Error codeLo
ApplianceRefrigerator
Quick answer
Lo is a warning about the room, not a failed part. The ambient temperature has dropped below -10 degrees Celsius.
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
Lo is a warning that the ambient temperature has fallen below -10 degrees Celsius and the refrigerator may not run optimally.
When an LG refrigerator displays Lo, the unit is warning you about its surroundings. The ambient temperature has dropped below -10 degrees Celsius.
What the manual tells owners
The manual points out that a refrigerator will not function optimally in an environment that cold. It places Lo among the warnings, separate from the group of codes that indicate a malfunction.
The reverse warning is HI, which appears when the ambient temperature climbs above +50 degrees Celsius.
Other codes worth knowing
rT: a fault in the ambient temperature sensor, which is a different matter from the room itself being cold.
LF: frost on a cooling fan in a kimchi refrigerator, easy to misread at a glance.
