KitchenAid Range Error Code F3E2

F3E2 on a KitchenAid range indicates the control board has detected a runaway oven temperature condition, meaning the oven temperature climbed beyond the acceptable threshold and did not respond to normal regulation signals. The control monitors oven temperature through the oven temperature sensor (RTD probe) and uses that data to cycle the bake or broil elements. When the sensor reports temperatures that are excessively high or continue rising without correction, the board flags F3E2 and shuts down the heating circuit as a safety measure. The two primary suspects are a failed oven temperature sensor sending inaccurate high readings, or a faulty control board that is misreading valid sensor input or failing to cut power to the heating elements.

For homeowners, this error means your oven's safety system detected that the oven was getting too hot or was no longer controlling temperature correctly. The oven shuts itself down to prevent damage or a fire hazard. This is not a minor nuisance code. Do not attempt to override it or continue using the oven until the underlying cause is diagnosed and repaired.

The oven sensor is the first component to test because it fails more frequently than the control board and costs significantly less to replace. A sensor with a short or incorrect resistance reading can report false high temperatures to the board, triggering this fault without the oven ever actually overheating.
