Michael Keaton for Model Number RDFS30RS I have a Thermador RDFS30RS. One of the simmer burners does not light. When I turn the burner on, all other burners spark but this one. I can light this burner with a match, so it is getting gas. All other burners work as expected.

If it still does not light then the spark module itself would need to be replaced. It would depend upon if it has a potentiometer or a spark switch. 00753257 is the spark module 00497235 is the potentiometer and is not available 00189008 is the spark switch Read More...
