Product review (5 stars): Works well!
I bought this for a Kenmore 7909611340.  I have had issues with the left-front burner.  Occasionally the burner would not shutoff when the dial was tuurned off and one time, came on by itself!  It also had issues at low settings and would only really heat up at high settings.  Finally, while cooking, I heard a small pop and smoke from the back of the range.  At this point, I knew the switch was done.

I went to Sears Parts online to find the part and the nearest store.  I found the part number (which happened to replace the OEM part) but the nearest store was closed.  I decided to give Amazon a try.  With Prime I got it sooner than I would have if I had waited for the next opportunity to drive 20 miles to the nearest Sears Parts store.

The part was relatively easy to install.  One thing the instruction tells you do when breaking off the stem to fit your dial is to use pairs of pliers to break the stem and not use the body of the switch.  It is noisier then the original switch when it activates but I'm just glad it works.  Will see how long it lasts.. but so far I'm happy with the results.
