Answer to continue safely
Is it safe to keep using?
Maybe. If the HI alarm appeared after a door opening, power outage, or large food load, continue monitoring and allow 2–4 hours for temperature recovery. If the freezer does not return to setpoint within 4 hours or another fault code is active, stop use and move frozen food to an alternate freezer.
Can I reset the code?
Yes. Pressing any button will silence the HI audible alarm. The code itself clears automatically when the compartment temperature returns to within the normal range. If the freezer cannot reach setpoint, the HI code will persist until the underlying cooling fault is resolved.
When to stop immediately?
Stop if you notice: Compartment temperature does not recover to below 15°F (-9°C) within 4 hours, HI appears alongside F2, DEF, FAN, or FF codes.
Symptoms You May Notice
HI code and audible alarm
The control panel shows HI and an audible beep sounds, indicating the freezer compartment temperature has risen above the controller's alarm threshold.
Frozen food partially thawed
Items near the front or top of the freezer compartment show signs of softening as the compartment temperature rises.
Compressor running continuously
The compressor runs without cycling off as it attempts to recover the compartment temperature, but cannot reach setpoint.
Possible Causes
Door left open or seal failure
The freezer door was open for an extended period or the door gasket is allowing warm air infiltration, raising the compartment temperature.
DIY PossibleLarge warm food load
A large quantity of warm or room-temperature food was placed in the freezer at once, temporarily raising the compartment temperature above the alarm threshold.
DIY PossiblePower outage recovery
The freezer is recovering from a power outage and the compartment temperature has not yet returned to setpoint.
DIY PossibleUnderlying cooling fault
A defrost, fan, compressor, or sensor fault is preventing the freezer from maintaining the setpoint temperature.
Requires ProfessionalSafe Checks You Can Do
-
1
Check for obvious temperature causes
Confirm the door is fully closed, check for recently added warm food, and verify there has been no recent power outage. Allow the freezer 2–4 hours to recover to setpoint.
A freezer loaded to capacity with warm groceries can take several hours to return to 0°F (-18°C). The HI alarm is a normal response during this recovery period.
-
2
Verify actual compartment temperature
Place a calibrated thermometer in the center of the freezer compartment. After 30 minutes, compare its reading to the display setpoint.
If the thermometer confirms the compartment is actually warm (above 15°F / -9°C) and continues to rise despite the compressor running, an underlying cooling fault is likely.
Tools required -
3
Check for other active fault codes
Scroll through the display panel menus to check whether any other fault codes — F2, DEF, FAN, FF — are also active alongside HI.
HI combined with another fault code almost always means the second code is the root cause. Prioritize diagnosing and clearing the root cause fault.
When to Call a Professional
Contact a qualified technician if:
- Freezer cannot reach setpoint despite the compressor running — sealed system or sensor fault
- HI appears consistently overnight or during unmonitored periods with no obvious cause
- HI combined with any other active fault code requiring component replacement
