Error codePO
ApplianceRefrigerator
Quick answer
PO means the refrigerator lost power and the freezer reached 18F (-8C) or more. Pressing MEASURED FILL acknowledges the alert.
Model compatibility: KitchenAid reuses codes across series and model years, so PO may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
A power outage indicator: the power was off and the freezer reached 18F (-8C) or higher.
PO is an alert
PO stands for power outage. It works as a notice instead of a fault code: the refrigerator lost power, and while it was out the freezer rose to 18°F (-8°C) or beyond.
Signs on the refrigerator
PO is shown where the temperature normally appears.
Three alert tones play.
The word Confirm flashes on the panel and keeps going until you answer it.
How to dismiss it
Locate the MEASURED FILL button, which sits under the word Confirm.
Press it.
PO clears and the display goes back to the Home screen.
Both KitchenAid help pages, French door bottom freezer and side by side, describe this. Only MEASURED FILL is named as the key that acknowledges the alert.
Purpose of the message
The aim of PO is to tell you the freezer warmed while you were out or asleep. The temperature given is a threshold set by the manufacturer and says nothing about the state of the food. Deciding about frozen and chilled items after an outage falls under general food-safety guidance, not this code.
If something else is on the display
The PO articles give nothing further. A refrigerator showing a different message, for example a blinking F, belongs to other entries.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
