Burners kept clicking after ignited
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 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.

stove top gas burner ignitor only flicks but does not light burner
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.

the spark igniters would continue to spark after the burners were lit
Since the problem would only occur when the right front burner was on, I first replaced the ignitor, but the problem persisted. To replace the spark module I had to pull the range out of the nook it is in in the counter top. Then (after ensuring that the power was off) I removed the back cover. The spark module was easily located and removing two screws and disconnecting a few wires liberated it. The new one went in easily since it is the same part number and an exact match. Put the back on and check that the problem was solved. Done!

One burner would continually keep sparking after burner ignited
Removed the small access cover on the bottom of the cooktop by reaching inside and under the cabinets. Removed the module which was held by two hex head screws, unplugged the wires noting the location and color of the wires. Plugged the wires into the new module in the proper locations as noted previously. Attached the module with two screws, and then attached the cover/access plate with two screws. Problem resolved, repair was easy.

Ignitors wouldn’t stop clicking when using front right burner
Installed new spark module by removing back panel of stove. Removed two screws holding old module. Disconnect lines, marking colors. Installed new. Problem not solved. Out $128 since new module was not returnable after install.
Called Judd and Black service department. Tech came on service call. Said it was bad gas valve. They ordered part. Than needed two weeks to install. I installed it and problem persisted. Could not return part because I installed it myself. Out $180. I had cleaned ignitor with alcohol from top. Took apart cooktop and cleaned from bottom. Problem fixed for free. Out over $500 in parts and labor.

Conversion back to natural gas From propane
I converted the cooktop from propane to natural gas, the parts I was told I needed were the incorrect parts. I called because I was not sure about the listed parts. I was helped over the phone but recieved the LP parts. The flame was very low, and i found the orifices I replaced were the same parts I just took out.I contacted Parts select and they were helpful and credited my purchase without any hestitation.Once the new orfices were recieved it was easy to install. I recommend using a nut driver with sticky tape to go the orifice holder after the venture is removed. You do not have to disassembe the stove as long as you don't drop the part. Changing the regulalor was also very easy by removing the gold nut and pulling the white pin out and flipping it over to Nat. The flat side of the pin is labeled LP or NAT. Then just screw the nut back in and tighten. The LP orifices are labeled on the side 0.65, 0.69, and 0.70 the natural gas orifces are colored black, silver , and red. It would be just as easy to go from Natural gas to LP!
