Remove the shelving and the rails in your freezer to gain access to the part behind the back panel. Installing this part will require basic hand tools, minor disassembly of the refrigerator and novice repair experience. Remember to unplug the refrigerator or shut off the house circuit breaker for the appliance before installing this part.
