Quick answer
A PO reading with three alert tones means the refrigerator lost power and the freezer warmed. Confirm it to return to the Home screen.
Model note: Whirlpool 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.

A plain-language reading of the code — always confirm against your model’s documentation.
Mean
PO is the Power Outage indicator shown after the freezer warmed during a power loss.
Meaning of PO
PO stands for Power Outage. It shows when the refrigerator had no power and the freezer temperature rose to 18°F (-8°C) or higher, so the freezer may have thawed. It is listed for bottom-freezer and side-by-side refrigerators.
What happens on the control panel
The temperature display reads PO.
An alert tone sounds three times.
Confirm keeps blinking until you acknowledge the outage.
Clearing it
Press MEASURED FILL under Confirm. Once the outage is confirmed, PO goes away and the Home screen comes back.
