Customer Questions and Answers for Refrigerator Temperature Sensor by Ge

Addison, You will want to check to see if the evaporator fan motor in the freezer is working. If it is not then most likely the fan motor is burnt out and would need to be replaced. If it is working then you will want to check to see if there is frost building on the rear wall. If so then you can check the defrost limiter to see if it has continuity. If it does not have continuity then you would not need to change it out. You will also want to check the defrost thermistor for resistance. The resistance values should be as follows, 42.5K at 0 degrees, 14.4k at 37 degrees and 5K ohms at 77 degrees. If not within range then it would need to be replaced. If it checks good then also check the defrost heater for continuity. If no continuity then replace and if good with continuity and all other components check ok then you would need a new main control board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
