MAYTAG PO

Maytag Refrigerator Error PO: Power Outage Indicator

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The refrigerator is displaying PO to indicate that a power outage occurred while it was unattended. The display is alerting the owner to check food safety — the temperature may have risen during the outage. This is an informational indicator, not a mechanical fault.

Severity

Low - usually safe to check with basic user-accessible cleaning or inspection on the Maytag refrigerator.

Can you fix it yourself?

Yes — DIY-safe

Most likely cause

Power outage or brownout caused the refrigerator to shut off

Estimated time for safe first checks: 1–2 min to clear; allow 24 hours for temperatures to stabilize.

Step-by-Step DIY Fix Guide

  1. SAFETY: No electrical hazard — PO is an informational display code.
  2. Press OK, Alarm Reset, or any button on the display (varies by model) to acknowledge and clear the PO notification.
  3. Check the internal temperature display — if the refrigerator is back to set temperature (typically 37°F fresh food, 0°F freezer), food safety was maintained.
  4. Check the condition of freezer foods: items with ice crystals still present can be safely refrozen. Items that have fully thawed should be discarded or cooked immediately.
  5. Allow 24 hours after restoring power for both compartments to return to stable set temperatures.

If the warning comes back after restart

  • If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
  • PO appears but the refrigerator was not unplugged and no outage occurred — the control board may have a power supply fault

What This Error Means

Error PO on your Maytag refrigerator means: The refrigerator is displaying PO to indicate that a power outage occurred while it was unattended. The display is alerting the owner to check food safety — the temperature may have risen during the outage. This is an informational indicator, not a mechanical fault. The refrigerator's self-diagnostic system has detected this condition and generated this alert.

The most frequent cause is power outage or brownout caused the refrigerator to shut off. Work through the causes and fix steps below in order.

Error PO is DIY-safe. No special tools are required. Follow all steps in sequence.

PO is purely informational — the refrigerator is operating correctly and alerting the owner that an outage occurred while it was unattended. The primary concern after any power outage is food safety: the USDA recommends discarding perishable foods that have been above 40°F for more than 2 hours.

Most Likely Cause by Symptom

The Maytag refrigerator may stop, pause, or refuse to complete the cycle normally.

Likely cause: Power outage or brownout caused the refrigerator to shut off

Check first: SAFETY: No electrical hazard — PO is an informational display code.

Common Causes

  • Power outage or brownout caused the refrigerator to shut off
  • Circuit breaker tripped for the refrigerator circuit
  • Refrigerator accidentally unplugged

What Not to Do

  • Do not ignore PO without checking food temperatures — a long outage can spoil perishables even if the refrigerator is now running normally

Model and Display Variation Notes

Model-family notes

  • Maytag refrigerator display wording and code formats can vary by series.
  • If your model behaves differently, check the owner manual before trying any deeper maintenance step.

Display and panel differences

  • Panel wording can vary by series, so confirm the exact code pattern before buying parts.

Parts, Tools and Service Options

Manual and model check

Check your exact model and manual before ordering any Maytag refrigerator parts.

This section stays model-first because exact manual and parts matching matters more than a generic replacement suggestion here.

When Not to Keep Troubleshooting

PO appears but the refrigerator was not unplugged and no outage occurred — the control board may have a power supply fault

How to Prevent It Recurring

  • Consider plugging the refrigerator into a UPS (uninterruptible power supply) or surge protector — a UPS provides short-term backup power through brief outages and prevents repeated PO notifications
