[LG air conditioner leakage] [Heating] There is a water leak from the outdoor unit. White steam comes out

Troubleshooting

Unlike during cooling, the heating operation switches the roles of the outdoor and indoor units to heat, so cold air comes out of the outdoor unit when it is used in winter.
At this time, moisture in the air adheres to the surface of the evaporator in the outdoor unit, causing frost.
If there is a lot of frost on the outdoor unit, the heating capacity is degraded, so, the [defrosting function] is performed and water drips down and becomes white water vapor/steam as frost melts.

Stand-type air conditioner: preheat/defrost, wall-mounted air conditioner: preheat/defrost, * mark and droplet preheat/defrost

Defrosting completed

After the defrost operation is completed, water is formed in the outdoor unit.
Note
During the defrosting operation, warm air stops and cold refrigerant flows to the indoor unit, which may cause a contraction/expansion noise.
This is a normal process of the defrosting operation, so rest assured, it is not a product defect.
