Product review (5 stars): Defrost works once again
Our freezer's defrost was having "issues". Food got way too freezer burned.  And the defrost cycle got way too warm - food got soft, ice cubes in the bin melted into one big glacier, etc. Good videos online show how quick of a repair this is. It makes it so that the defrost ends when it gets to the right temperature, as opposed to going the max duration set forth by the defrost timer.  GE GSH22JFTABB, ~2005 DOM. Worked like a champ. Ice no longer clumps, and food rarely freezer burned.
