Product review (4 stars): Close to older (discontinued) kit I needed
Glad I found something to repair my Thermador cooktop slow simmer burner.  I had a bad potentiometer for a not-that-old model and you can't get them anymore (discontinued item, infuriating!) so this was not an "exact" kit for what I needed.  Only problem was that these potentiometers did not engage (mount onto) the gas valve bodies properly.  I was able to remove the pots from the mounting bases and re-install on the existing (older) bases so they would mount OK on the valves.  So now, we're cookin' again on all burners.
