Answer to continue safely
Is it safe to keep using?
Yes. Food remains safe when the freezer is too cold, though quality may suffer. Extremely low temperatures can cause freezer burn and make items brittle. The main concern is increased energy consumption and accelerated compressor wear.
Can I reset the code?
Yes. Press the alarm reset or mute button on the control panel to silence the buzzer. Adjust the temperature setting to the recommended level. The LO alarm should clear once the internal temperature rises above the lower alarm threshold.
When to stop immediately?
Stop if you notice: Stop adjusting settings and call a technician if the compressor does not cycle off at all, even after raising the temperature setpoint., Do not attempt to access or modify the thermistor wiring without disconnecting the freezer from power first..
Symptoms You May Notice
LO displayed on control panel
The control panel shows the LO alarm code, indicating the internal temperature has dropped below the acceptable lower limit.
Excessive frost and ice inside the compartment
Thick frost forms on the walls, shelves, and food packaging because the freezer is running much colder than the setpoint.
Food items are extremely hard and brittle
Frozen foods become excessively rigid, and items like ice cream are too hard to scoop even after sitting out briefly.
Compressor running almost continuously
The compressor rarely or never cycles off because the control system keeps requesting more cooling despite already low temperatures.
Possible Causes
Faulty temperature sensor or thermistor
A defective thermistor sends inaccurate warmer readings to the control board, causing the system to overcool the compartment.
Requires ProfessionalTemperature setting too low
The digital or dial temperature control has been accidentally set to the coldest possible level, driving the compartment temperature far below normal.
DIY PossibleMalfunctioning control board
The main electronic control board fails to cycle the compressor off at the setpoint, allowing continuous cooling beyond the intended range.
Requires ProfessionalSafe Checks You Can Do
-
1
Verify the temperature setting
Check the freezer temperature control on the display panel and set it to the recommended level of approximately -18 degrees Celsius.
On some Electrolux models, pressing and holding the temperature button for three seconds enters the adjustment mode.
-
2
Place an independent thermometer inside
Put a standalone freezer thermometer in the center of the compartment and wait four hours, then compare the reading to the display.
A difference of more than five degrees between the independent thermometer and the display suggests a faulty sensor.
Tools required -
3
Listen for compressor cycling
After adjusting the temperature setting, listen over the next few hours to confirm the compressor cycles off periodically rather than running non-stop.
A healthy freezer compressor typically runs for 30 to 40 minutes and then shuts off for a similar period.
When to Call a Professional
Contact a qualified technician if:
- The compressor runs without stopping for more than 12 hours despite the temperature control being set to a moderate level.
- An independent thermometer confirms the freezer is at -30 degrees Celsius or colder while the display shows a different reading.
- The thermistor resistance measured with a multimeter does not match the manufacturer specification for the actual temperature.
