Hi there. The energy saver light is always green when it's on. It turned to orange once I had it off for a bit then turned it back on. Is that normal? 

Asked by: Hollie
We appreciate your interest in this air conditioner. We might be able to make more of a determination as to what is occurring with this machine if there were more information on how long the unit was inactive before starting it again, as well as the condition of the air filter at that time. Please contact our Customer Interactive Center at 800-243-0000 for more assistance.

I have a window unit LW1815ER. There is a vent lever sticking out of the vent (where air comes out) to open or close the vent, not the levers that change the direction of the air flow. I was wondering what is it for, not sure when it should b open & close

Asked by: myaige
According to the information listed on page 18 of the owner’s manual, the ventilation lever must be pressed in, for the CLOSED position, in order to maintain the best cooling conditions. When some measure of fresh air is necessary in the room, set the ventilation lever to the OPEN or OUT position.

 We have recently purchased the lw1815er and it works great! Just wondering if the unit can read the room temp instead of displaying the set temp? 

Asked by: tatordevoe
I apologize, but no; the temperature set in the display will only show the set temperature. It will not display the current room temperature.

Lost my owner's manual. How do I reset the clean filter light. I cleaned the filter, but the light is still on.

Asked by: Vicster
Hold the temperature buttons(up and down arrows) at the same time. This should reset it.

I see no reason at all why this unit could not be installed in a wall, given that the opening dimensions H x W are appropriate.

I see no reason why this unit could not be installed in a 6 inch wall. Would there be an issue with the louvers being blocked?
Asked by: Jeffrie
The installation instructions provided in the owner's manual for the LG Window Air Conditioner, Model # LW1815ER only describe installation of this unit in a window and we can only advise you on installations that are consistent with those instructions. Forgoing those instructions is discretionary but you should also be aware that installation of the unit in a manner that is not consistent with that as described in the owner's manual voids any warranty on the unit...^IFV
