The temperature is good at both top and lower but the fan comes on at odd times (sometimes when the compressor is on) but, I am unable to pull-out the refrigerator to tell exactly where it is coming from. It seems to be coming from the center of the appliance but, I could be wrong. I just cannot tell at this time.
We pulled-out the refrigerator and removed the back panel where the compressor fan is and discovered that it was not the problem, as everything was working properly. However, while we were behind the appliance, the freezer fan came-on and it was the one producing the noise.
Thank you! I will have to try that when I get off work tonight.
