John for Model Number RF28HDEDTSR/AA Good morning. 2 weeks ago the fridge was making a discernible noise. Noise would go away and run fine and quiet for another week. Noise came back and it was at the mid point of the back, not the compressor. I looked on the web and found that the noise was most likely associated with the Evaporator fan motor failing. I am going to buy the replacement part from you since the repair vid you have is great. My question is is there any other parts i should order or just start with the fan. I read some of the postings on your site and some persons replaced the temp sensor and other parts. My fridge does not have any error codes as i don't have the screen on the right door that looks like a laptop. Our fridge is from 2015 I think. Another observation, I did however take off the back panel and saw a processor board. Are there any lights i can read there ? I have a red light but do not know how to decipher it. I'll wait for your reply and any other things i could check before I order the evap fan. The freezer works fine. Its the upper fridge thats NG. Thanks for your input and help in advance. John
Answer John, it is recommended that the evaporator is inspected in the refrigerator section and freezer section to identify if either have become congested with ice around the fan. If there is ice around either fan, it can cause a noise and it will indicate that either the defrost drain is not clearing properly (drain would need to be cleared) or that there is a defrost issue. In the case of a defrost issue, the defrost heater and evaporator thermistor would need to be checked. Testing information can vary depending on the location of the failure. Read More...
