F7 error message on GE oven

Send an e-mail to Charlie at hutchipop@yahoo.com for a fix-it that you can try. He explains a possible solution fully with his 'The Dreaded "F7" Error' solution. I actually found his information on another website when I did a web search for "GE Profile Oven F7 Issue". I sent an e-mail to him and he replied with free fix-it information. I am not a repair person myself, but, his instructions are very clear and simple to follow. I did the fix-it at no cost in approximately 10 minutes and it has solved my problem so far.

My oven is also a JT950 and the builder installed it in our home back in 2000. Our F7 issue started about 2 years ago. For a few months, "clearing" the panel and/or shutting the oven off at the breaker panel would temporarily solve the problem. About 1 1/2 year ago, however, the F7 would come on and continually beep. A repairman looked at the oven and replaced the control panel at a cost of $600 (ugh...). That solved the problem until a month ago when the F7 continuous beeping began again. There was no way I was going to pay another $600. for "temporary" repair and I was thinking of replacing the oven. Luckily, I came across the above-mentioned fix-it information and took a chance by following the simple instructions provided.

The insulation in the ribbon cable is poor. The conductors in the cable are crossed. The ribbon cable is actually two ribbons pressed together, and the conductors between the two cables are shorting or becomming crossed. Lift the two cables apart, place a piece of paper between them, fold the edges of the paper over the cable so that it does not slip out, and make sure to shove it all the way down to where it will meet the plastic display panel housing. There, problem solved.

7/31/09: had the same F7 code and beeping on my JT950 GE double oven. GE wante several hundred in parts and labor. Came across Charlie's fix. I emaile him and he promptly emailed me back a PDF with easy instructions and pictures on how to cure this problem. It is not equipment failure, but something known as "silver migration" of the ribbon strips (Google the term). In short, problem was fixed for FREE. Thank you Charlie.
