My freezer works great but my refrigerator is warm. There is no air moving through the damper to get the refrigerator cold. I do not understand what could be happening. The evaporator fan motor is running fine. What other component could there be for air flow to get into the refrigerator to get it back to temperature. At this point I am ruling out the temperature sensor located in the fridge because that is not what opens and closes the damper or is it? Looks like to me the damper opens when the evaporator fan motor in the freezer comes on. Please help I like GE and do not want to have to buy a different brand refrigerator for a simple fix. Thank you!
The issue with the unit may be a defrost problem. You will want to check for impacted frost on the coils of the evaporator in the freezer. If there is impacted frost 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
