This top burner knob is a little over two inches in diameter. It has a chrome strip of trim around the perimeter of the knob, as well as white lettering denoting the off, light, and high positions.
The top seal was too long (my fault, ordered wrong length seal) so I had to cut it and high-temp epoxy the metal hook into the end. Overall pretty easy fix.
I removed the 2 screws that held the housing on at the back of the stove. Then I removed the 2 screws that held the module to the back of the stove. Since I am not an experienced electrical person (I am a female nurse in the operating room), I unplugged 1 wire at a time from the old module and plugged it into the new module. I repeated this step with each wire to make sure I didn't put the wrong wire on a wrong spot until I had all the wires to the new module. Then reattached the screws, plugged in the oven and presto, it works just fine! Was amazed at how easy it was. A 50 dollar part instead of a new 1500 dollar stove. How easy is that?
