Kenmore Range Error Code F23

F23 means the Electronic Oven Control has detected a failure in the communication link between itself and the Variable Speed Convection Board. This board manages the convection fan motor speed during cooking. The error is triggered when the signal between the two boards is lost or corrupted. It is most commonly caused by a loose wiring connection between the two boards.

Using the range with an active F23 error is not recommended, particularly for convection cooking functions. The convection fan speed may not be controlled properly, leading to uneven cooking results or potential overheating of the convection system. Standard bake or broil functions that do not rely on the convection board may still operate, but it is best to resolve the error before continued use.

Repair costs vary depending on the cause. If only a connector needs to be reseated, there may be no parts cost, and a service call fee of roughly 75 to 150 dollars could be the primary expense. Replacing the Variable Speed Convection Board typically costs between 100 and 250 dollars for the part alone, plus labor. Replacing the EOC tends to cost more, often in the range of 150 to 350 dollars for the part, making board substitution testing an important step before purchasing components.

A homeowner or experienced DIYer can attempt the first diagnostic step, which involves checking and reseating the connector between P6 on the EOC and P1 on the Variable Speed Convection Board. If the connection is secure and the error persists, further diagnosis or board replacement may be needed. Working inside a range involves high-voltage components, so disconnect power at the breaker before opening the appliance. If you are not comfortable with electrical repairs, a qualified technician should handle it.

Disconnecting power to the range for several minutes will clear the displayed error code, but the F23 will return if the underlying communication fault is still present. A reset is a useful step to confirm whether the fault is intermittent or consistent. If the code returns immediately after restoring power, a physical inspection of the wiring and boards is needed.
