One burner ignitor won't spark. If it does spark it will only make one spark.
Answer Hi Don. You will need to replace the igniter after using a brass wire brush and clean the burner cap where the spark path normally occurs. If there is not a fresh ground area then spark will not occur. But it is very common for the igniter body to weaken and crack then the spark will start to travel to the nearest chassis ground and not the correct path. Igniter part # WB13T10077. Thank You.
