I have to turm the oven off at the braker box. it comes on by itself. when I turn it on to cook it will not stay on gos off and beeps. Shows C7 or F7

this code means either a stuck control pad or a faulty control board/display board... one thing to try is turn power off again at breaker and run your hand over all the keys on the control panel firmly pressing each key sometimes you can luck out and free it up if that is the problem and reset power if it starts again you will have to gain access behind the control panel and unplug the ribbon cable to control panel.... if it stops after you unplug ribbon cable most likely it is a bad touch pad assembly if it continues you most likely have a stuck relay on the control board and will need to replace that... i have see the fault require both the touch pad and control board ,but hopefully this will help you ..i assure you it is one of the 2 problems ... g.e servicer for 18 years now and a common problem most of the time happens after a long cooking period or a self clean was preformed recently...
GOOD LUCK

how do we operate

Hello,

These codes mean that the oven's electronic control has detected a condition it needs to check. When you see a code, follow these steps:

• Press "Stop/Clear" to clear the display and stop the beeping.
• Reprogram the oven.
• If the code still displays, turn off the power to the oven at your breaker box and wait five minutes before turning it back on

thanks.

This indicates the ERC Electronic Range Control has failed. First check the key pad. Press each button one at a time. You should feel or hear a click and feel the retraction. If any button is not working the problem is likely in the key pad. If all seems good the control is at fault. Check to see if you have power going into the control. If you do and nothing is working the control board or ERC needs to be replaced. Here is a link for checking and replacing an oven control. If you need diagrams and illustrations of your specific model enter your model their. All parts come with installation instructions.

F7 stuck keypad
Stuck keypad may mean relay is turned on.
Determine if problem is with the Key Panel or Control by:
1. Pushing CLEAR/OFF pad.
2. Disconnecting Ribbon Cable from control and waiting at least 32 seconds to see if Code recurs

If code recurs, problem is in the control. Replace control.

If code does not recur, problem is with the Key Panel.

I have a GE JT950 double oven that just did the same thing: F7 and beeps like crazy. I found solution on another post: an engineer figured out how to solve the issue without calling GE or buying parts. I just did it tonight and it worked fine. Here is a copy of the post:

Send an e-mail to Charlie at [email protected] 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

One of the most common problems with GE electric built in ovens is the error code “F7′ shown on the display. I’ve seen it many times before and today I had a service call for the same problem again. The error code “F7” will be displayed along with a beeping sound if the ERC (Electronic Range Control) or “clock” senses one or more buttons on the control panel stuck. It could be displayed in any mode: “cook”, “clean” or even more often in the “time of the day” mode. In order to fix it, the control panel has to be replaced. This is a very simple job and you will need just a 1/4′ nut driver and a Phillips screwdriver.
To get the right replacement part just click on the link AppliancePartsPros then type the model number of your oven (it is located at the bottom left corner on the door frame of the lower oven) in the search box, click on the “search” button and in the new window type the word ”control panel” in the “search by keyword” box and click the “search” button.
Always turn off the circuit breaker first.
Open the oven door (if you have a double oven, it should be the upper one) and remove three screws (on some models just two on corners) from the bottom of the control panel. If the control panel on your oven is made of stainless steel, then you have to pull the oven out of the cabinet for about 2′ to 3′ to get better access. Pull the control panel forward and up to remove the tabs on the top of the frame, out of the holes in the end caps. Pull the control panel out and turn it about 90° toward yourself (the face of the control panel down). Unplug the control panel ribbon from the ERC. Remove four screws holding the ERC to the control panel. On some models you also have to remove the screw which attaches the ground wire to the control panel. Let the ERC hang on its wires, remove the old control panel and replace it with the new one. On some models before you do it, you have to remove the end caps and the bottom shield from the old control panel and install them on the new one. Do not forget to plug the new control panel ribbon into the ERS slot. Attach the new control panel to the oven and turn the circuit breaker on. Set the time of the day and you are back in business

f7 is a shorted key-stuck function on control

The F7 represents a shorted matrix or start key. To determine whether it's the key panel or control itself, disconnect the ribbon cable of the key panel that goes to the control and power the oven up. If the F7 does not come back, it's the key panel, if it comes back, it's the control..
