Thanks Mich. The kiln's empty right now and I'm going to tip it over and fill the space where the compressor was with packing "peanuts" and seal them in. The door seal seams look OK (magnetic) seal all around and clean. The door insulation is thin and I'm adding an extra inch inside. Deluxe Bob suggested extra insulation and I resisted because it's ugly but may have to do it anyway. I have to get it done cause I have two more loads to do and it's getting colder..John, consider drilling holes half way through into the body of the freezer and using The Great Stuff expanding foam to fill the exterior void to help with insulation. As for the humidity make sure that the rubber seal around the door is not too cracked/worn and make sure the interior shell isn't damaged (this could be a big leak of heat/humidity)
