[LG Air Conditioner Frost][Heating] There is frost in the outdoor unit.

Troubleshooting

What is defrosting?

The function is used to melt frost accumulated in the outdoor unit during the heating process.
Air conditioner says pre heating and defrosting and as the air conditioner stops for a moment and hot wind comes from the outdoor unit, thus automatically meting frost.
During the process of frost melting, steam may be generated or water may drip from the outdoor unit.

※ The defrosting and preheating display may differ by model.

Is there white frost on the rear of the outdoor unit?

➔ It is normal.

Once you start heating, there will be cold wind from the outdoor unit as much as hot wind from the indoor unit, thus the rear of the outdoor unit will accumulate frost on it.
On a rainy or snowy day with high humidity, more frosts will be formed and the cycle operates to detect the amount of frost for automatic defrosting, and meanwhile,
heating is temporarily paused and the product says preheating/defrost.
