The new one arrived in a couple days, and for me was simple to install, although a little finicky and some trial & error but it does fit exactly and works great.
•A #2 Phillips screwdriver and some electrical tape is all you need. A magnetic probe is nice to have if you drop one of the mounting screws inside the ice tray (don't ask me how I know). It took me just under two hours from moving the fridge out to moving it back in place.
•Look over the new ice maker and notice that you don't have to remove all of the screws on the old ice maker or the door panel.
•Unplug the refrigerator and turn off the water supply to it.
•The best way is to remove the smaller inside door panel containing the ice dispenser motor, with the old ice maker still attached (hereinafter just "panel").
•install the new ice maker, being very careful to keep all the wires & harnesses tucked out of the way so that the back is flush against the panel. Be sure the bottom of the ice maker frame is above (resting on) the lip on the panel. The screw holes must line up properly. •Fasten the ice maker to the panel and check that the ice bucket fits and removes easily. If not, the ice maker may not be up fully on the panel lip or not totally flush against the panel.
•Tip the panel so that the ice maker is up under the water spigot and be sure it is all the way up and back, and finally that the panel & ice maker is back in the door all the way so that the ice maker door latches properly, and the panel mounting screw holes line up, fasten panel screws.
•Be sure the ice maker switch is on, replace the ice bucket. Turn the water back on and plug the refrigerator in. The refrigerator won't start immediately- this is normal. Your settings should have remained. Whew!
My new ice maker is much quieter and makes ice quickly after initial startup. The ice maker has to get back down to freezing, so it may take several hours to make the first batch. After that, it is more rapid. I threw out the first bucket of ice, just as a precaution to "flush " the system before using any ice.
