig will freeze. Good luck with what has been more then a frustrating chase.

Thanks - wish it was that but I have checked and the light is going out. I'm looking into the condensate drain line. I've heard/read that if it isn't routed right, i.e using a P-Trap or plug of sorts it can allow hot air to egress into the fridge and raise the temp up to 9 degrees. I know mine does not have a stopper or a P trap but it sits flush in the bottom of the drain cup, not certain if this is an issue or not but when I am back at the RV this weekend I am going to pinch it off and see if it has any affect.

My 1200 norcold cools best at the #6 setting any higher and the fride temp goes up. I don't know why but I beleive it has somthing to do with the out side air being too warm to cool the coils properly on a warm day.

You are not the only person who has stated this. Logically it makes no sense however when multiple people indicate the same thing it seems there must be something to it.

Thank you.

UPDATE: Was able to spend the weekend at our RV. Upon our arrival the Freezer was showing 2 degrees and fridge 40. I replaced the "Snip the Tip" Thermistor with a standard Norcold model at about 11 PM. When I woke up the fridge was the same. Located a Styrofoam cup and placed a piece between the thermistor and the fin (MuddyPaws Mod), freezer went to 0 and fridge 38.5 - this in temperatures of 110 - 115 in the shade and the fridge is exposed to the sun for part of the day. My cooling fans including the extra units I placed in the roof vent previously ran most of the day which tells me the upper evaporator fins where the snap disk is located, were at 130 degrees most of the day. The fin temp in the refrigerator measured with an RF temp gauge was showing 28 degrees. I was happy with these results in these conditions.

Thank you to MuddyPaws and David Force for their knowledge and assistance while I was working to resolve my issues!!
