I bought this refrigerator for my sister last summer. She is happy with it with one exception. One day she said that the fridge was making a loud noise. Could not figure it out. Then she realized that the freezer was full of ice crystals. She was very upset. I told her it was probably not closed properly.  She denied that at first, but ultimately I was correct.  she made sure it was closed and after a few days the ice crystals went away and she has nor had any problems since.
