[LG air conditioner heating] The outdoor unit does not operate. After indicating defrosting operation in progress, cooling is suddenly stopped

Troubleshooting

Defrosting is a function to thaw frost in the outdoor unit that occurs during heating.
At the moment, defrosting is switched to cooling for a while to melt the ice stuck in the outdoor unit, and the fan stops to prevent cold air from entering indoors.
It is normal, so you can use it with an easy mind.
If the indoor temperature is higher than the target temperature, the outdoor unit will stop running.

Try this

You can see the phrase [defrosting] on the display window of the air conditioner during the defrosting operation.
In addition, during defrosting operation, frosts on the outdoor unit will melt and water will flow to the floor, and as a result, white steam can be seen. Because frosts are melted instantaneously, you can hear the ice breaking sounds temporarily.
If the neighboring temperature drops suddenly, it takes longer to warm the pipe, and as a result, the indoor temperature will not be changed quickly and on a snowy or wet day, there would be more frosts on the outdoor unit, thus defrosting operation will take place more frequently and the overall cooling performance will be degraded.

※ The defrosting and preheating display may differ by model.

Press the indoor temperature button on the remote controller to check the temperature.
But, if the outdoor unit does not operate when the target temperature is higher than the indoor temperature, then inspection is required.
