Since I could not find the correct thermistor from the schematic provided, I ordered the thermistor harness for the evaporator. I cut the harness and spliced it to the sheared thermistor wires on the roof of the freezer compartment. It now works fine with a little "farmer ingenuity" help. Samsung was absolutely no help at all, but the guy that I spoke with over the phone at APP sure was. This site is now my "go to" for appliance parts! Tip for others with this model. Do not overfill the upper storage tray in the freezer. Doing so may cause stored items to shear the freezer sensor (thermistor) off when the door is closed.
