Product review (4 stars): works good so far
Had some trouble getting a driver short enough to fit inside my smallish freezer. Once I figured that out removal was easy enough. New unit went in fine. I used my freezer's existing wiring harness.  I also used the new metal shutoff arm with no problems.  (Dont forget to install arm before installing, as I did.  I still was able to install it but was more clumsy.)  My fridge is a Kenmore Coldspot side-by-side unit. The bit of trouble I had was cutting out the perforated section to allow the water fill shoot in. I used wire snips to peck away at it but it would send cracks through the whole area. I was afraid the unit might leak but so far it seems OK. Maybe a solder iron might work instead to melt it away. I now have more ice than I can use.
