How to Troubleshoot & Replace Whirlpool AP4360756 / 7920P230-60 Cooktop

I pulled the cooktop from the counter and (carefully) removed the broken glass top from the pan. This proved to be harder than expected, as the 20 screws holding the glass to the pan had been over-torqued. I had to use my driver drill to get them off, and even then one was stripped. I finally did get it off by repeatedly bending the glass/frame until the screw was loose. Then, when I took the new cooktop out of the box I noticed that it had a ding in the front edge. Since it's symmetric, I loosened the power cable (I had flipped the breaker before I started the repair) and turned it around (rotated the pan 180 degrees). I was careful not to overtighten the screws when attaching the new cooktop to the pan. Then I powered up and checked everything out. Voila! The burner control knobs are now on the left, but it looks great!
