If your LG air conditioner is not blowing cold air, check the operating
mode, the airflow around the outdoor unit, and the filter condition.
You can resolve most cooling issues by switching to Cooling mode,
clearing the area around the outdoor unit, and cleaning the filter.
Use your remote control to select Cooling mode. Set the temperature to
18°C (64°F) and the fan speed to High. Turn off any energy-saving or
low-noise mode. Let the air conditioner run for at least 30 minutes.
Make sure the outdoor unit turns on and check whether the air feels
cold.
Remove any objects around the outdoor unit to improve airflow. Install
a shade if the unit is in direct sunlight.
Lightly spray water on the back of the unit to cool it down and
improve cooling performance.
Remove the filter. Use a vacuum to remove dust, or wash the filter with water if the filter is washable. Clean the filter every two weeks. Move any curtains or blinds blocking the indoor unit’s air intake.
If the issue persists after following the steps above, you can get further support through LG Chatbot on our website or by requesting a technician visit.
On models released in 2024 or later, cooling may feel weaker if Energy
Saving Planner is turned on in the LG ThinQ app.
This feature
controls power consumption during cooling. For cooler air, open the LG
ThinQ app and select Useful Features, Energy Saving Planner, and
Delete Settings.
