The refrigerator was leaking water from the freezer section.

First remove all food from the freezer section, disconnect the power to the refrigerator and then remove all the shelves in the freezer.

Then remove the back panel inside the freezer by taking out the screws holding it in and then simply lifting it out. A Philips screwdriver and 1/4" driver was needed.

After the panel is removed, you can see the defrost heater screwed to the refrigerator coils. It's in two sections wired together. One section is screwed to the bottom of the coil and the top section is screwed half way up the coils.

Unplug the wires and thermostat (coming from the defrost heater) from the wire assembly located above the coils.

Next, remove the screws holding the old defrost heater (there are two screws for each element of the defroster)and lift the heater out. Pay close attention as to how the old heater is situated in the freezer in order to put the new one in the same way.

Attach the new heater by putting the bottom element on first and replacing the two screws to secure it. Be careful to keep the wires from tangling and attach the top element the same way.

Next, carefully connect the wires and thermostat from the heater back to the wire assembly the same way they were connected from the old defrost heater.

Place the panel back in place in the back of the freezer section, replace the shelves, and connect the power. You're finished!!

P.S. Don't forget to put the food back in the freezer.
