Whirlpool Refrigerator PO error code

PO means the refrigerator detected a power outage. It is not a fault — just a notification that power was lost, so you know to check your food.

Also shown as: PO, Po

Last updated: October 6, 2026

Quick answer: Whirlpool refrigerator error code PO: power outage notification. The most common cause is house power outage. Try this first — clear the PO display. If that does not clear it, check your food. If the code persists, call a qualified technician.

What causes the PO error?

  • House power outage
  • Tripped breaker or blown fuse
  • Refrigerator accidentally unplugged
  • Loose wall outlet

How to fix Whirlpool PO — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Clear the PO display
    Press any button on the control panel to clear the PO message. The refrigerator will resume normal operation.
  2. Check your food
    If the outage was long, check food safety: perishables above 40°F (4°C) for more than 2 hours should be thrown out. When in doubt, throw it out.
    Safety warning: Never taste food to check if it is safe. If a perishable was warm for over 2 hours, discard it.
  3. Verify the power source
    Make sure the refrigerator plug is fully seated and the breaker is on. If the outlet is loose or the breaker tripped for no clear reason, get it checked.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • PO appears repeatedly with no known outage
  • The breaker trips for no clear reason
  • The outlet or cord is loose, hot, or damaged
  • The refrigerator will not restart after power returns

Frequently asked questions

Is PO an error I need to fix?

No. PO is purely informational — it tells you the power went out. Clear it and carry on.

PO keeps appearing with no outage. Why?

A loose outlet, a failing breaker, or a worn power cord can drop power for a split second. Check the plug and outlet.

How long was the power out?

The fridge cannot tell you. Check a clock that blinks, or put a cup of frozen water with a coin on top in the freezer — if the coin sank, food thawed.
