Ice Maker stopped working-Fridge failed to defrost and stopped cooling in both compartments.

I popped out the side panel to the right of the ice maker and removed the ice tray-then used a nutdrive to remove the screw under the ice maker. Lifted up on the unit , dropped it down and used a flat head screwdriver to press the tab in on the electrical connector at the rear-then removed the unit from the Freezer. The end cap that covers the controls on the old unit snapped off easily as did the small metal tab (both needed to be placed on the new one) and I re-installed the new ice maker doing the reverse of the removal. Watch to make sure that the white rubber water line goes back into place as you remount the ice maker in the Freezer.

As for the thermostat, I loosened the temperature control cover in the top of the refrigerator by pulling down on it, needed to pull out a bit to clear the control levers-easier if they're centered on the 5. I removed the retaining screw in the center of the rear of the cover using a nutdriver, and that lowered the cover enough to remove the screws that held the thermostat assembly in the upper right (also using the same nutdriver that worked on everything else). I removed the electrical connector from the old thermostat and attached it to the new one. The old thermostat didn't have a cover on it like the new one, and it was easier to make sure that the electrical connector was attached by popping the cover apart-attaching the connector, and then snapping it back together. The new unit snapped into place by pressing down firmly, then I re-assembled the cover plate doing the reverse of the removal.

If you don't count the two hours that I spent defrosting the freezer coils with a hair dryer-these were FAST repairs, and the refrigerator is running like new again
