Part worked like a charm. Wiring diagram supplied clearly mapped out where to make the connection from old to new. Not only did it fix the burner not turning on, it also dramatically reduced the burner's response time to heat up. Such a difference I ordered 4 more to replace the originals that are still working. 30 years of technology improvements to a simple switch does make a difference. The accompanying sleeves for the shaft to fit the knob worked. The only suggestion would be to have longer mounting screws on hand. Those supplied and the originals were too short. I rummaged through my jar of saved electrical receptacle & fixture screws for 2 that did the job.
