Error codeLo
ApplianceRefrigerator
Lo describes the surroundings, not the refrigerator. It shows once the air in the room drops under -10 degrees Celsius.
Warning, not malfunction
LG’s manual places Lo with its warnings, apart from the group of codes that signal something broken. In a space that cold the refrigerator may fail to perform at its best, and that is the whole message.
The hot-side twin is HI, displayed when the room passes +50 degrees Celsius.
Codes it could be mistaken for
A wireless communication problem is Od. A frosted fan on a kimchi unit is LF. For the opposite warning, open HI.

Questions about a refrigerator in the Bay Area can go to (415) 223-7887, or begin at LG refrigerator repair. Say what the display shows, where the unit sits and which model it is.
Model compatibility: LG reuses codes across series and model years, so Lo may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The ambient temperature has fallen below -10 degrees Celsius and the refrigerator may not run optimally.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
