Replaced the Thermistor Assembly and also picked up Overload Protection circuit per the comments posted by the "experts" on the web site. Both parts cheap enough. I ordered parts at 3:30 in the afternoon and they showed up the next morning from half way across the country. Outstanding service. It also fixed the 9 year old refrigerator. Replacing the parts took about a half hour most of which was moving the unit from the wall and removing the panel to get at the parts.
