The "HI" on your LG wired remote is not an error code. It simply indicates that the current indoor temperature is unusually high (above 35.5℃ / 96℉). This message will disappear once you run the air conditioner in cooling mode and the room temperature drops.
Please Note
- If your room is not hot, but the remote still displays "HI", there may be an issue with the temperature sensor. In this case, contact LG Support for assistance.
Why "HI" appears on the display
High indoor temperature: If the air conditioner detects that the room temperature is above 35.5℃ (96℉), "HI" will appear on the display to indicate a "High" temperature.
What to do when you see "HI"
This is not a malfunction. Simply follow these steps:
Step 1. Turn on Cool mode
Turn on the air conditioner and set the mode to Cool.
Step 2. Lower the temperature
Set your desired temperature lower than the current room temperature.
Step 3. Check the display
Once the room temperature drops below 35℃ (95℉), the "HI" message will disappear and the current temperature will be displayed.
