The refrigerator was not getting cold and the coils were not defrosting.

Start by removing the freezer door and inner baskets so you have some space. Next, take out the ice maker by removing the 3 screws that attach it to the side and unplug it from the harness. Then the cover for the thermistor and the fan vent should be popped off carefully leaving the back cover only. The back cover is held on by 4 screws, one in each corner. Remove all 4 screws and carefully loosen the back cover by pulling the top forward and laying it level to pull it out. Behind the cover are the coils and other components. If the coils are covered with ice they should be defrosted by using a blow dryer. Once the ice is clear, the thermostat is located towards the top left clamped onto a copper pipe that circles up and around. Carefully pull it off the pipe and cut the wires making sure you leave enough to reattach the new ones with a butt connector. Strip about 1/4 inch of insulation off the wires and crimp both ends into the butt connector making sure they are tight. Heat shrink is highly recommended. Clamp the new thermostat to the copper pipe where the old one used to be and your almost done. Replace the back cover the opposite of the way it was pulled out by putting it in flat with the bottom part in front. Once it is all the way to where it needs to be, push the top upwards while sliding the bottom downwards, then push it in flat against the back. It can be bent slightly if needed. Put the screws back in that hold it on and replace the plastic covers. Then reinstall the ice maker being sure the hose for the water is correctly positioned so that the water goes into the ice maker. Turn it back on and put the baskets and door back on and you're done.

Freezer cold, refrigerator warm

Overload relay accessible from back, by compressor unit. Very easy to change out. Diagram from your site placed defrost thermostat in same area.It wasn't. Found another diagram, showed it in refrigerator light area, took that apart, not there. Yet another diagram showed it in the duct work area at back of refrigerator cabinet. Not there. Finally removed back of freezer compartment, found thermistor and thermostat with the fins. Clipped wires, wired in parts, quick fix. Longest amount of time was spent finding the old parts to replace them. Actual replacement took less than 15 minutes. Refrigerator holding at 35 degrees set on 2 now, better than ever. Total cost, less than $120, doing iy ourselves....priceless.
