Answer to continue safely
Is it safe to keep using?
Maybe. The freezer is operational, but verify food safety before consuming stored items. If temperatures stayed below 32°F, food with ice crystals is generally safe to refreeze.
Can I reset the code?
Yes. Press and hold the Alarm Reset or Power button for 3 seconds to clear the PO code once power is stable and the temperature is recovering.
When to stop immediately?
Stop if you notice: Stop using the freezer for food storage if the internal temperature has exceeded 40°F for more than 2 hours — discard perishables and contact a technician., Discontinue use if the PO code reappears within minutes of being reset with no actual outage, as this points to a control board fault..
Symptoms You May Notice
Alarm sounds after power returns
The freezer emits an audible alert and displays PO on the control panel when power is restored following an outage.
Temperature display shows elevated reading
The internal temperature may read higher than the set point, indicating the freezer warmed up during the power loss.
Compressor runs continuously
After power returns the compressor works hard to pull the cabinet back down to the set temperature, resulting in constant run cycles.
Door alarm may activate simultaneously
If the temperature rose significantly, the high-temp door alarm may also sound alongside the PO notification.
Possible Causes
Utility or household power outage
A grid interruption or tripped breaker removed power from the freezer for an indeterminate period.
DIY PossibleLoose power cord or outlet fault
A partially inserted plug or failing outlet caused an intermittent power loss that the board recorded as an outage.
DIY PossibleControl board voltage sensitivity
Rarely, the control board triggers PO from minor voltage fluctuations rather than a true outage, indicating a board issue.
Requires ProfessionalSafe Checks You Can Do
-
1
Check the circuit breaker
Go to your electrical panel and confirm the breaker for the freezer circuit is fully in the ON position. Reset it if it has tripped.
A breaker that trips repeatedly suggests an overloaded circuit — consider moving the freezer to a dedicated outlet.
-
2
Inspect the power cord and outlet
Unplug the freezer, check the cord for damage, and plug it back in firmly. Test the outlet with another device to confirm it is live.
Avoid using extension cords with freezers — they can cause voltage drops that mimic outages.
-
3
Reset the PO alert
Press and hold the Alarm Reset button (or the Power button on some models) for 3 seconds until the PO code clears from the display.
Refer to your model's user guide for the exact reset key combination if the standard method does not work.
When to Call a Professional
Contact a qualified technician if:
- PO code returns repeatedly without any power interruption, suggesting a control board or wiring fault.
- The freezer fails to cool back down to the set temperature after power is restored, indicating a possible compressor or refrigerant issue.
