Just wanted to say thanks again for this info.
I have fine tuned my temp and it is holding great now. I wanted to change the temp a few degrees and tried with the large dial knob that lets you fine tune it when the freezer is operating normally, however I got large temp swings and couldn't get the temp I wanted. I then tried adjusting the temp by only turning the course adjust screw you mentioned and can set the temp perfectly. So if anyone else is having problems don't touch the large dial and only use the course adjust screw. My screw works out to be about 2 degrees warmer for every one full turn clockwise (screw in).
