I have a ZUF 105 Freezer and I have the same problem of the red warning light coming on and when pressing the superfreeze button it goes away. The freezer makes a loud clicking sound as well every now and again. We removed the freezer compartments and the back inside panel on the lower left has expanded out so that the 3rd drawer does not goes back nto its place properly. Is this because there is Ice build up at the back of the freezer or do you know of any other problems with this freezer.
