Further on the GTS22WC problem....

The GE refridgerators are known for bad mother boards (or circuit boards). The relay gets carbon tracking and causes arcing until it finally burns out. I am a mechanical engineer and I work with an electrical engineer. Our GE fridges went out in the same week. A place called appliance parts pros dot com had our parts in stock and we could order through the net on their website. The part is roughly 150.00 including shipping. By the way, your unit started working again because the relay is making contact temporarily. It will fail again.
