I just found this exchange and now feel better, as I thought the GE curse was just on my kitchen and oven. Have a 9 year old GE profile double oven (convection). Had the first f7s a few years ago (after doing the self clean which clearly set something off). The GE repairman at the time actually gave me (what I now realize) is an extra control panel. There was clearly an inkling of a design flaw then.' Fast forward to Sept 06--the beeps started all over the place. Found a good local appliance co...the repair guy came and was a little baffled...suggested that we replace my old control with the one I had in the box from GE and see what happened. Oven worked for l0 days then f7 again. I did find if I turned off the circuit for a couple of hours and then on again, my oven worked! (I also ran and baked up a storm the other night when that happened). There is an engineer in Missouri who has a great suggestion, but I lost his email. I am faced with the holiday weekend, no oven and a renewed pledge NEVER to buy a GE product again. I wasn't going to last time, but this is it. I will gladly join in or help coordinate any class action, if one doesn't exist already. They clearly are making money on the replacement parts (which usually do not work) for this defective design.

I too encountered the F7 error on my four year old jtp56.  After reading several posts I disconnected the keypad, and guess what, I then recieved an F0.  Great, I believed from reading the posts that both the ERC and keypad would need to be relaced.  Being an electrical engineer I thought that this needed more investigation (I like to replace components, not entire boards.)  I could not find a short in the keypad, although I did find that pins 7 & 13 are normally crossed.  I re-attached they keypad and guess what, no F7 or F0.  I believe that by messing with the keypad pressing buttons in a horizontal position temporarily fixed the short.  I have ordered a new keypad as this will definately fail again. Here I get to my main point, no F0, and the oven works fine.  How could this be?  Electronics as basic as this do not fix themself magically.  I disconnected the keypad once again, and what did I get, an F0.  I crossed pins 7 & 13 on the ECU with the keypad disconnected and did not recieve an F0.  What does this tell me?  That the ECU has several meanings for an F0, one of them being a disconnected keypad (by monitoring pins 7 & 13).  Personally, I would hate to buy and ECU when none is needed.  Time will tell for sure if replacing only the keypad fixes the problem, but I'll be that it does.

So far, new keypad only and no F codes.  cdwasher - If you feel comfortable, find the schematics for your oven, then find the keypad pinouts.  If they show that pins 7 & 13 are normally crossed, turn the breaker off to your oven, cross them using a thin wire, then power back on.  If you do not know how to find pins 7 & 13 don't try this.  If you look at the ribbon cable, pins 7 & 13 are the same two no matter what end of the connector you count from.  If you get no F0, then I would try only replacing the keypad.  On a side note, my 4 yr old ge dishwasher doesn't drain, it leaks and the wheels fall off daily.  My 4 yr old ge microwave has a bad turntable.  Never again will I buy ge.

I've had same problem for about a year on a JTP56Bxxx.  The first time I pulled the ribbon cable and used an eraser to clean the contacts.  Fixed the problem for six months.  Repeat process and fixed problem for three months.  I'm on my fourth or fifth ribbon cleaning, using alcohol now.  Always seems to fix the problem temporarily.  The last time I was in a bit in a hurry and just pulled the cable out and stuck it back in within 3 sec.  The whole job took 2 mins and the oven is still working.   So why is it that cleaning the ribbon cable can fix a defective keypad or ERC for six months.  Could it be that the contacts between the cable and the panel are of incompatible materials causing a corrosive exchange of (what ions or something?).   Otherwise how can a defective keypad/ERC work fine for months at a time if they're defective.  Doesn't make sense, and the passing of time between failures seems to be the variable that spells corrosion. And belive me, before I plunk down a couple hundred bucks for a GE part, I'll be looking for another oven (NON-GE) .  Oh did I mention I have a GE profile refrig that keeps freezing up the water dispensor and vegetable drawer  (only in the winter of course).

I have a JT950AA GE Profile double oven that has had the sam F0 and F7 error codes.  The oven has been giving these error codes for about the past 18 months.  I have been doing the trick of turning off the breaking and keeping the power off until I need to use the oven.  When I turn the power back on I can usually use the oven for a few hours before getting the errors. I researched this problem on the interent and found a reference from a Mr. C. Popeck.  I emailed him and he quickly responded with an easily applied fix.  I used his piece of paper fix and that seems to have finally resolved the problem.  My oven has now been energized for about a week with no error codes.
