F7 - Function Key Shorted or Stuck - Replace touch pad, or touch pad and control board (clock) if one assembly.

Hello & Welcome to FixYa

F7 error code is displayed when the clock assembly/electronic range control (ERC) goes bad and needs replacement. Please get back to me if you have any other questions.

F7 A = Function pad button stuck or
B = Bad clock Unstick button or
Replace Electronic Range Control (ERC)

HI, this is an issue that concerns either the key pad or the control board.

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.

Hi there,
Well, F7 error code occures due to
A = Function pad button stuck or 
B = Bad clock Unstick button or

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.

Good Luck!!

It looks like you have a function button pad stuck or a bad clock.

Unstick button or replace electronic range control.

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
