Error Code Condition Check/Repair Shop Parts
F2 Over-temperature condition detected If the oven actually overheated, the electronic oven control board likely has a stuck relay; replace the electronic control board. If the oven is at room temperature, the oven temperature sensor could be defective. Disconnect power to the oven and measure the oven temperature sensor resistance using a volt/ohm meter. If the resistance isn't 1100 ohms at 72 degrees F, replace the oven temperature sensor. If the resistance is correct, replace the electronic control board.
