I don't think adding extra insulation fixes any particular "problem"--it just increases efficiency. Several people have reported that it makes a pretty significant difference. I added insulation everywhere I conveniently could. Not sure how much it helped, since I never kept systematic track of running time. Certainly can't hurt.

When I had our frig on the bench trying to fix the airflow issues, I did do a test of insulation. By adding 2 layers of 1/2" urethane foil board insulation wherever I could (top sides and rear, less on bottom) we gained about 10% efficiency. I expected more, but these frigs are already pretty good, it appears.
