Error codeHI
ApplianceRefrigerator
Quick answer
HI on an LG refrigerator warns that the ambient temperature has risen above +50 degrees Celsius.
Model compatibility: LG reuses codes across series and model years, so HI 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
Ambient temperature above +50 degrees Celsius; the product may not run optimally.
HI on an LG refrigerator is a warning, not a fault. It says the ambient temperature has risen above +50 degrees Celsius, and LG notes that the product will not function optimally in such a hot environment. The code is listed for LG refrigerators generally.
Where LG files it
LG groups HI with codes that may appear on the display but do not indicate a refrigerator fault, next to Demo Mode and the low-temperature warning Lo. The fault codes are the ones where LG says to request service.
An LG refrigerator showing HI in Los Angeles can be booked in at (310) 742-8008. Read out the code and the model number, and say what you tried first. See also LG refrigerator repair.
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.
