Unplug the refrigerator. Remove face plate located in the upper back of the refrigerator compartment. Remove face place bracket on the right using nut driver. Removing these screws also frees the metal case enclosing the Defrost Timer. Pull the case away from the back of the refrigerator exposing the Defrost timer. Remove the electrical plug from the Defrost Timer. Then remove the Defrost Timer from the case by removing the two screws securing it. Reverse the procedure to install the new Defrost Timer.
