Product review (5 stars): Not a difficult job to install. More time spent cross referencing old part numbers to new part numbers.
This Whirlpool Unit #W10190965 is a direct fit replacement for my 1996 Whirlpool Side by Side Refrigerator/Freezer Model #ED20TWXDN00 less 2 mounting clips, the square front cover, and the On/Off bar that detects the ice accumulator basket full.
The old part number was 106 626636.
If you buy from a local part dealer, he will quote you $100-$125 and may sell you one (a variant) with additional parts you may not need.
I used the parts mentioned above from the original unit to complete the installation.
For a demonstration on how easy it is to do this replacement yourself, search You Tube.
