Maytag Refrigerator PO Error Code

Maytag says PO appears when the refrigerator power supply has been off and the freezer temperature has risen to 18°F (-8°C) or higher.

Applies to Maytag full-size side-by-side refrigerator

What the appliance detected

Detected condition

The freezer temperature rose after refrigerator power was interrupted.

What may contribute

Possible causes

  • A household outage or interrupted refrigerator power.
  • Freezer temperature rising during the interruption.
  • Food may need a food-safety check.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the display and model

    • Photograph or write down the exact alert, word, or code before clearing it.
    • Confirm the full model number and Maytag owner manual because controls vary by refrigerator family.

  2. Use only documented external checks

    • Acknowledge the PO alert using the control action documented for the model.
    • Keep doors closed as much as practical while temperatures recover.
    • Check frozen food for signs of thawing before relying on it.

  3. Stop before internal work

    • If the alert remains after documented checks, request service.
    • Do not open sealed-system, compressor, fan, sensor, wiring, or control areas.

Actions not recommended

  • Do not perform refrigerant or sealed-system work.
  • Do not test live voltage or open internal electrical areas.
  • Do not replace compressor, fan, sensor, water-valve, or control parts based only on the display.

When to stop and request service

  • PO returns without a known power interruption.
  • The refrigerator does not cool normally after power is restored.
  • Food safety is uncertain or temperatures remain unsafe.
