Product review (5 stars): the screws are very delicate and strip easily. " Sure enough the very last screw stripped ...
Our new to us house came with a Kitchenaid YKERA807PS00 range but half the buttons didn't work - most importantly the self clean button  My DH installed it in about an hour using these instructions we found on the internet:" My Repair & Advice
Unplugged the stove. I had to remove mounting screws from under front panel. Then Remove the side panels in order to remove the trim. Under the trim there are two gold screws that hold the front panel in place. Unplug the membrane switch and remove the 4 screws that hold it in place. mount the new membrane switch and use plug it in. Then replaced all screws. Plugged stove back in. It took me about 45 minutes to find the final screws hidden under the trim under the side panel. Also make sure to have the different size screwdrivers, the screws are very delicate and strip easily."  Sure enough the very last screw stripped and we needed to make a trip to our local hardware store to buy a "screw unstripper"  Thankfully they had a tiny one in stock and it even worked!  These stoves cost over a thousand dollars new and they made them with such cheap soft screws!  Now Shameful really. All the buttons work now and I'm eager to try out the self clean.
