I ordered the part from AppliancePartsPros.com which arrived promptly - I watched several videos (not all of them had all the information so watching several gave me more information than any single one did) -- I took apart the panel as directed and bought a heat gun to help with removing the old sensor pad though one video showed a guy removing it without the heat gun - the heat gun really helped though so I'm glad I saw that video first. I then peeled the backing off and applied the new part -- I'm not great at lining up those sticky things (like with my cell phone protector) but it fits pretty snugly into the panel edges so that made it easier -- I was just the tiniest bit off on the left side but rather than possibly ruin it by ripping it off to try again, I put it all back together (getting those screws back in place must be really hard for guys with big fingers cause I have tiny fingers I had problems), I screwed the panel in place after hooking all the wires back up, (I had to go back and look at another video to find where the white and blue odd shaped plugs went because I couldn't remember (I took it apart before I got the part so there was a waiting period between taking apart and reassembly) -- before closing it all up I plugged it in and tested it -- it WORKED!!!! So I finished putting it all together and now I have a fully functional beautiful built-in microwave --- I had just bought the house and didn't know the microwave didn't work so I was totally delighted that I didn't have to buy a new one. I did it MYSELF!!!
