Question about KitchenAid KHHS179LSS Convection / Microwave Oven
Your membrane keypad has probably failed.
If it is still under warranty, please contact the manufacturer's number in your owner's manual.
If you might want to replace it yourself, I have uploaded a handy guide with pictures showing you what's typically involved.

Essentially you unplug the oven from the wall outlet, and remove the control panel assembly as per the instructions at the site linked above.
(Remove the grille from across the top, remove the top screw in the control panel frame, then lift up & out).
There should also be a very helpful "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille.
Then unplug the keypad from the circuit board, heat up the keypad from the front with a hair dryer, then peel the old keypad off.
You have to make sure all the old adhesive is off or the new keypad will not stick.
I use paint thinner or mineral spirits, then follow up with isopropyl alcohol to be sure the panel face is squeaky clean and dry.
Then peel the backing paper from the new keypad and carefully press the new keypad in place.
You need to be precise - you cannot apply it, peel it off, then reapply it.
If you would like to have us do this for you, we do that for $39.95 plus part costs.
