GE Refrigerator Error Code Lo

"Lo" appears on the outside temperature indicator of a GE refrigerator when the ambient temperature around the unit drops below -10°C (14°F). The display cannot show a numeric value below that threshold, so it substitutes "Lo" instead. This is typically an informational alert rather than a fault code, and it often occurs when the refrigerator is placed in a very cold unheated space. The display should return to a normal numeric reading once the surrounding temperature rises above -10°C.

The "Lo" display itself does not indicate a dangerous condition, but operating a refrigerator in very cold ambient temperatures can affect its performance and longevity. Most refrigerators are not designed to operate reliably when surrounding temperatures fall below freezing, as this can impact compressor lubrication and sealed system efficiency. If the unit is in a space regularly reaching these temperatures, consider moving it to a more temperature-controlled location.

If the cause is simply cold ambient temperature, there is no repair cost involved. If the ambient temperature sensor needs replacement, parts typically range from $15 to $60 depending on the specific model, with professional labor adding $75 to $150 or more depending on your location and service provider. Wiring harness repairs can vary widely based on the extent of the damage.

If the refrigerator is in a cold garage or unheated room, the most straightforward fix is to warm the surrounding environment or relocate the unit to a heated space. If ambient temperatures are already above -10°C and "Lo" persists, inspect the ambient temperature sensor and its wiring harness for damage, corrosion, or loose connections. Replacing a faulty sensor should resolve the display issue.

A reset will not clear the "Lo" display if the ambient temperature around the unit is still below -10°C, because the sensor is actively reporting a real temperature condition. The display will only return to normal once the surrounding temperature rises above the threshold or, if the sensor is faulty, after the defective sensor or wiring is repaired. Resetting the refrigerator by unplugging it briefly may be a useful troubleshooting step to rule out a control board glitch, but it will not resolve an underlying sensor or environmental issue.
