Jon S Tuscarora , MD February 21, 2015 Appliance: Samsung Refrigerator RF260BEAEBC/AA-0001 Samsung Refrigerator Rf260beaebc/Aa-0001: Displayed e1 error code the root cause was the sensor (thermistor) that got ripped off of the roof of the freezer. How to replace Refrigerator Temperature Sensor. 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. 72 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
