Just a status update. I called the closest Airstream dealer. And the service technician told me the weirdest thing. In all his 15 years of working on Airstreams. He ran into an issue where the fridge wouldn't cool. He said that he had to leave the door open and heat the fridge. Once he did that it started to cool. I tried a similar setup, I place a hot cup of water inside the fridge, with thermistor on it. Sure enough the freezer had a ton of frost on it. And the Fridge was reading 48 on the outside screen.
So I tried to duplicate the effect without the hot water, but I can't seem to get it to cool. So I thought it was maybe the thermistor. So I ordered the Snip-The-Tip dealio. Just installed yesterday. I'm crossing my fingers, I must say the ambient temp is pretty cold out, not sure if that has an effect on it or not. And the fridge is completely empty, haven't put anything in it. If this doesn't work I'm taking it to a camping world or something at the end of the week.
