KitchenAid Range Error Code F3E6

F3E6 indicates that the warming drawer temperature sensor circuit is open, meaning the control board is not receiving any signal from the warming drawer's temperature sensor. This prevents the control board from regulating the warming drawer's heating element safely. The fault can be caused by a loose connector, a failed sensor, or a break in the wiring harness.

The F3E6 fault specifically disables the warming drawer function, so the warming drawer should not be used while the code is present. The main oven and cooktop burners are separate systems and are generally not affected by this fault. That said, it is best practice to address the error promptly rather than leaving a sensor fault unresolved.

If the fix is simply reseating a loose connector, there is no parts cost and only your time is involved. A replacement warming drawer temperature sensor typically costs between $20 and $60 for the part. If professional labor is needed, total repair costs including diagnosis and labor generally range from $100 to $250 depending on your location and the extent of the repair required.

Many cases of F3E6 are resolved simply by unplugging the range, removing the back panels, and firmly reseating the warming drawer sensor connector. If that does not clear the code, a technician or experienced DIYer can test the sensor with a multimeter and replace it if it shows an open circuit. Wiring harness repairs or control board replacement are more advanced and may warrant professional service.

Unplugging the range for a few minutes and restoring power may temporarily clear the code, but it will return if the underlying problem has not been fixed. A reset does not repair a failed sensor, broken wire, or disconnected connector. The fault code will reappear as soon as the control board checks the sensor circuit again.
