Error codeHI
ApplianceRefrigerator
HI is information, not damage. The room around the refrigerator has grown hotter than +50 degrees Celsius, and in heat like that the product will not function optimally, according to LG. The manual gives it for refrigerators of every kind.
Warning versus fault
LG sorts display messages into two groups. One holds warnings that do not point to a refrigerator fault: HI, Demo Mode, and Lo, which covers a very cold room. The other holds malfunction codes, where the instruction is to request service.
Codes with similar-sounding trouble
If the cabinet itself runs warm, FU describes a freezer that failed to cool. Sensors are covered by FS for the freezer and HS for humidity.
San Francisco LG refrigerator service
An LG refrigerator in the Bay Area that keeps displaying HI can be discussed on (415) 223-7887. Have the model number ready and describe where the unit stands. The LG refrigerator repair page adds background.
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
The ambient temperature is above +50 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.
