LG Refrigerator LO Code — Low Ambient Temperature Warning
What this means
The LO code appears when the ambient (room) temperature drops below approximately 14 degrees F (-10 degrees C). The refrigerator's compressor and thermostat are designed to operate within a specific ambient temperature range. In extremely cold environments like an unheated garage in winter, the compressor may not cycle properly, leading to the freezer thawing or the refrigerator section freezing.
Step-by-step fix
1 stepsMove or heat the space
If possible, move the refrigerator to a temperature-controlled indoor space. If it must stay in a garage or basement, consider adding a space heater or insulation to keep the ambient temperature above 50 degrees F.
Most refrigerators are designed to operate in ambient temperatures between 55-110 degrees F.
