F7 is a shorted key error
It can be caused by one of 2 parts either the keypad or the control board.
See Section 4 is the parts above.
Item 2 switch-membrane is the keypad. Note that there are different colors.
Item 3 is the Electronic oven control assembly

Most of the time it is the keypad that is bad.

One way to check it is to use a meter on the ribbon cable to see if a key is always closed. Unfortunately the manual does not give a pin-out for your unit and I am not sure that one on Page 1-16 for a SVE47600 is the same as yours.

You could unplug the keypad ribbon cable and then give it a try if the error does not come up again odds are high that it is the keypad.

Be sure to remove power from the unit when doing this.

Does this narrow down what the problem is?

That does sound like more of a control board problem than a keyboard problem.

I would still try cleaning the contacts.
Also I would check the solder joints on the board for a bad one.
Cold solder joints are often a gray instead of silver color.
Wiggle the capacitors (small cans) a little while watching the back side of the board. If the leg moves then tou have a bad solder joint.

I found this on Applianceblog

I reviewed the service manual which states,”remove the four hex head screws from the bottom of the control panel. Grasp the panel by the sides and pull out and down”. I also removed the two side trim pieces to confirm there were no screws there…none. When I pull on this I feels as though something still has a hold of the top center (over display) and I don’t want to break it.
I’ve read posts where everyone says how easy this was to do in 5 minutes. Perhaps someone who has done this recently knows the trick and would share.

For the benefit of future folks looking here I will explain. According to the service manual, "remove the four...(see above post)". What they fail to inform is that behind each knob is a screw holding the control to a bracket screwed to the frame. Once the four lower screws were removed followed by the screws holding the knobs in place the control panel slid right down. Replaced the clock in about five minutes, replaced the screws and danged if it don't work.

I have been disassmbling the removing the switch panel and cleaning the contacts since I first wrote asking for help. That worked until the latest attempt the alarm fault code kept coming on so I decided tho finally buy a new Switch Membrane keyboard. I installed it today and everything worked fine except the cancel off key. So now I can turn the oven on but I can't turn it off. Did I do something wrong or do you think the membrane keyboard is defective?
