Robert Z Brooklyn , NY February 18, 2017 Freezer icing on backwall & not cold enough in fridge & freezer Replaced defective freezer fan. It was a very easy job & it now works great. Shut power & carefully defrosted all ice build up behind freezer wall on metal fins with hair dryer & towels & cleared all ice from vents to refrigerator. Nicely dried & cleaned everything. Tested freezer drain hole with very hot water to maker sure it was not clogged & backing up. Installed new fan with the original plastic blade, rubber backing & also replaced the broken air vents. 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
