Product review (5 stars): Great replacement ice maker for my Maytag
This is the standard replacement for several major brands of refrigerators.  Don't let the picture fool or worry you.  The picture is reversed/upsided down mirror image of how the unit goes in your freezer.  To take your old unit out, there are two sbrews on the top above the ice cube tray & optional on most one screw below with a small plastic wedge. Take them out, unplug the power cord and it comes right out.

The new ice maker comes with a short (about 5 inch) wiring harness which you can see one end of it in the picture.  My Maytag did NOT need this part becasue my wires come right out of the freezer wall and are long enough to strech to the front on the unit where they plug in.  On some brands the wires do not come out of the wall but have a plug in the wall.  For these they are suppling a new cord.

You will need two things from your old ice maker.  There is a platic cover that pops on/off the front of the ice maker that covers the moter/grears.  The other is the thin metal rod that goes from the front to the back of the ice cube tray.  It it the one you push all the way up to stop the maker from making ice.  To remove, the back just pops out, the front has to be twisted out.  Just go slow and don't force it, one way will give the other way won't.  Repeat to install the metal rod on the new ice maker.

Just plug it and screw it in & your good to go.  It make take some time for the first batch of ice to fall.  I suggest letting several batches fall and pitching them in case of any residual stuff left on the maker from production.

Sears and other appliance stores and sites charge upward of $100 for this.  At less than $50 this is a great deal.  I scrolled down and used the "Buy Used and Save" and got a returned unit for $31!
