Oven control board failure
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 oven control board. (The oven control board includes the key panel on models beginning with 664.9511.)
Keypad disconnected
Unplug the range or shut off the house circuit breakers for the range to disconnect electrical power. Reconnect the ribbon wire between the key panel and the oven control board if disconnected. If you find the ribbon wire plugged in securely, 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.)
Stuck key
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.)
Oven temperature sensor failure
Unplug the range or shut off the house circuit breakers for the range to disconnect electrical power. Measure the resistance of the oven temperature sensor. You should measure between 1,000 and 1,200 ohms at room temperature (77 degrees F). If resistance falls outside of that range, replace the oven temperature sensor.
Oven too hot
Unplug the range or shut off the house circuit breakers for the range to disconnect electrical power. Measure the resistance of the oven temperature sensor. You should measure between 1,000 and 1,200 ohms at room temperature (77 degrees F). If resistance falls outside of that range, replace the oven temperature sensor. If resistance is within that range, replace the oven control board because a stuck relay on the control board caused the oven to overheat.
Cooling fan speed too slow
Unplug the range or shut off the house circuit breakers for the range to disconnect electrical power. Check the wire harness connections between the cooling fan and the oven control board. Reconnect any loose wires and repair any broken wires. If the wire harness connections are okay, replace the cooling fan. If the problem continues, replace the oven control board because the board isn't correctly detecting the fan speed.
Cooling fan speed too fast
The hall sensor (tachometer) on the cooling fan could be defective. Sometimes, a defective oven control board causes this failure because the board doesn't detect the hall sensor speed signal correctly. Unplug the range or shut off the house circuit breakers for the range to disconnect electrical power. Replace the cooling fan. If the problem continues, replace the oven control board.
Miswired power cord
Unplug the range and check the power cord wire connection on the terminal block. Connect the wires correctly to the terminal block as shown in the installation guide.
