KitchenAid Refrigerator PO — What It Means & How to Fix It

Also shown as PO Error Code on some models.

By Callum Griffin · Researched and verified against manufacturer and repair documentation · Reviewed September 2026

PO appears after a power outage — the freezer warmed to about 18°F (-8°C) or higher, and the fridge is asking you to confirm the food is safe.

What this code means

After a power interruption long enough to warm the freezer, the refrigerator shows PO with a blinking CONFIRM prompt — your cue to check the food and acknowledge the alert.

PO appears on KitchenAid French-door and select side-by-side refrigerators with the Whirlpool-family electronics platform. The clear key (here MEASURED FILL under CONFIRM) can be labeled differently on other models — your manual is the reference.

Most likely causes

Power outage long enough to warm the freezer to about 18°F or higher Very common Check food, press Confirm
A brief outage or flicker that still triggered the alert Occasional Press Confirm to clear

What you can try yourself

  1. Check the frozen food: if items show signs of thawing, discard anything that reached an unsafe temperature.
  2. When you are satisfied the food is still cold and solidly frozen, press MEASURED FILL — the key under the blinking CONFIRM — to clear the alert.
  3. The three-tone alert stops once you confirm, and the display returns to normal.
  4. If food was compromised, let the unit run until it is cold again before restocking.

Frequently asked questions

What does PO stand for?

Power outage. It is the refrigerator's way of telling you power was off long enough to warm the freezer into the alert range.

Why do I have to press a key to clear it?

The fridge wants a human to confirm the food was checked — that is the point of the blinking CONFIRM prompt. Pressing the key tells it everything is fine.

About how long does the power need to be out to trigger PO?

It varies with the unit and start temperature, but the alert fires when the freezer reaches about 18°F (-8°C) — treat that as the signal to check the food.
