KitchenAid Refrigerator PO — Power Outage Alert
KitchenAid Refrigerator · Error code PO
What PO Means
The refrigerator detected a power interruption and is alerting you that interior temperatures may have risen above safe levels during the outage. The display flashes PO until acknowledged.
Symptoms
- PO flashing on display
- Audible alert beeping
- Temperature display may show elevated reading
- Food may feel warm or partially thawed
Common Causes
Utility power loss, tripped breaker, or unplugged cord exceeded the unit's safe-temp window.
Plug not fully seated in outlet or damaged cord creating intermittent power.
Kitchen circuit breaker tripped due to overload or fault.
Rare — board falsely detects power loss events.
How to Fix It
- Press and hold the Measured Fill or alarm-reset pad for 3 seconds to clear PO.
- Check that the unit is plugged in firmly and the breaker is on.
- Verify freezer contents — if ice cream is soft or meat above 40°F, discard per USDA guidance.
- Allow 24 hours for temperatures to fully stabilize before judging cooling performance.
- If PO returns without a known outage, check outlet voltage (should be 108–132 VAC) and inspect the cord.
- If voltage is correct and PO persists, suspect the main control board.
