Why does my LG ARUN Air Conditioner show a high pressure error at cooling?

If your LG Air Conditioner's outdoor fan shows a high-pressure error during cooling, it could be due to a motor failure or poor ventilation around the outdoor heat exchanger. First, turn off the outdoor units for a while and then check if the outdoor fan is working. Also, make sure there are no obstructions blocking airflow around the outdoor units.
