Product review (4 stars): Great replacement part. Best price I found for this unit. Some vendors wanted double the price for the same thing.
Worked as expected. After viewing online videos I was able to replace the defective one with this service unit. Except for cleaning the inside of the door and watching for sharp edges, this swap was easy-peasy.  Took 45 minutes, partly because I was particular about cleaning inside the door and the surounding area after removing the old defecting unit.
