KitchenAid Range Error Code F3

F3 on a KitchenAid range indicates that the electronic control module has detected a shorted oven temperature sensor circuit. The control sounds an alarm and disables all cook modes as a safety precaution. The fault points to either the temperature sensor probe itself, the wiring harness, or the connector at the control board. Diagnosis starts by checking all harness connections before replacing the sensor.

No, you should not attempt to use the oven while F3 is active. The control has intentionally inhibited all cook modes because it cannot accurately monitor oven temperature, which creates a risk of uncontrolled heating. The range should remain out of service until the sensor issue is diagnosed and repaired.

If the fix is simply reseating a loose connector, there is no parts cost involved. Replacing the oven temperature sensor is generally an affordable repair, with sensor parts typically ranging from $20 to $75 depending on the model. If a technician is performing the repair, expect total costs including labor to fall in the range of $100 to $250. Control board replacement, if ultimately required, is more expensive and typically ranges from $200 to $400 or more.

Many technicians and experienced DIYers can resolve an F3 code by first reseating the harness connector at the oven temperature sensor and the 8-pin connector at the control module, since a loose connection is sometimes the entire cause. If that does not clear the fault, replacing the oven temperature sensor is a straightforward repair that typically involves removing a couple of screws inside the oven cavity and unplugging the old sensor. Always disconnect power to the range before working on any components.

Disconnecting power to the range for a few minutes may temporarily clear the F3 display, but the fault will return as soon as the control re-evaluates the sensor circuit if the underlying problem has not been fixed. A reset is useful for confirming whether the fault is intermittent, but it does not substitute for inspecting and correcting the shorted sensor or wiring.
