Replace the buttons on a kitchenaid microwave Khhs179lss-5

First, you need to uninstall the microwave (MW) from the cabinet by removing the screws that hold it in place at the top. Open the cabinet doors above the MW to locate the screws.
You will need someone to help you at this point in removing the screws and dropping the MW down. Be sure and unplug the MW before you remove the screws.
Next, you need to take the cover/shell off by locating and removing screws A/R. They are mostly across the back and side bottom.
From there on out, you should be able to methodically find and locate the various fasteners that will get to the button pad.
