Product review (5 stars): Perfect Replacement for Whirlpool Icemaker
The icemaker in my Whirlpool refrigerator (Model# ED5RHEXNL03) of 7 years was making a ticking noise.  Upon further inspection, the white gear wasn't moving as it should.  The broken gear was making a loud noise as it tried to eject the ice, but couldn't.  I ordered the part from Amazon and when it arrived, my husband set about replacing it.  He ran into only one snag.  There was still ice in the tray and it made the 'D' shaped pin immobile.  After getting the ice out, it was a snap.  It took ten minutes.  In about an hour, we heard newly made ice tumbling into the bin.
The part fit perfectly, it was brand new (as described) and very easy to replace.  What more could you ask for?  I'm loving it.
