Removed refrigerator panel, disconnected light and fan power. Removed fan assembly and replaced motor, grommets and fan attachment spring. Unit had adhesive on spring to help hold the spring. Chatted with customer service and clarified that spring and fan would easily pull off motor shaft. Adhesive probably was extra measure used during original build of the fridge.
Noise was due to fan rubbing on housing. New fan position set to avoid any rubbing.
