Press down and around all keys on the keypad to free the stuck button. Unplug the range or shut off the house circuit breakers for the range to disconnect electrical power for 30 seconds, and then restore power to range. If the code reappears after restoring power, disconnect power and replace the key panel. If the problem continues, replace the oven control board. (The oven control board includes the key panel on models beginning with 664.9511.)
