KitchenAid Refrigerator PO Error: Power Outage Warning
What Does KitchenAid Refrigerator Error Code PO Mean? PO on a KitchenAid refrigerator means a Power Outage was detected. The main control board monitors incoming voltage, and when supply power drops below operating threshold — even briefly — it logs the event and displays PO as soon as electricity returns. Unlike a mechanical fault code, […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Yes. PO is an informational notification identical in nature to PF. The refrigerator is safe to use once the alert is cleared and compartments return to set temperatures.
Can I reset the code?
Yes. Any button press on the control panel clears PO. If the code recurs regularly without real outages, the power supply path or the board itself should be inspected.
When to stop immediately?
Stop if you notice: PO repeats multiple times per week with no known outages, Compartment temperatures do not recover within two hours of clearing.
Symptoms You May Notice
PO appears on display after electricity is restored
The panel shows PO with an audible beep sequence immediately upon power restoration, indicating the board registered an outage interval.
Freezer temperature reads higher than set point
Because compressor operation stopped during the outage, freezer temperature may have climbed above the target 0°F set point, potentially softening ice cream or surface-thawing foods.
Dispenser or ice maker inoperative after power returns
Water dispenser and ice maker functions may be held in standby until the PO alert is acknowledged and temperatures stabilize.
Possible Causes
Utility power interruption of any duration
Even a momentary voltage dip of sufficient magnitude causes the control board to record PO and notify the user on the next power-up.
DIY PossibleExtension cord or power strip voltage drop
Running a refrigerator on an undersized extension cord can cause a voltage drop severe enough for the board to interpret as an outage.
DIY PossibleInternal control board capacitor degradation
Aged capacitors on the main board may fail to bridge short voltage dips, causing the board to interpret minor fluctuations as full outage events.
Requires ProfessionalSafe Checks You Can Do
-
1
Clear the PO alert by pressing any control button
Touch any pad on the dispenser or fresh food control panel to acknowledge the PO notification. The display returns to normal temperature readout and the refrigerator resumes full operation.
Do not confuse PO with other codes — it is always a power-event notification and does not indicate a component failure by itself.

2
Check that the refrigerator is plugged directly into a wall outlet
Confirm the power cord connects directly to a dedicated 15- or 20-amp grounded outlet rather than a power strip or extension cord. Insufficient ampacity causes voltage sags that trigger repeated PO events.
KitchenAid refrigerators require a dedicated circuit. Sharing with other high-draw appliances leads to nuisance PO codes over time.
When to Call a Professional
Contact a qualified technician if:
- Outlet voltage unstable or below 108 V under load
- PO logs combined with component failure codes
- Control board shows signs of capacitor bulge or burn marks
