Product review (5 stars): Even a Pharmacist can make this repair!
Very easy to remove old ice maker and switch out.  It works wonderfully!  I had looked at You Tube videos that showed the process to keep me from being afraid to try to do this repair.  The hardest part is diagnosing the problem.  My ice tray would not release cubes, and after reviewing every trouble shooter I could find online, my gut told me it was the heating element that allows the ice to melt and the motor to turn and release the cubes.  After removing old maker and melting the ice and removing ice, I reinstalled the old ice maker but it would never fill with water.  No one at Whirlpool or online could tell me if water would not fill if it was the heating element or the fill tube that was the problem.  Anyway, I thought for $86, it was worth a try instead of paying a repairman $100 to diagnose one day, then ordering the part. and then another trip to install and labor charge to replace it less than 10 minutes.  I think I saved almost $200!
