Uh oh. Please see the attached photo. Is this what you (curjones) mean by a partial frost pattern?
So, I may have a leak after all. But where is it coming from?
But as far as the order of cooling goes, I am almost certain that the process in the Samsung is the opposite of what you describe. It cools the Fridge (or BOTH) first, and only then does it switch to the freezer side. I have only rarely seen it (by watching the status monitor) set the 3-way to freezer very rarely and not when I first plug it in. I happened to be monitoring it this afternoon when I saw the status LED change and heard the motor move and then saw the temperature on the freezer side go UP not down. That was puzzling. I then took the cover off and snapped the photo. There is only frost on the top end of the evap coils. The bottom is barely frozen.
