JGC8430BDS Jenn-Air Cooktop - Instructions

I've done this once before on this same gas stovetop as the electrode can degrade if it suffers from too many "boil-overs". The most important thing to do if the 2 screws holding the burner head on the cooktop are "tight" and don't unscrew easily is to soak them with WD-40 to loosen them up. Don't be in a hurry. They may need a couple of soak and waits. Once the screws are out, it's just a matter of connecting the wire on the electrode and replacing the burner. Also a Star screwdriver that fits properly is essential.

First I removed the two screws that held the element in place. I then pulled the element out about 3 inches to disconnect the electric wire - it had a small bayonet connection. I turned the element over and unscrewed the small screw holding the ignitor to the element freeing the ignitor from the element. After receiving the part from Part Select, I reversed the process...

1. attaching the ignitor to the underside of the element using the small screw.
2. reattaching the electric wire to the ignitor.
3. positioning the element on the stove top.
4. reattaching the eelement using the 2 screws.
5. testing and finding it worked fine.

A couple of observations:

1. The screws holding the element to the stove are star screws while the screw attaching the ignitor to the element is Phillips - necessitating 2 different screwdrives for an easy repair.

2. I had problems with the initial part delivery - it went to a wrong address. PartSelect Customer Service was great. I had a less than 5min wait for getting a rep on the line with the 1 call I had to make to get this corrected. And when I did get a rep she was both helpful, friendly and knowledgeable in correcting the situation.

I thought I had ordered metal knobs but it appears that I got plastic ones. I’m thinking they’ll be fine, the others had just split the shaft that sits on the control stem, but I’m hoping this won’t happen again. I do have a repair question regarding one of the sealed burners on my Jenn-Air. The igniter switch sounds like it’s working but the burner won’t light without putting a match to it. Do you have any ideas of what could be wrong?
Thanks for your help,

Disassembly: Removed 2 screws with nutdriver. Pulled off electrode connection. Screws were rusted and needed replacement.

Assembly: Slipped on electrode attachment. Went to local hardware store and bought 5/8" 8/18 pan head screws. Used screwdriver to screw down burner head. The 3/8" inch screws on the tech sheet do not work. Too short and flange is too wide to fit in opening in burner head.

This is the 3rd burner head that was replaced . everyone had the screws break off , & had to be drilled out & re tapped .I would not purchase the replacement screws @$4.00 each . They were just plain sheet metal screws that were steel . Better going to a home center & purchasing brass or stainless machine screws at a 1/4 of the cost .If you are not familiar with drilling out broken screws ,then this is not the repair for you .

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!

It could not have been easier. All I had to do was switch out the jets in each burner. First I had to sort the new jets and match to the correct burner by referring to the owners manual. Then I removed each burner and replaced the jet one at a time. Finally I had to turn the adjustment screw on each control knob clockwise until it would not turn anymore. Plug in to an electric outlet and it was good to go.

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.

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

Real Easy!!

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

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.

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

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.

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!
