My unit was not defrosting. Defrost heater was not functioning. Defrost heater tested good with a meter. Thermostat (cold) tested bad with a meter. Defrost timer was working properly. I replaced the thermostat but I had to buy red crimp connectors because the blue ones that came with the thermostat are designed for wire bigger than 18 AWG wire. The thermostat leads as well as the wire in my unit were 18 AWG. The crimp was not tight enough for my liking with the blue butt connectors. I also purchased smaller heat shrink tubing. After replacement, the defrost heater started working. I could see it glowing. Unfortunately immediately after getting the heater working the contacts in the defrost timer arced and stuck together thus preventing the timer from exiting defrost mode. The heater went off at this point indicating that the thermostat was now working. I then purchased and replaced the defrost timer and now the fridge is functioning properly. I noticed both replacement parts, even though I looked up my fridge model, were different part numbers than the originals. I'm guessing the new parts are improved? I also noticed the timer was an 8/30 rather than a 10/30 like the original. The fridge is working better than when it was new so evidently defrosting every 8 as opposed to every 10 hours is better for my unit.

Long story short:

Buy the correct crimp/butt connectors before beginning replacement of the thermostat and proactively replace the defrost timer since it is rather inexpensive.
