Many ovens built by GE display error codes on the display when problems are detected. The F7 error code indicates that there is a problem with the buttons of the control panel. The code comes on when two or more buttons are stuck at the same time. The oven cannot operate when this condition exists. The oven is repaired by replacing the control panel with a functioning one.
Unplug the oven power cord from the electrical outlet.
Open the oven door fully.
Unscrew and remove the two or three screws from the inside of the oven that hold down the control panel.
Pull the control panel toward the front of the oven. Lift the panel up to disconnect it from the oven.
Rotate the control panel sideways to get easy access to the data cable.
Remove the screws that hold the data-cable connector. Disconnect the data cable. Set the old control panel aside.
Plug the data cable into the new control panel. Replace the screws that hold the cable connector into the control panel.
Position the control panel in its correct position on top of the GE oven. Replace the screws on the bottom of the control panel from the inside of the oven.
