Refrigerator does not maintain consistent temperature. Purchased digital and analog thermometer that shows temp out of FDA safe temperature over 41 degrees. Samsung collects data over multiple days/hours and says we are leaving door open too long. This is not true. Samsung was unable to break data down by occurrence to  tell us how long door was open per occurrence. There has been no action by Samsung to help with this. Food gets warm and spoiled and have to throw out. 
Freezer works well, ice maker is good, and I love the beverage center. Super disappointed with refrigeration. My 22 year old refrigerator works better! Still hoping Samsung makes this right! 3rd Ticket is still open.
