LG Refrigerator (Top Freezer) HI error code

Difficulty: Easy · Cost: $0 · Duration: Clears automatically when ambient temperature drops

HI is not an error code. It is a warning that the ambient temperature in the room where the refrigerator is installed has risen above 50 degrees Celsius. Operating in extreme heat puts significant strain on the compressor and cooling system. LG refrigerators are not designed to function correctly in environments this hot. The warning will clear once the ambient temperature drops back to a safe operating range.

Common causes

Refrigerator is installed in a very hot environment or in direct sunlight
Ambient room temperature has risen above 50 degrees Celsius
Poor ventilation around the unit causing heat to build up

How to fix it

1

Move the refrigerator to a cooler location away from direct sunlight or heat sources
2

Ensure there is adequate ventilation around the unit — at least a few centimetres of clearance on all sides and at the back
3

The HI warning will clear automatically once the ambient temperature drops below the threshold
