The left front burner would not turn off, and the switch was sparking

First I unplugged the stove, and removed the upper-back panel. Then I pulled off the control knob. Then I removed the two screws holding the switch to the stove. Then one-by-one I removed the wires from the old switch and connected them to the corresponding tabs on the new switch. Then, using the knob adapter supplied with the new switch, I figured out how much of the knob shaft I had to remove from the new switch to position the knob the correct distance from the face of the stove. Then I tested the switch with a voltmeter as instructed, and then I hooked up the last wire.
Partselect.com is an awsome website!!! I was able to review comments form other do-it-yourselfers that had similar problems. Then I looked up the Partselect schematic drawings of my stove and was easily able to find and order the part I needed. The part arrived at my house within a couple of days and I had the stove fixed in no time.
