    Jenn air sucks

Rather than going down to the basement every time, I installed a momentary off button using the blue power wire going to the panel. That resets the error and it lasts a couple days. Another idea is to leave the microwave door cracked open at night. The light may provide enough heat to keep the panel warm enough to prevent capacitive layer contraction. I’ll try that for a few days and report back.
    After cleaning and heating many timed, i finally hot a replacement panel on ebay for $300.
    Have to be carefull to match numbers since similar panel used for wall oven or double oven and combo etc.
    New panel is Rev C and works great.
    Fast forward, micro wave ok but now wall oven is same stuck key.
    Doing the cleaning and heating
    It is obviously a calibration setting that is wrong in the micro code running the panel.
    So it thinks a key is pressed when nothing going on.
    Replacement panels probably have updated code.
    Jenn air should replace panel and recycle by updating old panel.
    Watching for new oven panel now.
    Meanwhile heating and cleaning are in the works.
    Mayby look into the connector thing also

    JennAir should be ashamed.
    Maybe we need a TV expose of poor customer service
    Flood internet with pictures of Lemons hangjng on ovens

    We unfortunately also just joined the F2E1: Stuck/Shorted Key club. We are in Canada...
    When we called they told us that Jenn Air has discontinued making the panels, so we now have to search for a 3rd Party one.

    Hi everyone I joined the F2E1 club about two years ago when both my wall oven and separate microwave oven started pining/flashing the error message. The microwave panel was replaced under warranty a year before and it still failed. I was planning on bypassing / hijacking the signals from the touch panel buttons and mimicking them with a WiFi enabled microcontroller (was thinking ESP32 or a raspberry pi) but in my testing/diagnosing I think I stumbled onto a solution. The solution hasn’t been time tested yet (it’s been about a week) but it seems to be working. I wanted to share it with this great group of problem solvers in the hope that it helps someone.

    THE SOLUTIONION: splice/solder/shield in 10 ohm resistors (not 10k ohm resistors) to each of the wires on connector harnesses for the left and right button panels. See pictures below. You will need to do this to all ten wires. I tried a combination of doing some/not others and had consistent, error free resulting by doing all 10. The only drawback is that the lighting for the buttons is effected, some dim, some come on/off, some work just fine but in the end no error messages, and all functionality works. If above is not clear, let me know, I can provide more information.

    How I got there: As I mentioned, I was planning on high-jacking the signal and driving the button functionality with a wifi controlled microcontroller (then using a webapp on my phone to “push buttons) and/or add external physical buttons to mimic the functionality. When I setup a “test rig” using a breadboard (see below), the panel started working. It turns out that adding the extra wires, created about 10 ohm resistance on the lines and that seemed to do the trick. Anyway, good luck hacking and reach out with questions. Happy to help if I can.

    P.S. I will post my specific wall oven and microwave oven model numbers later if that is helpful.

    Has anyone tried the above procedure? I'm willing to hack in if it saves my board.

    Jake - hope you log back in some day and tell us how that's been going - I am very curious to see how that's been working out. It's a ton of work it seems but if it will save my customer (who can't really afford a new oven nor a control board right now) then I might give it a shot. It's not like they can use it right now anyways.

    Appears that I have joined the club! GRRRRR. My Jenn-Aire wall oven model number on the little paper in the upper door trim is: JJW3430 (no letters or numbers afterwards) Serial number D.9.0.4.1.0.6.2.5
    But this forum is the most informative that I've found regarding theF2E1 defect. Ours did it overnight. I really like the wall oven and the failure and then learning that it's a very common failure was a complete surprise!
    We bought this house and moved in on April 1st, 2024. There was a complete kitchen remodel in 2019. That's 5 years! Maybe in warranty? Dunno. I'll call and beg. I have no paperwork. The previous owner that had the kitchen remodeled didn't leave any paperwork. I think the kitchen remodel was finished in 2020; so I may be in luck.

    In the meantime, I'm going to follow the advice given here as long as it doesn't break any seals or tags that would void the warranty. I'm not helpless around electronics, ham radio operator since 1963 and home-brewed most of my equipment. Then, computer technician for 12 years ending in 1983. I consider myself to be fairly competent fixing things. (It's what I do, even at 76 years old).

    Ken, sorry to hear about the failure. I highly doubt 2019 models will have warranty of any kind. In the past when I've called to weigh out my options with customer service, the option was to purchase a new panel and then also purchase the annual warranty "subscription." I can't remember the exact price but it was pretty steep for an annual fee. There's absolutely no care of any kind given to this repeat issue. I also like my oven when it works properly which is never!
    I have found that shutting the breaker off and then heat gunning the front of the panel for a couple of minutes will temporarily restore my functions but not last long. When I heat gun I'll set a delay start for the lower oven and it will work fine until the cycle ends. then it's demo mode to silence the beeping.

    If anyone has found a repair or a store that repairs these panels, please post.

    Good luck

    Hello, Doc Ryan. I hope you can help.
    I just learned that Jenn-Aire only has a TWO YEAR WARRANTY, which doesn't cover my touch panel since our oven is 4 years old. The factory support had nothing to offer me in the way of repair except to call out a repair service. I turned that down.

    My oven's model number is JJW3430DP Serial number D.9.0.4..10.6.2.5 (as printed on the tag in the door frame).

    I've tried the tricks to get the touch panel to work that I read about here. No luck. It's apparently kaput.

    What would be the price to get one from you?

    My other alternative is to bite the bullet and buy a whole new wall oven. I'd rather not, we like this one . . . but not so much now that it doesn't work any more. It worked fine one evening and the next morning broken.

    Ken

    Hi Ken, your model number is missing the last two numbers but it looks like they all use the same control panel linked below.

    Control Panel Assembly (Stainless) - W11087468 (PD00085680)

    While sitting here, I entered a chat with Parts DR.
    The operator couldn't help me without the last two numbers. I was able to take a readable picture of the tag on the door frame.
    With that, the chat gave me a price for a new panel.

    I've been in electronics for 60 years, but uneasy about purchasing a thousand-dollar part with no return option if I plug it in and it doesn't work or doesn't help me.

    Looking for alternatives unless I misinterpreted the return policy.

    That is correct, we do not return parts that have been plugged in or installed in any way. We cannot return and resell those parts to other customers. The part does come with a manufacture's warranty against factory defects.

    Yeah, with that in mind, I have purchased a new LG built-in Wall Oven. Whole new oven with 3 year full P/L warranty for only a few hundred dollars more.
    I just can't risk $1,000 based on Internet information; even though I have a lifetime history of repair service for myself and my company of 25 years.

    Thanks for your attempt to help. I understand that you are in business and need to have policies. No hard feelings at all. It is what it is.
    I probably won't buy another Jenn-Air product. I really liked the performance and aesthetics of this one; but they are apparently weak, break often, and have poor warranty coverage. Way too costly to repair.
    Too many disgruntled consumers for exactly the same problem convinces me to stay away.

    Doc Ryan-
    Having the same problem. What's the appropriate replacement panel number for JMW3430IL02?
    Thanks
