KitchenAid Oven Error Code F6 E5

The F6 E5 error code on a KitchenAid oven indicates that the electronic control board has not been programmed with a cavity size parameter. This is a configuration-level fault rather than a component failure. The control relies on a stored cavity size value to calibrate cooking functions, temperature regulation, and timing algorithms correctly. When this value is absent or has been cleared, the control cannot operate within its normal parameters and flags the F6 E5 code to alert the technician or user that setup is incomplete.

This condition most commonly occurs after a control board has been replaced and the replacement unit was not fully configured before being put into service. It can also occur if the board's non-volatile memory was corrupted or reset, which can happen following a power surge, a hard reset, or in rare cases a firmware issue. Because the cavity size setting is stored in the control's memory rather than in a separate component, the fix is almost always a programming procedure rather than a parts replacement.

When F6 E5 appears, the control is designed to immediately enter cavity size selection mode. Using key 6 to scroll down and key 3 to scroll up, the correct cavity size can be selected from the available options. Pressing START accepts and saves the selection to the control's memory. Once the cavity size is properly stored, the error clears and normal operation resumes. If the error returns after this procedure, it may indicate that the control board is unable to retain settings, pointing to a faulty board that requires replacement.
