JGD8345ADB Jenn-Air Cooktop - Instructions

:-) - Just removed the old one and replace with the new one. Nothing to it. Takes 30 seconds.

Turn off the gas supply and unplug the electric supply. Remove the top grates and the burner cartridges. Remove 12 screws around the top cover and loosen the two screws for the fan switch. Pull the fan switch up and out of the way, remove the top cover. With a marking pen, label the four igniter switches and pull them off the gas valves. From underneath, remove the gas line from the pressure regulator, then remove the regulator from the pipe coming from the circular manifold. With a 3/16 socket (1/4 inch drive) or a 3/16 nut driver, remove the four screws that hold the manifold. Then from the top pull the manifold up and out. On the bottom, remove the screw (1/4 inch socket or nut driver) and remove the old gas valve. That's it. Now just put it all back together in reverse order. I used pipe joint compound on the pipe threads. Check for leaks with a soapy water solution. If I had to do this again, it would only take me half the time. I wasn't sure how everything came apart the first time..

This cartridge fits my JennAir Downdraft Slide In Rage, part No. JDS9865BDP. The burner cartridge replaces a downdraft cooking grill module that comes with the original stove/Oven.
The spark quit on the cartridge side. I re-inserted the original cooking grill, and it lit fine. There are two components to look at. The sparker, and the burner igniter (one per each burner). Since both failed to light, I ordered the spark controller.
PartSelect has a video on how to test for failure, but I couldn't find that again.
Two screws mount the controller, two wires re-connected. and works perfect.

The front burner had a noticible flame coming from the base, so I originally purchased a single burner to replace it (you could see a corroded hole at the bottom). Upon taking the unit apart, I noticed the corrosion was much worse than met the eye. Given the age of the unit and that some parts were already becoming discontinued I decided to gut the whole thing and replace it all.
The burner unit slides out easily and after unscrewing the sides, you have to disconnect the wires from the underside of the igniters. The venturi tubes and igniters then unscrew from the underside of the burners which twist right out of the assembly. Re-Assembly is very intuitive looking at it and it all goes right back together as it came out. Took 45 minutes total and that includes fighting with some screws that had rusted onto the burner.
Reading some of the previous reviews, current prices are double to triple what other people did the repair for leading me to believe parts won't be available for much longer. Make the repair while you still can!

Because the stove is over 10 years old the screws were very hard to loosen up and I needed to use WD 40 several times to loosen them,after that it was a snap for a 71-year-old woman.

Watched u tube video as supplied and followed instructions. Had trouble getting burners off so cleaned around edge of burners with fine bladed knife as suggested by other forum user and used oil filter type wrench to remove burner. There are three bumps on burner that hold it in place so need to turn anti clockwise to remove.

Two screws inside the exhaust box to take out the switch assembly and 2 nuts on the switch. Nothing to it

Remove switch cover with two screws ,remove two nuts holding switch in place ,remove switch,then reverse procedure with new switch.

Flip the breaker. Lift off the fan center grate. Remove two screws located on back of the burner dials housing. Lift the back of the housing, then pull this gently away from the front to unhook the front. Turn this over, locate the switch. Pull the three electrical plug connections from the switch plastic housing, remembering their locations. Back off the two nuts holding the switch to the underneath side of the dials housing. Place the new one in place, put it all back together.

remove two nuts and install new switch, then change wire connections from the old switch to the new one.
Then place it back together.

Still not fixed. Waited about a year for the part to arrive, due to "COVID supply chain issue". Part finally arrived and was missing a sub component (ironically the worn out part). Now awaiting a reorder confirmation that this is being sent along with a return mailing label.
The re-order required me to obtain a better picture of the part from your competitor's web site, to prove the part sent was defective as your site was inadequate. My first call on this issue failed because of an absence of the better picture.
The 2nd call to customer service was very understanding and professional but I have yet to receive any confirmation on this re-order in the past 5 days.

Removed Stove cartridge from stove-top.

Unfastened bottom screws, I recall 6.

Removed cover.

Removed two screws to igniter.

Used needle nose pliers to remove connectors x 2.

Had to drill to enlarge the mounting screws to new ignitor, then screwed it in place

Connected the two wires to each igniter.

Replaced cover n screws.
Reinstalled cartridge.

Bingo

I replace the igniter first that didn’t work so I had to order the wiring and then I replaced that there was a cover that I took off with a screwdriver took the wiring off and put the new wiring in it it was that easy.

Remove the 2 burner assembly by gently lifting the rear burner and pull towards the back of the stove and the entire 2 burner assembly will slide out. Turn assembly up side down, remove all the screw on the cover with a philip screwdriver and remove cover. Once opened, you will see the ignighter, remove the 2 screws holding it in place, remove and replace the ignighter and secure with two screws. Follow the 2 lead wires and remove and replace with the new wires, simply pull off old and push on new wires. Replace the cover and all the screws, slide it back onto the stove and you will have ignition! Simple install, takes about 20-30 minures. If both burners are out, this is probably the problem. If only 1 burner is out, you probably need to replace the stove burner spark.

First I did was to google the problem I have. There several video how to solve the problem. It show me different ways to solve my problem. I just follow the instructions. Thank to google without it, I am lost. I may add, that google is a big saver for me.
