I was able to use the videos on this site to verify the problem I was having. The temperature sensor was in fact the older style sensor. Once the sensor was replaced, and the freezer was manually defrosted, it has been working great since. The freezer would usually last about two weeks before I would have to remove everything and defrost it. We are going to move and I did not want to continue this headache at our new place any longer. Our fridge is in near new condition after a few years and did not feel that spending $,$$$ was worth it. I was laughing at myself for not doing this months ago, it was so easy.
