Product review (4 stars): Looks Like a Good fix for Whirlpool Design Failure
This product seems to be a good solution for the nuisance design flaw in our Whirlpool refrigerator which caused the defrost drain to plug with ice and overflow onto freezer floor.  I had gone through thawing the ice and clearing the drain three times before I came across this replacement for the original, faulty design.  Whirlpool should be ashamed that they would put out such a problem part on an otherwise good refrigerator.  Installation of this part was a breeze using the instructions I found on You Tube.  The only hard part of the procedure is removing the old trough that leads down to the evaporation pan.  Getting that trough separated from the evaporation pan clip was a real challenge.

The new part has only been in place for a few days.  So, it time will tell if it really works as advertised.
