The most telling symptom was the hot cross bar between the refrigerator and freezer. The fix isn't difficult but definitely annoying. The fan is fitting over the condenser. The only way to remove/install is safety is to slide the condenser out. This is done by removing 1 screw at the opposite end. Sounds easy, right? Not! Very hard to get into the tight space. Had to remove the ice maker water supply (also 1 screw) to access condensor screw. Once you move the condenser, a little elbow grease and the fan came out. After that, plug in the new fan, slide it back in and reattached the condenser and ice maker supply. Not bad but annoying.
