Answer to continue safely

Is it safe to keep using?

Yes. The PO code is informational only. The appliance itself is operational — focus on checking whether stored food is still safe to consume.

Can I reset the code?

Yes. Press any button on the control panel to clear the PO code. If it reappears without a power event, contact a technician.

When to stop immediately?

Stop if you notice: The PO code reappears repeatedly without any known power interruption., Perishable food has been stored at unsafe temperatures for more than two hours — discard affected items immediately..

Symptoms You May Notice

Interior warm after power restored

The fridge compartment feels noticeably warmer than the set temperature when power comes back on after an outage.

Ice bin contents melted

Ice that was stored in the bin has partially or fully melted during the period without power.

Food safety in question

Perishables stored in the fridge may have been above 40 °F long enough to require inspection before consumption.

PO flashing on display panel

The control display flashes "PO" immediately after power is restored to alert you that an outage was logged.

Possible Causes

1

Power interruption or outage

The most common cause. Any loss of mains power — even momentary — triggers the PO alert on WUR and WHR compact models when supply is restored.

Requires Professional
2

Loose or partially seated power cord

If the plug is not fully inserted into the wall outlet, micro-interruptions can repeatedly trigger the PO code without an actual outage.

Requires Professional
3

Faulty control board misreading voltage

Rarely, a defective main control board may log a false power-loss event. This requires professional diagnosis and board replacement.

Requires Professional

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Acknowledge and clear the code

    Press any control-panel button to dismiss the PO alert. Confirm the display returns to the normal temperature read-out.

    If the code clears and does not return, no further action is needed beyond a food-safety inspection.

    Tools required
  2. 2

    Check the power cord and outlet

    Unplug the fridge, inspect the cord for damage, and firmly re-seat the plug. Plug a small lamp into the same outlet to confirm it is live.

    Avoid using extension cords or power strips with compact fridges — they can cause voltage drops that mimic power outages.

    Tools required
  3. 3

    Verify internal temperature recovery

    Place a thermometer inside the compartment and check that it reaches your set point within two hours of the unit running.

    A compact fridge should recover to safe temperature (below 40 °F / 4 °C) within 60–90 minutes under normal conditions.

    Tools required

When to Call a Professional

Contact a qualified technician if:

  • The PO alert returns after every power cycle despite the outlet being confirmed stable.
  • Control panel buttons fail to clear the code after multiple attempts.
