If your refrigerator or freezer is too warm, or making noises, you may need to replace the fan blade. The fan blade attaches to the evaporator motor, which is in the freezer section, to help circulate the cold air into the refrigerator and freezer sections. The fan blade is white in color and made from plastic. This is a genuine OEM part. Please be sure to disconnect the power to your refrigerator before starting your repair.
