JGD8430ADS Jenn-Air Cooktop - Instructions

Firts I removed the 2 screws that held the burber in place. Then I lifted the burner up & disconnected the wire that connected to the ignitor. Then I removed the one screw that held the ignitor to the burner. I then reversed these steps, replacing the cracked ignitor with the new one, replaced the screw holding it to the burner, then reconnected wire, returned the burner to the stove and replaced the two screws that held it. All Done!

- Removed the cover.
- Removed te two Torx screws.
- Pulled the burner a couple of inches to be able to disconnect the wire.
- Spent a lot of time removing the small Philips screw holding the ignitor. Ended up breaking the ignitor with pliers to be able to put WD40 under the screw's head.
- Treated all screws with a high temperature copper paste to prevent oxidation.
Installed the new ignitor with the new screw.
- Reconnected the wire.
- Installed the two Torx screws.
- Voila, it works.

Removed grate and burner cover (held on by gravity - no tools needed) then removed the two screws holding down the burner itself. These screws are Torx screws so you will need a Torx bit set (looks like a phillips head screw driver but is star shaped). Once these screws are out, the burner lifts off to reveal two phillips head screws holding the ignitor in place. Remove these two screws, un-plug the ignitor, plug in the new ignitor and replace the two screws holding the ignitor in place. Be sure to have the ignitor centered. The first time I put the new ignitor in place, it was touching the frame of the stove, so it failed to spark since it was grounded. Replace the burner and two torx screws and replace the burner cover and grate. Done and done.

I removed the burner cap and then the two screws that held the burner in place, pulled it out about 3 inches, disconected the ignitor and pluged the new one in, put the burner back in place and put the two screws back in, replaced the burner cap and it was done. I would also like to mention that I ordered my replacement part on Sunday evening and recieved it on Tuesday morning. Thanks Part Select!!!

I just put the grate pads in the bottom of the grate. The repair was a snap.

The igniiter is made of ceramic and had cracked.
I remove the burner assembly, but couldn't remove the screw holding the igniter. After trying liquid wrench and every available screw driver. I opted to order the complete burner assembly. I installed the new assembly in 5 minutes and it worked great. This is the second ceramic igniter that has cracked on this stove top and both times I've had to replace the whole assembly. For a $1000 stovetop, I expected better quality. I'm just wondering how many times I'm going to have to replace burner assemblies. Each time it's been a different assembly.

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.

Original bumper pads NOT glued into the burner grates. Hence they began to disappear during routine use and cleaning. Very simple repair with a little glue this time around. But fairly expensive for a very small part set

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.

Been looking for grate pads for 10 years and finally found you site and part # WPL 814323.
Wasn't sure that they would fit but couldn't even find new grates so decide to try them --Fit perfect.
Kitchen aide stove top gas with round grates. Used the drill to clean out the holes with broken pads still embedded.With clean holes the new pads just screwed in like the originals. Thank you very much

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,

Ordered new knobs & now all burners work. Easy installation.

cleaned out pad area with an awl. then the pads just slide in.

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 .
