Solution

&nbsp;

During the

operation,

1. For safety, put on a pair of cotton work gloves or the rubber work gloves. And find the source of the noise by touching different areas of the railing pipes or

&nbsp;&nbsp; the supporting pipes with your hand.

&nbsp;&nbsp;

&nbsp;- If you find a place where the noise disappears or decreases when touched with

hand

, it can be the possible source of the noise.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp; <img style="border: currentColor; border-image: none; width: 428.79px; height: 221.51px; vertical-align: auto;" src="https://gscs.lge.com:/gscs/support/fileupload/downloadFile.do?fileId=6E4zVQmdy5XgiBBcrPQg&amp;portalId=P1" border="0"/>

&nbsp;

2.&nbsp;

Use a tie strap to bind the noise-generating/vibrating parts of the pipe railing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <img style="border: currentColor; border-image: none; width: 436.6px; height: 209.96px; vertical-align: auto;" src="https://gscs.lge.com:/gscs/support/fileupload/downloadFile.do?fileId=S3XLlcuTDrxfCzqaNAjuXw&amp;portalId=P1" border="0"/>

&nbsp;

Additionally, for

the

2-in-1 the air conditioners and inverter air conditioners, the rotation speed of the outdoor unit motor and compressor changes rapidly.&nbsp;

For

this reason

it may make a ‘buzzing’ noise depending on the room temperature and the desired temperature settings.

This is not a product defect as it’s a normal operating sound for higher cooling performance.

&nbsp;&nbsp;
