My wife found the refrigerator part number finally after I looked for it unsuccessfully. The P/N was found in the side wall only after removing the lower left produce crisper drawer. Anyway...the part was found at appliance parts pros- was sent quickly and directions to install were too easy! Check for icebuild up between the freezer and refrigerator once this was found to be the root cause for the warming temperatures in the refrigerator. With new fan installed no more noise and temp has dropped down to the expected 35 degrees is so.
