Touch pad for the oven does not work

It's most likely that the error code you are seeing is F1, not F7. F1 is a code for 'stuck touch pad'. You will need to replace the clock/ERC or the touch pad (or both).

F7 code is 'shorted matrix or start key' could be due to a problem with the key panel or control.

Hello there
The code can be caused by a faulty keypad or a Stuck keypad which 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. :

F7 A = Function pad button stuck or
B = Bad clock Unstick button or
Replace Electronic Range Control (ERC)
Try gliding your finger flat across the keypad rapidly and see if you can unstick the key / touch pad. Usually once this code appears it will repeat.

On self cleaning ovens this is the service check:

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.

Thanks for using FixYa!

You have a stuck keypad or a bad electronic oven control. Try pressing all buttons at random several times each to unstick a faulty pad. If that does not work the EOC must be replaced.

Hi
On a GE range oven F7 indicates either a function pad button is stuck or the clock on the oven is malfunctioning

On the 99 Range oven F7 indicates a shorted Clear/Off Key due to membrane switch or a shorted control or connector

On the GE XL44 Self Clean Oven F7 is Stuck keypad or control relay malfunction

hope this helps

Have you inserted the card as described in the solution?

HI, you will need to replace the touch pad or key pad asap. it has failed.

Hi there,
Well, F7 error code occures due to
A = Function pad button stuck or 
B = Bad clock Unstick button or
Replace Electronic Range Control (ERC)

Replace the ERC there are ten screws 3 on each side and 4 on the control leave the hex screws alone all you need is a phillip screwdriver.
REMEMBER TO SHUT OFF THE POWER FIRST lift and fold out the control panel remove the ribbon cable and remove the four screws that hold the control board . replace control panel in reverse order.
Best of luck!!
Thanks

For a temporary solution, put a magnet over the "clear off" button. I used just an ordinary refrigerator magnet and it stayed off
