Answer to continue safely
Is it safe to keep using?
Yes. A low temperature alarm does not pose a safety risk. The ice maker can continue operating, though ice quality may be affected. Adjust the temperature setting and monitor for improvement over 24 hours.
Can I reset the code?
Yes. The LO alarm clears automatically when the compartment temperature rises above the minimum threshold. Adjusting the temperature setting upward or improving ambient conditions should resolve it within hours.
When to stop immediately?
Stop if you notice: The water supply line has frozen solid and no new ice is being produced, The evaporator is completely encased in ice after a manual defrost attempt.
Symptoms You May Notice
LO flashes on the temperature display
The control panel displays LO instead of a numeric value, indicating the internal temperature sensor is reading below the minimum threshold.
Ice cubes are cracked or shattered in the bin
Excessively cold temperatures cause ice cubes to develop internal stress fractures, producing cracked or broken cubes when harvested.
Water supply line freezes
The water inlet tube inside the unit freezes solid, preventing new water from entering the ice mold and halting production entirely.
Heavy frost buildup on the evaporator
The evaporator coil develops a thick layer of frost because the compressor runs too long between defrost cycles, reducing airflow and cooling capacity.
Possible Causes
Temperature set too low
The user-adjustable temperature control has been set lower than necessary, causing the compressor to cool the compartment beyond the optimal range.
DIY PossibleFaulty thermistor or thermostat
The temperature sensing element has drifted out of calibration, reading warmer than actual temperature and causing the control board to request continuous cooling.
Requires ProfessionalAmbient temperature too low
The unit is installed in an environment below 50°F (10°C), causing the refrigeration system to over-cool the compartment because the control logic is designed for warmer ambient conditions.
DIY PossibleSafe Checks You Can Do
-
1
Check and adjust the temperature setting
Press the temperature adjustment button on the control panel. Set it to the factory-recommended level — typically the middle setting. Wait 4-6 hours for the compartment to stabilize at the new setting.
Electrolux recommends a storage bin temperature around 15°F (-9°C) for optimal ice quality.

2
Verify the room temperature
Place a thermometer near the ice maker installation location. If the ambient temperature is below 50°F, the unit cannot regulate properly. Move it to a climate-controlled space or raise the room temperature.
Garages and unheated basements in winter are the most common location issues.

Check for frost on the evaporator
Open the ice maker door and look at the evaporator area (behind the ice mold tray). If it is coated in thick frost, turn the unit off for 2 hours to allow a manual defrost, then restart.
A thin layer of frost on the evaporator is normal — a thick ice buildup is not.
When to Call a Professional
Contact a qualified technician if:
- The thermostat clicks off but the compressor continues running, suggesting a stuck relay
- Temperature readings on the display do not match an independent thermometer placed inside
- The unit was recently serviced or had a part replaced before the LO alarm appeared
