I have my Freezer set to -1F and refrigerator set to 35F. I have been monitoring the temp as one day last week the freezer got warm and stuff began to thaw. I pulled everything out to check for ice on the evaporator didn't find much. I defrosted and put everything back together. I have been monitoring the temp on both. My Refrigerator has been fluctuating between 46F and 34F and my Freezer has been going from -11F to +11F.
