Error codePO
ApplianceRefrigerator
Quick answer
PO tells you the refrigerator lost power and the freezer rose to 18F (-8C) or higher. Confirming the outage clears it.
Model compatibility: JennAir reuses codes across series and model years, so PO may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
PO reports a power outage during which the freezer temperature rose to 18°F (-8°C) or higher.
PO is a notice
On a JennAir built-in or French door refrigerator, PO stands for power outage. It tells you that the refrigerator lost power and that the freezer warmed up in the meantime, which makes it more of a notification than a breakdown.
When JennAir shows it
There is a number behind the indicator: the power supply was off and the freezer temperature climbed to 18°F (-8°C) or higher. A brief interruption that did not push the freezer that far is not what the message describes.
Signs on the refrigerator
“PO” in the temperature display of the control panel.
Three alert tones.
A blinking “Confirm” on the panel.
How to clear it
Press MEASURED FILL, the control under “Confirm”. This acknowledges the outage.
“PO” goes away and the display returns to the Home screen.
The blinking carries on until you do this. JennAir gives no other step and no power reset.
Limits of the message
How long the outage lasted and what happened to the food are not stated. All the page reports is that 18°F (-8°C) was reached. Decide about the freezer contents with ordinary food-safety judgment. A PO that shows up when no outage occurred is not explained on the page; that is a matter for service.
Common questions
Will the tone repeat? The page says it sounds three times and does not mention repeating.
Do undercounter models show PO? The page covers built-in and French door bottom-freezer refrigerators, not the beverage center or wine cellar.
When PO returns with no real outage behind it, call (310) 622-9465. Explain when it appears and whether you confirmed it each time. Visit the refrigerator repair page for more.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
