Hi all. My freezer don't work. Inside stays warm, no hint of coolness on the elements. Outside stays warm, no real hint of warmth on the elements. THe funny big ball thing at the bottom which I assume has some sort of motor in it, and the two sets of elements go in to, is red hot. It buzzes loudly for a few minutes to start with then goes quiet. Any ideas or should I just "mag to grid"?
