Whirlpool Refrigerator PO Alert: Power Outage Warning

Quick Answer

Whirlpool refrigerator PO is an informational alert, not a fault code. It means the refrigerator detected a power interruption: an outage, a tripped breaker, or the unit being unplugged. The refrigerator is fully operational and working normally.

The refrigerator is fully operational and working normally when PO appears. Press any button on the control panel to acknowledge and clear the message. The real concern is food safety: if the outage lasted more than 4 hours and the refrigerator section climbed above 40F, use USDA guidelines to evaluate whether perishables are still safe. Check the freezer section separately - a full freezer holds safe temperatures for roughly 48 hours, a half-full freezer for 24 hours.

Frequently Asked Questions

Is PO a serious error on a Whirlpool refrigerator?

No. PO is purely informational. It means the refrigerator noticed a power interruption and is alerting you to check food safety. The refrigerator hardware is working correctly. Press any button to clear the alert.

How do I clear PO on my Whirlpool refrigerator?

Press any button on the control panel to acknowledge and clear the PO message. If the display does not respond, try pressing Start or OK. The message should disappear immediately.

My Whirlpool refrigerator keeps showing PO but there was no power outage. What is wrong?

Repeated PO alerts without a real outage can indicate a loose power cord connection, a failing outlet, or a momentary voltage drop in your home electrical system. Check that the cord is firmly plugged in and test the outlet with another appliance.

How long can a Whirlpool refrigerator stay cold during a power outage?

A full refrigerator stays at safe temperatures for about 4 hours during an outage if the doors remain closed. A full freezer holds temperature for 24-48 hours. Keep doors closed as much as possible to maximize cold retention.

Does PO mean my refrigerator lost power for a long time?

PO does not record the duration of the outage, only that one occurred. You cannot determine outage length from the PO alert alone. Check your local utility records or note the time you last saw the refrigerator operating normally to estimate outage duration.
