Ok, I found it. You are partly right. THe molex connector is int he fridge side. THe sensor is in the freezer and goes through a small hole. You will need to remove the freezer top air duct and the top false panel. It looks like there is a fridge thermistor and a freezer one. Getting ready to go test the freezer one. Here are 2 pics. One of the fridge side and one of the freezer. On the fridge side you can see where I disconnected it and ready to pull back from the freezer side. Wish me luck bclinton attached the following image(s):

i just got my thermistor today and installed it. the one i got (item 2188819) is in the refrig. take off the panel running along the top left of the refrg inside. you will see the conector. disconnect and install. there is a little temp probe at the end that sits exposed next to the air duct in the refrig top left. this must read the refrig temp only. maybe i ordered the wrong one. is there one of these for the freezer?

Ok, I found it. Here are 2 pics. One from the fridge side and one from the freezer side. There are 2 thermistors. One on each side. Both of mine checked out ok so I guess I need a control board. TO get to it you need to remove the freezer air duct and a couple of shelves to remove the false air duct panel. The sensor end of the thermistor is passed through a hole from the fridge side and rests in the shelf rail. You cant miss it. Its goes in to the top of the right rail. Remove 2 screws from the fridge side for the main dict top left and if you want to test the fridge thermistor remove the plastic wire cover. I would test it without pulling it through the hole. It might be hard getting it pushed back through. bclinton attached the following image(s):

I believe it is the same. Not positive though. My guess is most of the time the control board is to blame. Theres not much to the thermistor.

I should test my freezer side. How exactly do you test it to make sure it works? Any easy instructions would help as I never tested one before

I used an Ohm meter. I set my meter at 20K setting. One probe in one side of the molex connector and one in the other. Make sure it doesnt touch your skin or it might throw it off. At 32 degrees my meter reads about 12k. That appears to be my problem. Gene - if you are reading this would agree that is a pretty good assessment?

To confirm. I just disconnect the plastic clip and stick the probes in both holes what reading is good and what us bad. Thank you do much.

Quoting Gene. Mine read about 14k ohms at 32 so it appears to be bad. Basically my freezer seems to never think its at temp so it just runs and runs. Thats why I have been having to Nuke my Ice cream. :)
Gene rocks! I will order my parts from this site.
There is one thermistor in the freezer which is located on top of the evaporator behind the air ducts. You can ohm it out to see if it's good or not. The normal reading suppose to be 10K ohms @ 77°F and 32.5K ohms @ 32°F.
