GE Refrigerator Error Code Lo

The "Lo" display on a GE refrigerator's outside temperature indicator is not a malfunction code in the traditional sense. It is an informational alert that appears when the ambient temperature surrounding the refrigerator falls below -10°C (14°F). The external temperature sensor monitors the environment around the unit, and when readings drop below this threshold, the display substitutes the numeric readout with "Lo" to indicate the sensor is detecting conditions outside its normal display range.

This condition most commonly occurs when the refrigerator is installed in an unheated space such as a garage, basement, or utility room during cold weather months. The outside temperature indicator is designed to display ambient readings within a specific range, and sub-threshold temperatures simply exceed the lower boundary of that display range. The refrigerator itself may continue to operate, but performance can be affected at very low ambient temperatures, as the compressor and sealed system are typically rated for operation above freezing conditions.

No component failure is necessarily indicated by the "Lo" display. The ambient temperature sensor is functioning correctly and reporting an accurate reading that falls outside the displayable range. If the ambient temperature rises above -10°C, the numeric display should return automatically. If "Lo" persists despite warm surroundings, the external temperature sensor or its wiring circuit may warrant inspection.
