Product review (5 stars): This Is The One To Buy, Don't Buy A Cheap Generic One
This is a great product.  It sure beats the original one. My fridge is an older GE side by side. It had three screws holding the original to the left wall of the compartment and the water entered from the back. The male electrical connector in the unit required me to use the complete length of the cord.
  I read some people struggled with this..."the cords too long and hangs down".  Well I just test-fitted it first (test fit:  just drop it over the two retaining screws manipulated the cord the way you want it: not hanging and with the cord connector in correct alignment with the one in the wall of the unit, then remove the unit). Make sure the switch on the new unit is OFF when doing this.  You'll find out whay later.
  After doing this I heated the cord with a heat gun on LOW, this softened the sheating up and allowed me to squash cord into kind of a long-flat-s shape.  Then let it cool in that shape,  You get the idea.
  As I said, my water source it from the rear and there was no water cup/trough on the old icemaker, water just came out of the tube into the ice tray.  Well ,in this kit there is a water cup/though that just snaps into the rear of the new ice maker (THIS IS NOT MENTIONED IN THE INSTRUCTION BOOK).  That's cool, but wait the tube in the back of the ice compartment is TOO SHORT!
  DON'T try to pull the old one out of the unit.  The one in the kit is designed to slip right over the existing one. No clamps needed.  So, if your original one is too short, cut the new one to the correct length and just slide it over the original tube. Don't worry about being too precise with the length you can slide it back and forth with little effort if it doen't fit quite right into the cup/trough. This is another test-fit that should be done before the next step. Once you have the right location leave it in that position.
  Almost there.  Make sure the switch is in the OFF position on the new unit.  If not OFF chances are the water solenoid is going to energize when you plug in the electrical connector and dispense water into the freezer compartment.
  Now you are ready to just slip the new unit over the two screws while slipping water hose into the cup/trough, plug in the electrical connector and then tighten the two screws.
  Put the ice catcher and whatever else you removed to gain acces to the ice maker back in position.
  Turn the switch to ON. The water solenoid should have turned on and filled the tray as soon as you put it in the ON position.
Don't worry if it did not.  If you are sure that the connector is properly seated and the water source to the ice maker is okay. Just close the door and walk away. The tray has to get to the right temperature before it can start dispensing cubes.
  Within 24 hours you will have 400 ice cubes.
