I waited 24 hours to plug-in, kept the temperature at setting 4 without anything in the refrigerator and it iced up. Replaced it and it does the same thing. Manufacturer said that I shouldn’t open the door very often - what a stupid and ignorant response as it’s a flipping refrigerator. I hadn’t even put anything in it yet. Wayfair really didn’t help resolve the issue and I’m very disappointed in Wayfair.
