Malcolm for Model Number NGP745UC/01 I have a Bosch Natural Gas 4 burner cooktop (NGP745UC/01) that I recently installed. Three of the 4 burners light with no problem, however the 4th burner, the lower right (with simmer) that would be used the most, has good spark but will not light. Additionally, that same lower right burner sparks when any of the other three burners are turned on. From reading other posts it would appear the spark switch for that lower right burner needs to be replaced, however the sparking on that burner when not turned on doesn't seem to fit any of the other diagnosis. Thank you
Answer Malcolm, Based on the information provided I would start by checking to see if the burner lights with a match or lighter. If it does then check the burner holes near the ignitor to make sure nothing is plugged or stopped up. If that is not it then check the gas and air adjustments.If it does not light with a match or lighter then check the gas valve for that burner. Read More...
