We are having the same problem with ice building up on the top of the freezer near the door. Did heating it with the hair dryer work? or did you have to buy a new gasket? I'd rather buy a new gasket than a new fridge but I'm wondering if the door is just misaligned. The floor of my kitchen isn't very even since it's an older home. Any thoughts?

My freezer door all of the sudden will not seal completely on the top.I took the gasket off and flipped it over hoping that would work but it did not. Everything is staying frozen but there are water droplets freezing on the roof of the freezer. It seemed that it was sagging on the opposite side of the hinge so I tried adding another plastic washer hoping that would help but it also did not work. I don't think I need a new door gasket but I don't know what to try next. Anyone have any suggestions? Thanks!
