You can try to fix the error by disconnecting the electrical power and replacing the electronic control board if the appliance is overheated due to the defective electronic oven control board. If the code appears when the oven is not overheating, disconnect the electrical power to the oven and check the wire harness connection on the lower portion of the oven temperature sensor. Ensure to reconnect any loose wires or replace the wire harness if it is damaged. If it shows that it is okay, check the lower oven temperature sensor resistance by using a multimeter. Also, it must have 1080 ohms of resistance at 70 degrees.
