Kenmore Range Error Code F6 E4

F6 E4 means the range has lost communication between the power board and the display board. These two boards need to exchange signals continuously to operate the appliance correctly. The fault is most often caused by a loose P2 connector between the boards, but can also result from wiring damage or a failed board.

Unplugging the range for a few minutes may temporarily clear the code, but if the underlying connection problem is not fixed, F6 E4 will return. A proper repair requires physically inspecting and reseating the P2 connector and confirming the harness and boards are intact.

If the fix is simply reseating the P2 connector, there is no parts cost and only your time is involved. If the wiring harness needs replacement, parts typically run in the range of $20 to $60. A replacement display board or power board generally costs between $100 and $250 for the part alone, with additional labor costs if a technician is needed.

In many cases, yes. The first step is to unplug the range, open the back panels, and firmly reseat the P2 connector at both the power board and display board. If that does not clear the fault, inspect the wiring harness between the boards for damage. Board replacement is more involved but is a manageable repair for someone comfortable with appliance disassembly.

It is not recommended to continue using the range while this code is active. The loss of communication between the power board and display board means the appliance may not respond to controls correctly or consistently. Discontinue use and diagnose the fault before operating the range again.
