I get a few inches of ice built up in the bottom of the freezer after a few weeks. My freezer is reading -10f and I have it set to 5f. I did the test on the termistor and it coded that it was working. I read that I had to replace the micro computer your part number AP3177964 and my freezer still jumping from -10 to 0 depending on when I check it. It has only been a few days and no ice build up yet but I am expecting it. What temperature should this freezer be?? Any suggestions on what may be wrong. I know the defrost cycle works fine. Thanks for any help.

Did you ever get a response? My Kenmore Elite is doing the same thing.

I do not know what type you have but my problem was fixed with a new themoster for the freezer. It only costs like $5 or so. I would check the temperature in your freezer. My freezer was getting like -20f or so and that is what led up to the ice build up. Since I have replaced this part my freezer has been at 10f and no more ice. It works perfect.
