KitchenAid Range Error Code F3E0

F3E0 means the control board detected an open circuit in the oven temperature sensor. The board receives no usable resistance signal from the sensor, so it cannot monitor oven temperature and shuts down the bake and broil functions. The fault is most often caused by a failed oven sensor or a break in the wiring harness connected to it.

The oven will not operate while F3E0 is active because the control board has no temperature data to regulate the heating elements safely. Surface burners on a gas or electric range are typically unaffected by this fault code, so cooktop cooking is generally still possible. Do not attempt to bypass or ignore the fault and force oven operation, as uncontrolled heating element operation is a fire and safety risk.

Unplug the range, then remove the two screws holding the sensor to the oven back wall and pull it forward enough to disconnect the wiring harness. Set a multimeter to measure resistance (ohms) and probe the two terminals on the sensor connector. At room temperature, a functional oven sensor reads roughly 1080 ohms. A reading of infinite resistance or OL confirms the sensor has an open circuit and needs replacement. If the sensor reads correctly, the fault is in the harness or control board.

Start by unplugging the range and locating the oven sensor at the upper rear wall of the oven cavity. Disconnect the sensor and test its resistance with a multimeter; a good sensor reads approximately 1080 to 1090 ohms at room temperature. If the reading is infinite or OL, replace the sensor. If the sensor tests correctly, inspect the harness and connectors between the sensor and the control board for breaks or corrosion before considering a control board replacement.

An oven temperature sensor for a KitchenAid range typically costs between $20 and $60 for the part. If you are comfortable with basic appliance repair, replacing it yourself takes about 15 to 30 minutes and requires only a screwdriver. A professional service call will add $100 to $200 in labor depending on your area. If the control board is the actual cause, board replacement costs $150 to $350 or more for the part alone, making professional diagnosis worthwhile before committing to that repair.
