Product review (5 stars): refrigerator fix
We recently had a power outage due to a storm, and then a power surge when power came back on, many things were damaged including the refrigerator.  My son, an electrical engineer, took the refrigerator apart, found the circulating fan motor (Whirlpool 4389147 motor evaporator) was damaged, we ordered this one from Amazon, he installed it and the refrigerator works fine.  Nice to have access to reliable sources.
