Product review (5 stars): Whirlpool 2198597 OEM Icemaker
The icemaker arrived damage free in excellent packaging.  I had reviewed online videos prior to arrival so, I was fully prepared for the installation.  Every step of removal and replacement went exactly as demonstrated in the video I referenced.  I had the new icemeaker swapped out in less than 30 minutes.  I could have done it faster but I took time to clean all parts prior to installing.  After I turned on the new icemaker, it took two hours for the freezer temperature to return to the operational range (5 degrees to 10 degrees above zero).  The first batch of ice dumped and cycling between batches ran 45 minutes and the bin was full in under 12 hours from empty.  It has been installed now for 3.5 weeks and has not skipped a beat.  This install and trouble free replacement is due to purchasing the original equipment part; quality is same as the icemaker that came with the refrigerator.  Cheaper units were available but for my money I want OEM parts...I expect this will last the same five years as we got from the original

I highly recommend this OEM icemaker for ease of installation and expectation of longevity.  And, take the time to view online videos prior to tackling the swap.  Be patient, observe the disassembly carefully and it will go back together properly and you will be amazed how easy it is to do it RIGHT and save some serious cash.
