How to Enter Diagnostic Mode on a Whirlpool Refrigerator

Whirlpool refrigerators with dispensers show codes (PO, CF, SY EF…) on the dispenser display; service diagnostics are entered from the dispenser buttons.

Step-by-Step: Whirlpool Refrigerator Diagnostics

1
Read the code from the dispenser display. PO = power outage notice (informational); SY EF = evaporator fan fault (cooling at risk).
2
Service mode on most dispenser models: the entry combination is model-specific (commonly holding two dispenser buttons together for several seconds) — the tech sheet behind the lower front grille documents it.
3
For SY EF: open the freezer, remove the back panel, and check whether the evaporator fan is iced or jammed — icing from a failed defrost cycle is the leading cause.
4
For no-code cooling loss: check the condenser coils (under/behind) and the condenser fan before anything else.

💡 Good to know: PO clears by pressing the confirm button shown on the display — it just tells you power was lost. Food-safety judgment matters more than the code.

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.
