How to Reset a Whirlpool Refrigerator

Confirm PO notices on the display; other codes reset via a 60-second power-cycle.

Reset Steps

1
For PO: press the indicated button (often 'Measured Fill' or 'Confirm') to acknowledge.
2
For fault codes: unplug or breaker-off for 60 seconds, restore power.
3
Allow 2–4 hours of run time before judging whether a cooling-path fault has returned.

💡 Good to know: SY EF that returns after a defrost thaw means the fan motor itself is failing — it is accessible behind the freezer back panel.

If the Code Comes Back

A code that returns after a reset means the underlying fault is still present. Look up your exact code for its causes and step-by-step fix:

SY EF Evaporator fan motor failure SY CF Condenser fan motor failure E0 Freezer thermistor failure PO Power outage indicator — power was interrupted CF Communication failure between control boards 18 C Ice maker fault — ice maker not cycling correctly

Frequently Asked Questions

What does PO mean on my Whirlpool fridge and how do I clear it? +

PO is a power-outage notification, not a fault. Press the confirm button shown on the dispenser display to clear it, and assess whether food stayed cold.
