I ordered three parts of the Pan chill system for the GE Profile. The "Dial Pan chill" that connects the "Knob Pan Chill" to the Knob piece had broken in two pieces probably due to age and the cold temperatures that it operates in which is attached to the linkage that opens the door to the refrigerator from the freezer so that the refrigerator will cool down. The parts fixed the problem and I now have a freezer at 0 degrees and the refrigerator at 34 degrees.
