What the Error Code Means
Error code PO generally means the refrigerator detected a recent power interruption and is reporting it to you.
It points to a power event rather than a confirmed failure.
Common Symptoms You May Notice
- The display shows PO and the unit may beep.
- Temperatures may have risen briefly after the outage.
- The refrigerator returns to normal cooling after reset.
Most Common Causes (From Least to Most Serious)
- Recent power outage or unplugging: If power was interrupted, the refrigerator records the event and alerts you.
- Loose power connection: A plug that is not fully seated can cause brief interruptions.
- Momentary voltage drop: In some cases a short electrical dip can trigger the alert.
Safe Things You Can Check Yourself
- Press any key or reset the alert to clear the PO display.
- Confirm the power cord is fully seated in the outlet.
- Monitor temperatures for a few hours to ensure cooling is stable.
If at any point this feels unsafe or unclear, stop and contact a professional.
When to Stop and Call for Service
- The PO code returns repeatedly without a known outage.
- The refrigerator does not return to normal cooling.
- You notice burning smells, sparking, or repeated shutdowns.
Typical Repair Cost Range
$0-$200 is typical for diagnosis if power-related issues persist, depending on the cause and parts involved.
Costs vary by region, model, and provider. Request an estimate before approving any repair.
