I purchased a Samsung French Door with bottom Refrigerator March 2016. I've had many issues including the same thing your mentioning. I've been in the food business for 45 years and know that refrigerated foods must be maintain under 40 degrees. Over 40 Degrees it enters the "temperature danger zone." Items like Milk can spoil before expiration date if kept over 40 degrees. Milk is a good monitor if your refrigerator is working correctly. I have mine set at 34 degrees (coldest setting) and I can get 39 degrees after being closed all night. When I set at Samsungs recommended setting (37 degrees) everything is 43-44 degrees. Even set at 34 degrees, the milk struggles to get to 40 degrees during the day. Also, the temperature varies greatly throughout the unit. I've had sensors changed out and currently dealing directly with samsung trying to get the unit replaced. Samsung needs to stick with making TV's. Also, my bottom freezer has frozen completely twice.
