Answer to continue safely
Is it safe to keep using?
Yes. After clearing the PO code and cycling the tray, the ice maker is safe to use. Discard any malformed ice from the bin before resuming normal use.
Can I reset the code?
Yes. Press the Alarm Reset button or power cycle the unit to clear the PO code. The ice maker will resume normal operation immediately after the reset.
When to stop immediately?
Stop if you notice: Stop using the ice maker if PO appears multiple times per week without a known household power interruption — this pattern suggests a control board or outlet fault., Discontinue use if the unit fails to produce any ice within 4 hours of the PO code being cleared, as an underlying mechanical issue may have been exposed by the power interruption..
Symptoms You May Notice
Ice tray contains malformed or partial ice cubes
Inspection of the ice mold reveals partially formed, cracked, or irregular ice cubes that resulted from the freeze cycle being interrupted mid-completion.
Ice maker is paused and not cycling after power returns
The unit does not automatically resume ice production after power is restored — it waits for the PO alert to be acknowledged before restarting the cycle.
Audible alert sounds when power is restored
The ice maker emits a series of beeps and displays PO on the panel as soon as power returns, drawing attention to the power interruption event.
Water may be pooled in the ice tray
If the power outage occurred during the fill phase, the tray may contain liquid water that has not yet been frozen, which will freeze into a solid block if left unattended.
Possible Causes
Household power outage or tripped breaker
A utility grid interruption or a tripped circuit breaker removed power from the ice maker during operation, triggering the PO alert upon restoration.
DIY PossibleGFCI outlet trip or loose power connection
A GFCI outlet that has tripped, or a power cord not fully inserted into the outlet, created an interruption that the control board logged as a power outage.
DIY PossibleRecurring false PO from control board voltage sensitivity
A marginally defective control board registers normal voltage fluctuations as outage events and triggers PO repeatedly without any actual power loss.
Requires ProfessionalSafe Checks You Can Do
-
1
Confirm power supply is stable
Check the circuit breaker and verify the outlet is delivering power. If the outlet is GFCI-protected, press its reset button. Plug the ice maker cord in firmly.
Ice makers should be on a dedicated 15A circuit — sharing with a high-draw appliance can cause voltage dips that mimic an outage to the control board.
-
2
Clear the ice tray manually
Press and hold the Test/Harvest button for 3 seconds to initiate a manual cycle. This clears any partial or malformed ice from the tray and fills it with fresh water to start a proper cycle.
If the tray is filled with a solid block of water that froze during the outage, you may need to gently warm the tray exterior with a warm damp cloth to loosen it before cycling.

3
Reset the PO alert and monitor production
Press the Alarm Reset button to clear the PO code, then monitor the ice maker through at least two complete harvest cycles to confirm it is producing properly formed cubes.
A complete ice production cycle takes 90 minutes to 3 hours depending on ambient temperature — allow adequate time before concluding production is normal.
When to Call a Professional
Contact a qualified technician if:
- PO code recurs repeatedly without any verified household power outage, pointing to a faulty control board that needs replacement.
- Ice maker fails to complete a single harvest cycle after PO is cleared and the unit is confirmed to have stable power, suggesting a motor or module failure.
