JGD8430ADB Jenn-Air Cooktop - Instructions

Installed new igniter, but would still not light flame. Determined it was a design flaw. On our range, the 2 right hand burners have "lift-off tops" that are farther away vertically from the igniter than the smaller left hand burners. I placed asmall nut from a nut-bolt assembly on top of the igniter, and now the igniter sparks higher to the "lift-off top" and the flame ignites everytime. Without that added heigt, the igniter just sparks uselessly around the base of the burner. There should be a higher igniter designed for the higher distance between the igniter and that removable top. Good luck with your own modification.

Pulled off the old knobs, pushed the new ones on. Could not have been easier!

pull out the old knob and replace with a new one.

Removed the burner & igniter as a unit. Screws holding burner down were very tight. One came out with effort, the other one the head broke off. Tried heat but to no avail. The screw holding the igniter had to be drilled out. Fortunatly I work in a machine shop so I was able to remove the screw, but the hole was then too large for the replacement screw. I wound aluminum foil around a toothpick to form a bushing in the hole so the screw could grab. Same principle as those plastic anchors for plaster or drywall. Bought stainless screws, but did not even try to get the broken screw out of the cooktop. The one screw holds it in place just fine. Wife is very happy.

Bought The burner with the electrode already installed. The only way to go, since the screws will not come out without breaking. Also purchased two torx screws as thay also broke. A bad design by the manafactor.Had to drill and tap out for new torx screws to fit into the gas houseing. PartSelect had all the parts I needed. Dan

Screws holding burner base and ignitor were plain steel. If they had been stainless they probably would not have rusted in so tight. One in the base broke off, and the one holding the ignitor could not be removed, even with heat from a torch. I ended drilling it out and re-tapping the hole. If I wasn't mechanically inclined I would have had to give up and order a new burner base.

I lifted the burner tray from stove turned it upside down then removed six small screws from side of cover pan then I removed the cover then I removed the screws from the back of the old burners and igniter.Then I turned the old burner counter clockwise and it lifted out easly. the igniter is removed with no problem. The new burner is put in place and turned clockwise to lock in place.Then replace then the gas tubes and igniter and igniter wire then put tray cover on.

A crack in the porcelain caused the spark to not go in the proper direction, therefore the burner would not ignite. To have the job done by a professional would have cost $200.00 plus parts. Remove two phillips screws lift the burner out then remove the one phillips screw that held the electrode. Then with the new electrode in place reverse the previous steps.

I took a jewelers screwdriver and completely cleaned out what was left of the old pads. Then applied a small amount of heat resistant rtv sealant to each hole, slid in the new pads and wiped off the excess. I let everything set overnight. The next day everything was solid. Job was complete. Note I've done this before and did not get the results I did this time. I believe it was the instruction that came with the pads and the tip-off to use the rtv. Thank you PartSelect T.Garr

I just took-off the old one and put the new one by hand.

Simply unscrewed the old one and installed the new one and we have ignition!

The original knobs were poorly made and kept braking. After the third set, which were very expensive for some plastic knobs, I read this web page for help. Based on what I learned and what I read, I glued the metal sleeve in the knob shaft with some super glue. I then wrapped the shaft with copper wire and spread some industrial glue over the copper wrapping, which looked like a spring around the shaft. I have had no problems in the last month. I hope it keeps up.

After determining it would not be possible to replace the electrode only (rusted/corroded connection), ordered burner head with electrode. Part came in approx. 24 hours. Actual repair involved removing two screws (star-shaped head),disconnecting electrical clip, removing part, connecting electrical clip to new head, reinstalling two screws. Works great now!!
