This problem was driving me crazy for months. Of course, after I bought and installed the part and it still was not fixed I finally found a website that told me how to fix the clicking. The problem is that the removable head burners (#8 on the top assembly diagram) are not making good electrical contact with the base burners (#22). What I ... Read more did was grab the head burners and grind them back and forth into the base burners with the weight on the heal of my hand. Steel wool or sandpaper would work too--you just want to clean the surfaces to restore electrical contact.
If you still want to know how to replace the spark module start by removing #24. This will allow the removal of #9 (after you take the knobs off). You may have to do some fiddling cause the rubber gasket is sticky. Next there are 2 obvious regular screws for #14 and 2 not so obvious star screws in the space where the burner valves are. After #14 is off there are 2 screws on the spark module to be removed and one that you can't loosen that is in a slot. You wriggle the module out of that one.

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 h ... Read more ad 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.
