Steven S Westminster , CO March 25, 2017 Appliance: Model GE GSS25LGPA BB Fresh food side was freezing and could not adjust. First, I replaced both thermasters. No change. I then replaced main circuit board, which solved the problem. I noticed a burn mark on a solder joint on the defective board. Replacing the board was very simple.
