Product review (5 stars): We did it ourselves and it was easy
We were so pleased when this new ice maker showed up.  It was very easy to install.  All you do is plug it in to an existing connection on the fridge and before the day is over, you have ice cubes dropping into the tray.  Cheaper than calling a repairman, for sure.  I followed an online video for directions on how to remove bottom compartments to give you access to the icemaker.
