KitchenAid Oven Error Code F6 E5

F6 E5 means the control board has not been programmed with a cavity size. This is a configuration fault, not a hardware failure. It most often appears after a control board replacement where the setup step was skipped. The oven will not operate normally until the correct cavity size is selected and saved.

A simple power reset will not clear F6 E5 because the cavity size parameter is still absent after the reset. The error requires the cavity size selection procedure to be completed using the keypad. If the error keeps returning after programming, the control board may be unable to retain the setting and could need replacement.

In most cases, fixing F6 E5 costs nothing because it only requires a programming procedure using the existing keypad. If the control board is faulty and cannot retain the cavity size setting, a replacement control board typically costs between $150 and $400 for the part, with additional labor costs if a technician performs the replacement.

When F6 E5 appears, the control should automatically enter cavity size selection mode. Use key 6 to scroll down through the available sizes and key 3 to scroll up, then press START to accept and save your selection. This programs the setting into the control's memory and should clear the error immediately.

The oven will not function normally while F6 E5 is active because the control lacks the configuration data it needs to manage cooking operations. You should complete the cavity size programming procedure before attempting to use the oven. This is a setup issue and does not indicate a dangerous condition, but normal cooking functions will be unavailable until it is resolved.
