Your problem is most likely caused by a short between sections of the ribbon cable between the touchpanel and the electronic control. The solution is to insert a slip of paper between the sections where it exits the touch panel. See the attached photo. If you have a metal touchpanel, insert slips of paper on either side of the ribbon cable as well. CAUTION: Be certain to turn off the power to the oven before you poke your fingers in and around the touchpanel. My solution has worked for hundreds of folks. Don't worry about the paper burning.

    Here is the photo showing my solution. I have now shared this solution with over 800 individuals. Most report success. This problem is caused by a design defect in all GE and Kenmore ovens.
    The technical name for the problem is called Dendrite growth. Many electronic devices have failed because of this well known problem. GE could have prevented this problem for only a few pennies. Do a search on GE oven F7 to learn more about this wide spread problem.

Looking for two year for this solution. Piece of card behind the ribbon and I cleaned the contacts just to be sure. After years of random F7 in the middle of the night, it all works perfectly again. Thanks so much. Saved key panels and electronics replacements.

    Follow up to the paper solution.  After inserting the cards where shown, I also had some errors F7, F0 occasionally.   After some testing, the error quit immediately after pulling the panel out slightly.  I looked and my ribbon cable appears to touch the electric light terminal for the top oven light.  I put a piece of shrink tubing over the lamp terminal to insulate it from the ribbon cable.  So far the problem has stopped.   For those with continuing problems you can look for another contact point such as the bare terminal on the light fixture (top oven in a GE wall mounted unit).

    That's it!  Not only was the paper required per original post but on mine the above insulation of the light bulb wire behind the ribbon cable was also needed.  Since then I have had no more F7s.    If anyone having F7 then also check where the ribbon might be touching a wire when the panel assembly is pushed back into place.  This ribbon was rubbing up on 110v lamp post wire.  Wherever that cable might touch something just protect it and F7 be no more!

F7 alarm

EVERY failure code schematic i look at on maytag states that if your getting a f7 code then your keppad has failed or is stuck... make sure you turn breaker off for approx. 30 seconds and run your hand across touch pad firmly pressing down on all the keys... reset breaker and try again... if it still faults then you are going to have a bad touch pad... be warned though the touch pad does have a ribbon cable that connects to the control coard and it is possible it has shorted control/display board as well... hope this helps you out ...appliance servicer for 18 years

We had a power outage and when the electricity was restored the oven is displaying an F1 and F7 code and is beeping the alarm, how do i stop this?

Hello, the F1 error code means internal logic failure (monitoring function) it sounds alarm and inhibit cook mode You can fix it by replacing the electronic range control (ERC)

F7 error code means the function key shorted for over 16 seconds, check for something pressing a key or preventing normal release of the key. You can fix it by replacing the electronic range control (ERC) if other component check normal.

Stove is continuously alarming and flashing ''F7'' what does that mean? And how do I stop alarm sound?

On some Jennair's this means that there is a stuck key on the keypad. You need to post the model number to be sure.

F7 shows on display and display getting dimmer over months

Dim display is TOTALLY independent of F7 error.
The display will dim as the display board capacitors wear out - due to the heat. Replace the capacitors on the display board (see my other posts) and your be able to see the F7 error code as bright as can be!

F7 alarm

F7 stands for a faulty touch pad, faulty clock or both. Usually it's the touch pad. Most manufacturers recommend replacing both of the components. First, because they make more money that way, and second, it's the easiest (although more expensive) way to fix this problem. If you'd rather try and save some $$$, you can perform the following test and hopefully identify which of the two components needs to be replaced. The test... Disconnect the power to the oven before performing any repairs. Something triggers the clock to display F7 error code. You can unplug the touch pad from the clock and see if F7 comes back on. If it does, the clock is bad. If it does not, the touch pad is bad. Hope this helps, APP tech
