Hi,

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.

Thanks
