It seems you have a stuck button. Here is a list of fault codes:

SOURCE: panel light is out

There is a capacitor on the clock board labelled C3. It will probably have brown burns on it or "syrup" leaking around the base. You can buy a box of 10 of these for 75 cents at Radio Shack (make sure you match the label on the old capacitor, I think it's 58mf and 35V but I could be wrong) and a pencil soldering iron for $10. It's held on with 2 little wires. Before taking it off note capacitor orientation (where the blue +++ stripe is), the replacement has to go on the same way. Common problem and easy fix.

SOURCE: LED Display fading

As noted in solutions to other Jenn Air ovens, this is often solved by replacing the capacitor labeled C3 on the circuit board that contains the display. Oven heat apparently causes it to fail over time. This is a solder connection to the circuit board. Not hard if you have any experience with this kind of soldering it is straightforward.

Seven phillips sheet metal screws to remove panel assembly, plus two electrical connectors. One ribbon connector from touch panel to board, then four 1/4 hex sheetmetal screws to remove circuit board from touch panel and metal frame. Then soldering iron.

It did work on a 40300 dual unit, which is same as this model except for cosmetics.

Capacitor is 35 volt 68 microfarad. Radio shack has 100 microfarad, which one report says works. Radio shack doesn't have a 68, but they do have 22 and 47 which mounted in parallel give 69, which is within tolerance. That's what I used. The capacitors cost $1.29, less than 1% of the cost of a new circuit board.

SOURCE: Jenn-Air JJW8530 LCD panel does not light up

BrianGem posted a great solution back in May of '08, I just completed that fix on my own Jenn air, took me about 30 minutes once I got the correct capacitor.
The display board apparently has a weak spot in the
design, most likely heat related, (probably low priced components from offshore sources)
Fix: Replace heat damaged capacitor labeled C3 on display board, Hard part will be obtaining the 35Volt 68uF capacitor, I'm lucky enough to have a Brother in the electronics design field who found me a couple of high reliability caps designed for hot applications, He does not recommend changing sizes without design review for fear of overloading another component, however several other posts have indicated that a 35V 100mF cap has worked fine for them.

My control panel was attached to the oven with 4 screws accessed from above the top oven door, the panel slid up about 1/2 " and lifted off, Unplug the ribbon cables and the panel can be removed to a convenient work surface. The display board itself is mounted with 4 screws and connected with a wide flat ribbon cable, the suspect capacitor is surface mounted to the reverse side of the board, two plastic clips need to be released (gently) and the ribbon cable unplugged. Capacitor is likely discolored or leaking, Using as small a soldering iron as you can find De-solder it and replace with new, match polarity marks and don’t use any more solder than needed.
If you run into trouble drop me an e-mail to and I’ll try to help.
Good luck.
Thanks for this site..

SOURCE: oven digital display not working well

I got your fix no prob. This is going to cost you a buck fifty, that's $1.50, I say it dollar and fifty cents! Got your attention yet?
Here's the solution to a dim display or non working display when the oven otherwise works.
1. Turn off your circut breakers to your oven, then remove the display and control panel via the screws you see on the top or underneith. There will be about 4-7 screws based on your model oven. You'll pull it either up or down depending on the model by grabbing with both hands on either side of the panal after you have removed the screws. 2. Carfully remove the three or four ribbon cables connecting the display panal to the oven electrically. This should be done carfully and only after the power is shut off to your ovens by the circut breaker or unplugging them. 3. Pull the display panel out by unlatching the black plastic snap holders. Using a soldering iron (costs about 15 bucks at radio shack), remove the C3 (68uF 35V) capacitor from the board. Replace it with the 100uF 35V capacitor from radio shack or digikey for $1.50 +tax. If you don't know how to solder, well you can learn for about 15 minutes of your time, or you'll have to resort to paying your repair man over 300 bucks to fix it himself and the best part. HE CAN'T SOLDER EITHER! He'll replace the whole display LCD because that's the most profitable choice for him and Jenn-Air/Matag. 4. After getting upset at how easy this fix was, put the oven together and rejoice that you just fixed your display problem for less then 2 dollars and about and hour of your time considering the search the brought you here. Cheers to you and to me for letting you know about this. Share all the knowledge you have with others. It's free money!

Jenn air oven will not heat you push bake and it says 100 but never heats up

One side of your 240 volt connection is disconnected, most likely in the plug wire connection. The neutral and one leg of your 240 is working thereby your display still works since it runs of 120 volts. Happened to me I had one wire come loose from stress on the plug

Oven digital lighted display is dim

You need to replace the C3 capacitor on the control board

You can replace only the C3 - it is 68uF / 35V and you can go to Radio Shack and get their part # 272-1028 - 100uF/35V one. It takes all but 10 minutes to re-solder the new one in place
