Thanks for the reply. So far my panel is holding out after some heat gunning. Fingers crossed.

Was your panel failing consistently prior to heat gunning? Based on what I have read in the forums, I had doubts that very many of the error messages are due to contamination/moisture affecting the touch panel surface or the pcb.Originally Posted by ei ei owe
Did you do anything additional to get your panel working?
So same error on single wall oven JJW3430DP01. Took apart, before i read this thread I figured it was the circuit board behind the control panel. found that on ebay and replaced. Same issue. Then I read this thread. I inspected the ribbon cable as posted here. Disconnected, reconnected and taped down securely with kapton tape. Clean with alcohol and deoxit. Same issue. There is a little ribbon cable to the left of that which was kapton taped down. It looked a tad not seated properly so i re connected that. Still issue. I then took my heat gun at 390F to the front panel (while on my counter) and pressed down rubbing it. This is first thing that solved it but only for a day. So the issue is the cap touch screen and likely some adhesive where that ribbon cable runs to. Not the board we can see. I see no easy way to get direct behind the glass to the cap touch area. surely they used adhesive so I'd have to heat a bunch and try to peel it back like removing a battery from an iphone. This is now more time than I wanted to spend so ordered the whole control panel here. Jenn Air now down a few rungs in my book.
Anyway, this thread shouldn't be marked as fixed.
I disagree that the thread shouldn't be marked as "fixed".
I have fixed mine. It has been working fine for a month now and has successfully rebooted after (at least) one power interruption.
One other member has also reported that their panel is now working.
Don't bother messing with the ribbon cables and connectors on the main board - that is not the issue - many others have also attacked that area with no success.
After 45 days without an issue, there was a power outage/glitch and the F2E1 error came back.
Since my simple mods to stabilize the 5V supply were not sufficient, I removed the resistors and connected the touch sensor boards to a DC-DC power supply fed from the 14V supply line.
So far, working like new.
btw - Don't bother with any of the previously described "fixes" involving cleaning the sensor boards with IPA or "heat gunning". There are no "stuck keys".
If keys were really stuck, the demo mode would not function.
The F2E1 error is caused by issues with the 5V power supply on the main logic board.

I ended up using the hair dryer trick. I have separate microwave and oven, and just the Microwave was giving me the stuck key error. Heating up the panel seemed to solve the problem (for now).
Specifically, the Tools button (left side) didn't seem to function. To determine which button wasn't working, I closed out the F2E1 error message, then repeatedly/rapidly pressed each of the three buttons several times: Kitchen Timer, Tools and Add 30 Sec while quickly closing out the F2E1 error each time it popped up. Of the three, the tools button made no sound while the other two beeped when pressed. So I figured the tools button was the problem area. With a hair dryer on high setting, I heated up this area (and everything to the left of the center clock display), then reset power, and viola it now seems to be working again. For how long, we'll see. I'll post a follow up in a few days.
If that doesn't end up working, I'll try eGuru's fix using the DC-DC 5v power supply. eGuru, if you can, please post which wires you ended up cutting/splicing into.

Power the supply from the the 3 wire cable. Feed +5V and GND from the PS to each of the touchpanel board feed wires (Pin 5 and Pin 1 respectively). For GND just splice onto the wire.
For the +5V make sure to cut the wires to isolate the mainboard from your +5V
@eGuru I have the same issue with my oven. Do you have any photos or details of what exactly you did? I just took of the control panel and I'm trying to understand which wires you're talking about.
Hey eGuru, any update or pictures regarding attaching a separate 5v power supply to the touch panel. I don’t quite understand how the 3 wire cable can power the power supply and what you mean by cut the the 5v wire after it’s watched to touch panel .
Thanks
Sorry, I don't have photos available.
I will restate the instructions with some mods.
1. Power the supply from the the 3 wire cable. The cable includes ground, +14V (approx), and a serial communication wire. Use a DVM to find the correct wires. Splice your power supply input wires to the ground and +14V wires.
2. There are short 5 wire cables between the main control board and each "touchpanel" board. Look at their connectors - a small molded-in triangle identifies pin 1 (ground).
Pin 5 is the +5V feed to the touchpanel boards.
3. Splice your PS ground (-) wire to the short cable wire that is connected to Pin 1.
4. Cut the short cable wire(s) that are connected to Pin 5.
5. Connect your PS +5V to each of the cut wires that lead to the touchpanel boards. Tape off the cut wire ends going back to the main board.
Good luck
If you look on the left side below the control panel, there's a metal duct that is supposed to conduct the air from the oven and vent it out. There is a fairly large gap that causes the steam to go into the back of the control panel. What I did was put the blow drying to that gap. The gap is below the control panel and above the top open door, right underneath the left side controls. After a day of no F2/E1 error, my husband got aluminum duct tape and taped the underside of the entire control panel and the duct [covering the gaps]. The vent hole is still open, to let the air out, but the gaps on the top where they didn't "fit" the vent duct exactly was taped. Hope this resolved the steam getting into the control panel problem.
What did you do to obtain "a day of no F2/E1 error"? Was it just using the blow dryer?
Yes. We actually took out the circuit board and panel, examined it. Everything looked okay. no corrosion, no loose wires. We put it back and immediately the F2/E1 error popped up again. At this point, we resigned that we might have to buy the part, but it is backordered. We then aimed the blow dryer from the top and sides before pushing the stove back. But that night the error came out again. That's when I started looking underneath the panel to see if there were any other openings from which I could dry the board. I saw that the metal had a gap where the vent comes out of the oven so I pointed my blow dryer in there. I didn't want to burn up anything so I kept it moving along the bottom, but mostly where the vent. It's been 3 days all clear. I haven't used the oven though, but will use the lower oven and hope it will be okay.
In my opinion, the error message is not due to a real key stuck situation.
When I first had the F2E1, I could go into demo mode and the error message disappears and the keys work.
I have resolved the problem (stable for several months now) by other means (per my previous posts in this thread).
I hope your modification actually works long term.
Our panel is smooth and does not have keys anyway. We taped any gaps on the bottom of the panel with aluminum duct tape, and so far, everything is good. I've used the oven and it's still hanging in there. Thanks!
Hey EGuru , I definetly want to try your solution but would much appreciate if you created a video outlining the steps taken. I’m sure this would help so many people getting ******* by ****** Jenn air products
