Maytag Refrigerator Error Code PO — Power Outage
What this means
The PO error code on Maytag refrigerators is a Power Outage indicator. It appears on the display after the power supply to the refrigerator has been interrupted and the freezer temperature has risen to 18°F (-8°C) or higher. An alert tone will sound three times. This is not a malfunction — it's an informational code to help you decide whether food may have spoiled.

Step-by-step fix
3 stepsAcknowledge the alert
Press the 'Alarm Reset' button, or any button on the control panel to silence the alert and clear the PO code from the display.
On some models, you may need to hold the button for 3 seconds.
Check food safety
If the outage lasted more than 4 hours with the doors closed, check the temperature inside with a thermometer. Frozen food that has thawed above 40°F should not be refrozen. Refrigerated food above 40°F for more than 2 hours should be discarded.
A full freezer holds temperature for about 48 hours; a half-full freezer about 24 hours.
Monitor temperature recovery
After clearing the code, allow 24 hours for the refrigerator and freezer to return to normal operating temperatures. Avoid opening the doors frequently during this period.
Set the refrigerator to its coldest setting temporarily to speed recovery, then adjust back to normal after 24 hours.
When to call a professional
No professional service needed for a PO code. If the refrigerator doesn't cool properly after power is restored and 24 hours have passed, there may be a compressor or control issue.
