Product review (5 stars): Saved over $230 doing it myself
Works perfectly...no more ice buildup.  Took about 30 minutes from start to finish taking my time (after viewing the appliancepartspro video on replacing this part).  I had originally contacted a repair service and the tech quoted 2 hours and $249.99 for parts and labor...ain't gonna happen for something this easy (and cheap) to repair.

The original duckbill valve was GROSS!  Showed it to my spouse and she gagged.  Shame on Whirlpool...who made my Maytag...for not stepping up and sending all owners of this model a replacement drain line gratis.
