My wife put the faceplate on the oven control while I accessed the display by pulling the oven out, unplugged it, and removed the rear cover. Only three nut head screws held the upper back panel. 4 nut screws hold the display onto the oven, they were easily removed. My wife took a couple photos of the rear wiring to ensure we plugged the new oven control in properly (there are a fair number of wires but they are color coded in most cases). Turns out we didn't need the photo. As we pulled a wire from the old control we immediately attached it to the new display (since there were two of us). A bit of tugging was needed on a couple of wires to get them off the old display. Once the new display was wired, I remounted the control to the oven and reattached the rear cover. I plugged the oven back in and tested all the functions on the display. Once I verified the oven control was working the burners, oven, etc my wife and I pushed the oven back into position.
I highly recommend you purchase the faceplate that goes with the control. As a test, I tried to peel the old faceplate off - forget about it. You'll save a lot of time if you get a new face plate.
