JGD8430ADB Jenn-Air Cooktop - Instructions

I took the old knob off, got needle nose pliers to get the small steel sleeve off the post, and put the new knob on. The knob had a number on the underside, but it is not the part number. Part Select's picture showed the number, so I knew it was the right part.

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

removed the two screws holding the burner to the cooktop, disconnected the wire clip from the electrode then removed worn out electrode from burner. Re-attached the new electrode to the burner, re-attached the igniter wire then put the burner assembly back onto the cooktop

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!!

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

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!!

remove grate - flip upside down - be sure holes are clean and dry - using toothpick, swab some RTV sealant into the holes and a bit on the pads ... insert pads till they seat - be sure to hold in place till all air is evacuated - wipe excess RTV with paper towel...DONE

just replaced with a new one. very easy

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

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

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.

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.

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

Installation is simple and very straight forward. Problem, was i stripped the torx screw to release electrode because the screw was frozen. I then tore electrode out leaving space to use penetrating oil (inaffective ) then using a chisel to pop the screw out. It came out intact and did not damage the threads in the burner. So what could have been a 20 minutes job, turned into over an hour. But still worth doing myself.
