Jim S for Model Number RF260BEAESR/AA-0001 I think I have an issue with the defrost system. Once or twice a day the inside rear wall gets hot to the touch and the compressor and condenser fan won't start. Then when the fridge hits about 60F inside, the comp starts and the fridge begins to cool. At the same time, whatever is heating the rear wall stops and it begins to cool. Seems to only affect the fridge. I have pulled the internal cover over the evap and confirmed that there is no ice and that the fan is working. Condenser coils are clean. Condenser fan runs, except for when it is in this defrost mode or whatever is heating up. What I could find online, seems to point towards main board failure.
Answer Jim, You will want to remove the rear wall of the refrigerator and check the defrost sensor to make sure that it is good. It sounds like the sensor is not reading properly and causing the rise of temperature if it is staying in defrost for more than 1/2 hour. If it is only about 30 minutes then the issue will be normal. If the sensor checks ok and it lasting longer than 30 minutes then the issue would be in the control board. Read More... Answered by AppliancePartsPros.com | Friday, September 11, 2015
