Product review (5 stars): PERFECT replacement for Whirlpool "IceMagic Plus" - important details below
First, this video is your friend: [...]

Watch it before you follow my directions below, and watch it all the way through before starting. That was all I needed to do the removal and install, though here are a couple points which apply to replacing IceMagic Plus units.

IceMagic Plus is just a fan, a switch, some wiring, and some plastic, which connects as a module in place of the normal white cover on the front of the icemaker. Do yourself a favor and use a long large flatblade screwdriver to release the two black metal clips which hold the IceMagic Plus module to the rest of the icemaker *before* you remove the old icemaker from your freezer, but after unplugging power and turning off water, of course. You have to get this module off in order to remove the plug on the wiring harness from the icemaker during removal, and you may find the other end of the harness is permanently attached to inside of freezer, unlike what you see in the above video. You'll also need to remove these clips from the old unit after it is out (pivot to one side then use needlenose pliers to pull clips out) and reinstall these clips before installing the new icemaker *without* front cover installed. Once it is in place, with the clips installed, just push the whole IceMagic Plus unit onto the front of the icemaker module you installed (without the front cover) and you should be good to go. Of course you can leave the IceMagic Plus module off and just use the cover, but why give up the bonus functionality which makes ice faster when you might need it later?

Unit can take up to several hours before it does anything while it waits for thermostat to detect the whole unit is cold enough. I didn't have to level my unit (it uses the stock slide-on mounts and not the ones in the plastic bag) or adjust water level. I did move the white plastic mounting bracket from the bottom of my failed original icemaker instead of using the one provided with the new unit. Also, it is a little tricky to cut out the rear water opening with a razor knife, but can be done if you are patient and BE VERY CAREFUL. If anyone has a better way to remove it, please add a comment to my review.

If this was helpful to you, please click that it was useful to help it be higher in review listings, so others can save big money on this fairly easy DIY repair. I am sure the labor would have been more than $75 to have someone come out, and even then they'd probably insist on selling me a much more expensive unit as well!
