So I had an independent tech come out and he agreed that it smelled like Freon and noted that it was a closed system issue, had to have Samsung come out so it would be covered under the 5 year warranty. Samsung tech agreed that it smelled like Freon, called his supervisor who told him (without seeing anything) it can't be because the unit is still cooling. He checked the frost pattern and said there was one but not over the whole thing. He didn't check the freezer. Tech installed a new ice maker and left. He said if it's refrigerant we would smell kit again when the it gets cool. Unit started cooling and was at 45 degrees, then I checked again and it was 64, then I hit power cool again and it finally made back to the set temp of 37. Opened the middle drawer and I smelled it again. ANy ideas what I have going on?
