Remove the oven temperature sensor probe and disconnect the two wires. The temperature sensor probe is likely removable from inside the oven cavity. Remove the two screws and slowly begin pulling the sensor out until you come to a quick disconnect plug. Disconnect the sensor plug and then insert one meter lead into the terminal of the temperature sensor plug and place the other meter lead into the other terminal of temperature sensor plug. Place the dial on your multimeter to 200K as shown in the image below. The temperature sensor probe should measure 1091 ohms plus or minus 5.3 ohms at room temperature of 75 degrees plus or minus 2.5 degrees if it's Okay. If it does not measure approximately 1091 ohms, replace the temperature sensor probe, part number 316217001. If the oven temperature sensor has approximately 1091 ohms then the oven control board will most likely need to be removed and replaced. The sensor probe can be ordered from
