Pay attention to XTeacher. The "probe" he refers to is called a THERMISTOR. I had never heard of such and our refrigerator was turning everything in to a solid block of ice. Turns out the thing I had never heard of had fallen off and the clip was in a beverage tray on the door. Putting the thermistor in and moving it to the correct location in the fins solved the problem without any fuss. Since the thermistor has thin wires connecting it to an electronic plug in, the wires or plug in may be the issue.
