KitchenAid Range Error Code F6-E4

F6-E4 means the range has detected a loss of communication between the display board and the power board. These two boards must exchange signals continuously for the range to operate. The fault is most often traced to the P2 connector that links them, which may have come loose inside the unit.

Unplugging the range for a few minutes may temporarily clear the code, but if the underlying connection issue is not fixed, the F6-E4 error will return once power is restored and the boards attempt to communicate again. A reset alone is not a repair.

If only the connector needs reseating, there may be no parts cost, though a service call typically runs between $75 and $150. If the wiring harness needs replacement, expect parts and labor to fall in the $100 to $250 range. A display board or power board replacement can cost between $200 and $500 or more depending on the specific model and labor rates in your area.

In many cases, yes. Start by unplugging the range and removing the back panels to locate and firmly reseat the P2 connector at both the display board and the power board. If the error returns after reconnecting power, the repair becomes more involved and may require harness or board replacement, which many homeowners prefer to leave to a technician.

No. When F6-E4 is active, the display board and power board are not communicating properly, which means the range cannot reliably control its heating elements or other functions. You should avoid using the range until the fault is diagnosed and resolved.
