KitchenAid refrigerators are manufactured by Whirlpool and share the same error code system. PO (Power Outage) is the most displayed code - it appears after any power interruption and simply requires pressing any button to dismiss. It is NOT an error - just a notification. KitchenAid does not use traditional alphanumeric error codes like Samsung or LG. Instead, most faults are indicated by temperature warnings or by the ice maker shutting down. KitchenAid built-in models (KBSD series) and French door models (KRFC series) share Whirlpool diagnostic procedures. Enter diagnostic mode: press the door switch 3 times within 10 seconds, then release. Some models: open and close the door 3 times within 10 seconds.
