What people are saying

Rated 4 out of 5 by from Great features I have had my air conditioner for almost 5 years and it has worked great until this year. I believe the ac motor is bad and everywhere I have tried to find the part I have been told that it is no longer being manufactured. I am only on social security and cannot afford to purchase a new unit and have no money for a repair person.

Rated 5 out of 5 by from quick set up refreshing results set up was a breeze. cools my entire office in seconds, no maintenance required. the only thing is it a bit on the heavy side

Rated 1 out of 5 by from Not any good (I'm trying to be polite) On a hot day it will repeatedly shut down with a ch34 error which means high pressure in the condenser. Getting it going again requires unplugging and re-plugging to reset. The unit is shaded from direct sun and even though it's a new unit I have cleaned the coils. When it's working it works and cools fine, cycling on and off as you would expect.

When i turn it off something keeps running

Asked by: Eliasg
Do you have any error codes showing on the display for the LG Window Air Conditioner, Model # LW2515ER. The Air Conditioner will display an error code for some problems you are likely to encounter that can be easily resolved with a little troubleshooting. Regrettably, without a description of of the "something keeps running" when you turn the unit off, it cannot be determined what the issue may be. The 'Troubleshooting' section on page 22 of your oner's manual describes some sounds and possible causes that you can review to see if they describe what you are describing, otherwise, the unit will need to be inspected by a qualified technician to determine what the issue is. If you see “CH” in the display, please call 1-800-243-0000...^IFV

I purchased our LG LW2515ER from Home Depot approximately 3 1/2 years ago. The compressor does not disengaged after reaching the set temp. Energy Saver, fan turns off but the compressor stays on. Have to unplug to stop cooling. Fan mode - compressor on.

Can this unit be refilled with stuff to make it colder again? Not sure how old it is.

Asked by: Fisher67
We regret the trouble you have experienced with this air conditioner. This model has been designed as a Sealed System machine, meaning that it does not have a refill valve available. If this is not cooling properly, then the air conditioner may require service. To make service arrangements, you may either contact our Customer Interactive Center at 800-243-0000, or you can check our Repair Provider Lookup on our website, at

I have a problem with my LG LW2515ER window unit not cycling correctly. When it is suppose to shut off, there is a motor that keeps running and my wife has to shut it down manually to get it to turn off. The issue came up 1 week after the 1 year warantee.

Asked by: AJCunniff
We regret the trouble you have experienced with this air conditioner. During the normal COOL cycle, it is normal for the fan motor to continue running, even after the compressor stops running. Activating the ENERGY SAVER mode will allow both portions of the air conditioner to stop simultaneously. If this is not the case you have experienced, please contact our Customer Interactive Center at 800-243-0000.
