ERROR CODES
3/9/20262 min read
If your refrigerator display suddenly shows Whirlpool refrigerator error code PO, it usually means the appliance has experienced a power outage or power interruption.
The PO code stands for “Power Outage.” It appears when the refrigerator loses electrical power and then turns back on.
This message is not always a sign of a serious problem. In many cases, it simply indicates that the refrigerator temporarily lost power.
What Does Whirlpool Refrigerator Error Code PO Mean?
The PO error code on a Whirlpool refrigerator indicates that the appliance has detected a recent power loss.
When the refrigerator regains power, the control system displays the PO code to alert you that the internal temperature may have risen while the power was off.
This feature helps protect food safety by informing you that the refrigerator was not cooling during the outage.
Common Causes of Whirlpool Refrigerator Error Code PO
Several situations can trigger this message.
1. Power Outage
The most common reason is a temporary power outage in your home or neighborhood.
When power returns, the refrigerator displays the PO code to notify you.
2. Refrigerator Unplugged
If the refrigerator was unplugged for cleaning or maintenance, the control panel may show the PO message once power is restored.
3. Circuit Breaker Tripped
A tripped breaker or blown fuse can briefly cut power to the refrigerator.
When electricity returns, the PO error appears.
4. Loose Power Cord
If the refrigerator power cord becomes loose in the outlet, it may cause intermittent power loss.
5. Electrical Fluctuations
Voltage fluctuations or short power interruptions can also trigger the PO code.
How to Fix Whirlpool Refrigerator Error Code PO
Follow these simple steps to clear the message.
Step 1: Reset the Display
Most Whirlpool refrigerators allow you to clear the PO message by pressing the “Alarm Reset” or “Power Outage” button on the control panel.
Once pressed, the display should return to normal.
Step 2: Check the Power Supply
Make sure the refrigerator is receiving stable power.
Check for:
A properly plugged-in power cord
A working electrical outlet
A reset circuit breaker
Step 3: Inspect Food Temperature
If the power outage lasted a long time, check the temperature inside the refrigerator and freezer.
Food may spoil if the temperature rises above safe levels for several hours.
Step 4: Allow the Refrigerator to Cool
After power returns, the refrigerator may need several hours to reach the proper cooling temperature again.
Avoid opening the door frequently during this period.
Step 5: Monitor for Recurring Power Loss
If the PO code appears repeatedly without a known power outage, there may be an issue with:
The electrical outlet
The power cord
The refrigerator’s internal power system
Signs There May Be an Electrical Issue
You may notice these symptoms along with the PO code:
Refrigerator turning off and on unexpectedly
Interior lights flickering
Cooling stopping temporarily
Error appearing frequently
These signs may indicate unstable power supply.
When to Call a Technician
Consider professional repair if:
The PO code appears repeatedly
The refrigerator loses power frequently
Cooling problems continue after power is restored
Electrical components appear damaged
A technician can inspect the refrigerator’s power system and control board.
The Whirlpool refrigerator error code PO simply indicates that the appliance experienced a recent power outage. In most cases, clearing the message and allowing the refrigerator to cool down resolves the issue.
