Product review (5 stars): Really Easy to Install
It took me only about 15 minutes to install and it worked perfectly.  It took a couple of hours for the unit to cool down and start making ice.  I paid $44 for this unit with expedited shipping.  This compares to over $200 if I had called a service technician.  I could not believe how easy it was to replace the ice maker.  The biggest help was watching a video I found on YouTube ([...]  You may still need to take some parts from the old ice maker to have it fit properly in your refrigerator.  Make the new unit look just like the old one before you install it.  Even if you mess up you can always call for service.  You'd only be out about 40 bucks.  It'll be worth the effort and took little skill.  Get over your fear and go for it.
