JEC8430ADW Jenn-Air Cooktop - Instructions

My grandson, age 15 did the replacement. Now, how easy is that!

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.

Unplugged the power cord first. Opened oven door and removed the two screws that held the stove top glass down. Lifted the glass top and removed the four wires connected to the element. I taped the wires to the lid in the pattern they were attached to the element. remove the element from the brackets. The new element was an exact match. reversed the sequence. Put a pot of water on and boiled a hot dog! Perfect! Great part and speedy delivery!!

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

1st - UNPLUGGED appliance from electrical source!! then removed screws to open ceramic stove top, disconnected wires from dead element, plugged in wires to new element, closed stove top, turned on burner - it worked!!

only problem is that "hot burner indicator" does NOT stay lit after burner is turned off!

Only hitch I experienced was identifying the correct replacement. The original diagram presented the accurate shape of the element my range required. However a different shaped element was displayed when I noted my unit is a series 12 serial number. I ordered it (with reservations) and as it turned out the replacement was identical to mine. Next time I will have a lil more confidence in the instructions given.

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

This is a slide-in range, so I:
1. Turned off the circuit breaker for the range. The range is hard-wired, so can't just be unplugged. I determined the clock on the range went off.
2. Removed 4 screws holding the front control panel to the cooktop. Removed 2 screws from each side panel into the cooktop. Removed 4 screws from the rear panel holding the cooktop.
3. With my assistant (my wife) lifted the cooktop and tilted it so that I could access the underside.
4. Used an iPad to take photos from several angles of the wire connections from each burner control. Printed the one showing the connections on the dual burner control.
5. Removed the 4 screws holding the sheet metal support for the dual burner and one of the other burners. Released the spring steel retainers holding the dual burner. Removed the burner.
6. Used the iPad again to take photos of the connections to the dual burner, and printed it.
7. Removed all the wire connections to the burner. Checked continuity from the center (common) terminal to each of the other terminals. Determined that in fact the inside coil was open (burned out).
8. Removed the two screws holding the spring clip retainers on the old burner. Matched the old and new burners to determine where the spring clips should go. Drilled 2 small holes in the base of the new burner and screwed the clips from the old burner on the new one.
9. Now the tricky part: The new burner didn't have the exact same limiter and heat sensor probe as the old one. After several false starts, we were able to barely make out the terminal letter/number designations on the control and match them to the same letter/numbers on the new burner. It required a magnifier and a strong flashlight to read these engraved markings.
10. Made the connections on the burner. I used a pair of long-nosed pliers to carefully pull the connections off the spade terminals, and attch them on the new burner.
11. Mounted the burner to the sheet metal support using the spring clips previously installed.
12. Re-attached the 4 screws holding the burner support to the cooktop.
13. Carefully replaced the cooktop onto the range, paying special attention to not pinching any of the wires, and making sure all the wires, from all the burners were still connected.
14. Replaced all 12 screws holding the cooktop to the range.
15. Turned on the power, and checked all burners, including the new one, to see if they were opetating properly. YAY! They all worked!

It must be noted that we had to call a repairman to troubleshoot our installation the first time. We had reversed two of the wires to the new burner, because of the difference between the old and the new limiter connections. The engraved markings in the porcelain were very difficult to see. The instructions that came with the new burner never addressed this issue, and instead had very confusing (and worthless) instructions about replacing the limiter from the old burner to the new on. (This was not possible, anyway).

After the repairman left, we discovered the front burner that had been working, no longer was. With our newfound experience, we repeated the previous steps to take the range apart and discovered one of the wires had become disconnected from that burner. We re-connected it, re-attached the cooktop, and everything worked.

One telltale indicator that we had mixed up the connections on the burner, was the red "hot' warning light on the range top came on as soon as we restored power, even though no burners had been on. I should mention that the dual burner "worked" a couple of times even with the reversed connections, but then failed to work any more.

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.

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.

This is a two module cook top That I have, 2 burners in each module. I took it apart take the damaged one out and replaced with the new one, put it back together and turn it on. Heeeyyyy it works. Thanks.(and I'm not an electrician)

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

One important note is you can't buy the control for the right front burner (Custom Control) by itself. This kit included both the burner, control and wiring harnesses. This is a retrofit, I am assuming a known problem with the original design. This repair requires the cooktop to be removed from counter, turned upside down, and disassembled. It comes with a 45 step instruction sheet thats pretty good. Let me point out a few things that are helpful: 1) The screws to attach the control to the switch plate are too short. These are 8/32 screws 1/4 inch long. I had to go to the hardware store and buy two screws 3/8 long and cut them, since 3/8 is too long of course. Follow directions carefully, you need to remove the bottom cover and fan to disconnect it before taking the burner box completely off. The shaft of the new control is shorted than the other controls so you need to put a "filler" in the burner nob. THey suggest you use the rubber gasket from the old switch so make sure not to throw it away. One other note, since this is a retrofit, you need a drill. You need to drill out two slots in the switch plate to mount the new burner control. Good Luck.
