i had such high expectations for this refrigerator. it has so many wonderful features and looks great.
unfortunately, the one feature it's lacking is the ability to keep food cold!
over one week, there was never a 24 hour period where it actually maintained a constant 40° or less temperature. i used wi-fi thermometers to track the temperature.
we followed all the suggestions, including keeping it 2/3 full, plenty of air circulation around the outside, and all the vents clear the temperature would randomly go up for no explainable reason; it was often over 40° for hours; then decrease to below 34°. no one opened the door, the power was constant, and we keep our house cool.
luckily, we discovered this issue within the first week; we are returning it to samsung for a full refund.
