PO is short for Power Outage. It tells you the refrigerator lost its supply of electricity, so frozen food may have thawed. The listings cover bottom-freezer and side-by-side refrigerators.
When it appears
The indicator shows after an interruption during which the freezer warmed to 18°F (-8°C) or above.
What the owner sees
PO takes the place of the temperature on the display.
Three alert tones sound.
The word Confirm blinks until the outage is acknowledged.
Questions after a power outage, or a refrigerator that behaves oddly afterward? Call (415) 687-4102 for Whirlpool refrigerator service in San Francisco and nearby cities. Whirlpool refrigerator repair explains the visit; keep the model number and a note of the PO display handy.
Model compatibility: 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.
