Refrig problem?

[Frankm2]

We have a 2014 tt with a dometic refrig. We ran the refrig on electric and propane for a few days each at the house to make sure all was ok. Before our two week vacation, I turned the refrig on using electric the day before vacation. The next morning at 4:30 am I noticed the fan on the refrig was running. I didn't even know they had fans until then. The system smelled hot. I was hoping it was just the new burning off of it. Since then it has been running on propane, but the refrig and fan run all the time, except turning off in the middle of the night.

I purchased a digital temp gauge with remote sensor. The refrig keeps the temp between 47 (morning) and 53 (evening). I noticed the refrig and fan shut off this morning when the temp in the frig hit 45 degrees.

It appears there is a problem with the frig. My old tt did not have any trouble keeping the temp in the upper thirties. This frig does not have buttons to adjust the temp from cold to colder. Seems like I read something about it being a smart refrig.

Any thoughts?

Inside the frig, right side on the coldsink, is there a little plastic sleeve that has a cable dropping down from it? If so that is the thermal couple that regulates temp. Slide it all the way to the top.
