Product review (5 stars): but you can just to be super safe. The wires from the freezer wall to ...
There's more than one installation video to be found on the YT site, but even if you've never replaced one of these it should only take several minutes, so don't worry. You don't have to unplug the fridge, but you can just to be super safe. The wires from the freezer wall to this unit are a little stiff and I highly recommend removing the wire shelf that sits underneath this unit for ease of removal and installation, but other than that this is a breeze. And, as many others have stated, I had ice dropping within 2 hours of installation. This sure beats calling out a service person and getting charged probably $200+ for something most people can do themselves.

One last note - this is the 2nd time I've replaced my icemaker - the first replacement unit I bought from a discount online store, and while the price was a good $20 lower than what I paid for here on Amazon, the build quality was substantially lower -- the tray looks better and has a better coating, the "fingers" on the rotating arm are bigger and stronger and have a texture, and even the gears underneath the white square cap on the end look as though they are a higher quality metal.

Thank you Amazon for fast shipping and automatic ice!
