JGD8430ADB14 Jenn-Air Cooktop - Instructions

Our cooktop is about 9 years old. Great appliance, but poor engineering/design choice to have aluminum knobs with plastic knob shafts, that almost every time the burner gets turned on, the plastic shaft gets stressed and they crack, rendering them useless over time. I replaced all five (5), for about $80 delivered, since I got tired of repairing them. I did see a very helpful post from a guy in Arizona (thanks if you're reading this) whose daughter glued the shafts inside and out, and then wrapped them in wire. I did the same thing with my spares (I have about 7 now, after replacing one or two over the years), as I took the metal sleeve out of the middle, glued them inside and out, and used small plastic wire ties to close them up tight, then putting the metal insert back inside. After the glue dried, I snipped off the end of the wire tie. It worked great! Thanks, Tom D., from outside Boston, MA.

It was very simple two Phillips head screws to remove the burner and one screw to remove the ignitor. It was probably less than a 5 minute job per burner. Unfortunately one burner had a very rusty screw holding the ignitor and the head stripped out. I tried a stripped screw removal tool with no success so I used a drill press to drill the screw out. It still took less than 30 minutes. Now both burners work like new

Take out 2 T15 torx screws. Lift burner assembly, disconnect igniter. Make sure wire does not return into hole. I put A paperclip on it. Connect new burner assembly. Clean under old burner. Install burner assembly with screws. Test burner.
Voila!

I actually did it manually. It was fast and easy.

Simple repair to replace stripped out knob. More importantly we ordered the part over Christmas and it arrived within 2 or 3 days

Removed the old burner knobs by hand, and replaced them with four new knobs.....

Real Easy!!

just replaced with a new one. very easy

Pulled the old one off, pushed the new one on. Super easy. Simple ordering, quick processing and delivery. Way to go PartSelect!

To be honest, it was nothing much. Had to reach and remove metal collars that were left behind around the pins, with needle-nose pliers. Put in the new knobs, and we were done.

What really left me impressed was 1) that the rep sent me pictures of the suspected knobs over email so I could identify them easily, and 2) I was expecting to wait for a week but I had the parts the next afternoon!!

The hardest part was finding the part number...and that wasn't all that bad. Perfect match; perfect fit.

Unscrewed burner assembly and removed wire. Unable to remove electrode screw. Striped head of screw. Tried penetrating oil but no luck. Tried to drill and use easy out bit but ruined burner assembly and had to order new burner assembly. When assembly came it had electrode in place but website does not show electrode with assembly except on one burner. With mail and all it took about a week to fix 2 burners. Returned unused electrode for credit. Overall, cheaper then a service call by far.

Removed the gas deflector; unscrewed the burner body; pulled off the ignition wire; unscrewed the bad electrode; screwed in the replacement electrode; reversed the steps. Voila! Perfect operation once again. My one mistake? Ordered the wrong electrode initially. Make sure you get the right part the first time around.

Replaced burner assembly.

Remove old knobs and remove old grommets. Insert new grommets, install new knobs.

parts came on time and the repair was just remove the old and replace with new.
