Researching the problem I came to AppliancePartsPros.com, which suggested my issue could be a failed Evaporator Motor. I opened up the freezer and accessed the motor, and when I turned the fan by hand, it rotated unevenly and seemed to skip a spot where there should be resistance, making me think it had gone bad. I ordered a new Evaporator Motor from AppliancePartsPros.com and followed your DIY video to install it. As soon as I plugged in the fridge, I heard the new motor come on and could feel cold air being blown once again into the fridge compartment. It took several hours to cool down to the proper temperature. It was a rewarding experience to be able to fix it myself. Thank you!
