If you have a burner that begins to constantly flick without lighting, and/or flicks while you are lighting another burner, it is likely time to order a new ignitor. Once received, we first lifted the burner support rack, then the burner cap, then unscrewed the nut holding the metal bracket that holds the ignitor in place (years ago we had to "soak" the nut with a loosening spray prior to being able to unscrew it, so since then we do not tighten the nuts too tightly so that each nut is easy to unscrew by hand or with pliers if necessary). The previous steps allow one to lift the burner ignitor up and out of its resting hole. It will be connected to the electric wiring via a plastic connector. All one has to do is pull the wiring away from the ignitor and then push it up into the new ignitor. The plastic connector protects you from touching the live ends of the wiring. Voila! The burner lighted successfully.
