When one burner is in operation, we will get sparking at another burner even though it is turned off. No gas flows so there is no light-off. Sparking is intermittent and happens mainly to the two center burners. When one of the center burners is on it will also spark.
Answer Hello Jeff,
When one ignitor sparks, all of the ignitors spark. When the ignitors spark it is an indication that the spark module isn't sensing the flame at the burner that is lit. This means that you either have an ignitor failing, a poor ground, or the spark module is going into failure.
