What people are saying

Rated 5 out of 5 by from So far a great little A/C We bought about 3 months ago and live in Louisiana where is not warm, it’s “Hot”. I’ve used it daily in a small She Shed we built and it works wonderful. 20x18 building with a cathedral ceiling. I keep a ceiling fan going and the A/C at 73 and it’s a perfect temp. So I’m impressed so far!

My LW1217ERSM A/C was just installed. When I look into the machine through the top vents, I see a part (a tube?) that looks like it's covered in cellophane. What is this? And is the cellophane still supposed to be there?

The A/C was installed 3 days ago. How do I open/close the vent? I can't adjust the lever and I can't tell if the vent is closed or open. The lever doesn't move at all when I pull on it or push it in.

HOW DO I REMOVE THE GRILL? When the AC was installed, a step was skipped, the VENT CONTROL LEVER was not pulled out. Now I cannot adjust it and I can not determine whether it is open. (I did not do the installing; that was done by a professional.)

Hello, please see page 15 in the owners manual for steps on the grill. ^AC https://www.lg.com/us/support-product/lg-LW1217ERSM

Can the LG LW1217ERSM a/c be used as a built-in through the wall unit?

Asked by: GramPam
The LG 12,000 BTU Smart wi-fi Enabled Window Air Conditioner, Model # LW1217ERSM requires a standard single-hung or double-hung window for proper installation. The outside of its cabinet must extend outward for at least 12" and there should be no obstacles, such as a fence or wall, within 20 inches from the back of the cabinet because that will prevent heat radiation from the condenser. All its side louvers must remain exposed to the outside of the structure. Restriction to outside air will greatly reduce the air conditioner's cooling efficienct=y and that could also lead to the unit burning itself out. It cannot be installed using a wall sleeve, a hole in the wall, and non-window installations are not recommended...^IFV

Can I disable the wi-fi on window A/C units.

Asked by: Bob1949
The ENERGY STAR® LG 12,000 BTU Smart wi-fi Enabled Window Air Conditioner, Model # LW1217ERSM uses Wi-Fi that allows the user to control the unit with the corresponding LG Mobile app. To use the Wi-Fi and app, the AC must be registered on the SmartThinQ® website. The minimal specifications are for an Android OS 4.0 or higher at 340 x 480 or higher screen resolution or an iOS or higher at 960 x 640 or higher screen resolution. Phones below this minimum specification cannot operate the unit and some phones meeting the above criteria may not operate every function of the unit. The supported routers are Cisco, Apple, ASUS, D-Link, TP Link, Trendnet, Actiontec, Netgear and 2Wire. Other routers may not support the Wi-Fi application. The above models are optimized for Wi-Fi service, but any cell phone that does not meet the minimum system requirements will not be able to run the program...^IFV
