Verifying that you are not a robot.. Is your Whirlpool fridge showing a PO or P0 error? Discover easy steps to troubleshoot and resolve this power outage issue quickly and safely.. Step 1: Reset the Refrigerator. Sometimes, a quick reset is all your fridge needs. Think of it like restarting your computer when it acts up. Here's how to do it:
After a power outage, your Whirlpool fridge displays the PO code to alert you that the internal temperature might have been compromised during the outage. Power Surges: Sudden power surges can cause the refrigerator to lose power momentarily.. The control panel temperature display will read "PO," and an alert tone will sound three times. "Confirm" will blink until you acknowledge the power outage by pressing MEASURED FILL under "Confirm." Once the power outage has been confirmed, the "PO" will disappear, and the display will return to the Home screen.
