Product review (5 stars): I'm so proud of myself!!!!
An appliance repair man wanted $150 to replace our broken icemaker.  It worked when it felt like it, and water leaked from both ends when it did.  On a whim, I ordered this piece.  Make sure you put your ENTIRE model number.  We have a Whirlpool, and the model number on the door was different from the model number listed on the right side wall of the fridge.  The assembly comes with several different wiring arrangements.  What I did was leave the original wiring, unplug the wire that came with the assembly and plug the old wiring into the new assembly.  I did this because I knew the old unit was producing ice, so there was no electrical reason why the old wiring wouldn't work.  If that ever became the case, I still have the wires that came with the assembly and can switch them out if necessary.

All you need is a ratchet that fits the existing screws on the old unit.  Truthfully, if you don't know what you're doing (like me) I watched a few YouTube videos on how the install the unit.  It's really simple.  UPPLUG THE FRIDGE!!!!  If you can't get back there, flip the circuit breaker.  Unscrew the bottom screw (watch out you don't drop it... it's hard to find In a freezer full of food (did you think I dropped it????  You're right if you did).  There are two screws on top... just loosen them and the unit can be lifted off those screws.  You'll see on the bottom a a little square with a lever that you can push with a screw driver and that will release the wire plug that goes to the wall of the freezer.  Remove the old unit, plug the plug into the new unit, set it in place over the 2 top screw, insert the bottom screw and you're good to go.

Here's where I freaked out... It didn't make ice for two days, but I read that the unit has to reach a certain temperature to produce ice, so I let it go another day, and then back to YouTube... Why is my new icemaker not making ice? So here's where the Freak started...  I needed to "jumpstart" the motor.  You take a wire with two bare ends (make sure it's insulated... wrap some black tape around it, or a piece of rubber, and insert the ends into these tiny holes marked T and H on the front of the unit.  I cut an old plug from a radio that didn't work, scraped the plastic of the two end twisted them.  I wasn't sure if I was going to set the house on fire or electrocute myself, but neither happened... The dial started to turn and I heard water fill the tray.  YAY!!!!!  It's working fine now, and I have a full ice bin.  Took about 2 days, but I'm so happy not to have to buy bags of ice anymore... been doing that for a year.

This is a great way to go to save a bundle of money.  Delivery was quick, and everything you need came in the box.  It was in perfect condition, and this is a genuine Whirlpool part, so there's no problem with fitting.  You will find tons of help on line via YouTube and many handyman websites.  Watch out for sites that want money to tell you how to fix something.  I'm sure they're helpful, but there are many, many free sites.

Good luck!!!
