My freezer was working, but the fridge was warm.

After doing some research, I found that this problem is due to a defrost issue, and the easiest way to make sure you get it fixed is by replacing the defrost timer, defrost heaters, and defrost thermostat. The defrost timer is in the compartment in the fridge on the top level, behind the temperature settings panel. The defrost heaters were behind the back panel in the freezer section, and are long glass tubes that are only attached by a couple screws. When you buy the parts, dont buy the heaters and a defrost thermostat seperately, because the heaters come with a new defrost thermostat already wired to them. Once you get the back panel off, its pretty self explanatory how to remove the heaters.

Freezer wasn't keeping food frozen

First I turned the freezer off and took out all of the shelves in the freezer section. I then removed the guides that the shelves go into. I removed these only from one side of the freezer - the left side actually. Now I removed the plastic piece that keeps the bulb in the freezer protected. Removed the bulb. Removed the three screws on the top and the two in the bottom that keep the rear panel of the freezer attached. This exposed the header cable and the coils. The coils had ice on the lower section, I used a hair dryer to melt the ice. Removed the cable assembly that has the two heater elements and the thermostat. The thermostat had to be plucked off the the metal pipe of coils. Replaced the assembly with the purchased assembly. Clipped the thermostat onto the metal pipe of the coils. COnnected the wires at the white connector. Attached the real panel using the five screws, put the bulb back in, installed the bulb cover, installed the shelf guides, put the shelves back in.

Freezer freezes very well now.

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.

De light flasing on freezer door electronic disply

I removed the back wall panel inside the freezer compartment(approx. 6 screws). The coils were very iced up. I manually defrosted the the coils with a hand hair dryer. I then removed the 2 screws from each heater element and the clip-on thermostat from the coil. I pulled the elements, thermostat and wiring harness(item 230 on parts diagram) out of the freezer compartment and installed the new assembly. Electronic self-check of the defroster indicated normal. Further checks indicated the lower heating element was open.
