Customer Questions and Answers for Oven Sensor Assembly by Whirlpool

Hello Laura! Yes, the F3 E2 failure code indicates a failed oven temperature sensor. You will need to replace part number WPW10181986. Here are some instructions I've located on how to replace an oven sensor, hope they help! Remove screws from inside the oven ( some newer models like Frigidaire/Kenmore have the 2 screws on the outside at the back ) and pull towards you the inoperative sensor. If the connection on the sensor or the wire harness is not applicable to your model, use two ceramic high temp wire connectors to splice the wires together. Strip insulation on each wire approximately 1/2" from the end. On some models, the sensor may be serviced from the front, on others the hole in the oven liner is not large enough for the wire nut/connector to pass through and must be serviced from the rear. Important: Make sure the wire nuts/connectors are completely through the insulation and not touching the back of the oven cavity. Once the wire nuts/connectors are properly positioned, reinstall the sensor screws removed earlier.
