Hi, I have an STM5200WA Fridge / Freezer. For some reason the 'opening" side of the freezer door has dropped about 2-3 mm. Despite replacing the door seal, cold air from the freezer is escaping when the door is closed. It also means that the roof of the freezer near the door is icing up. It would seem the simple answer is to "lift one side of the freezer door but there does not seem to be any adjustment at either the upper or lower door hinges to do this. Any ideas? Neil
