What people are saying

Rated 5 out of 5 by from 18,000 BTU works great cools well I have been running this unit for periods of up to 6 days straight in the 93+ temp with 85-90% humidity. The energy feature is great and works well. I have it cooling a space of 900 sq ft and it will maintain the set temperature of 73 just fine.

Rated 4 out of 5 by from Very good for kitchens and large rooms I bought 2 of these air conditioners-one for large living room and one for kitchen. They were easy to install and have done the job I bought them to do. Especially nice during 100 degree days. They are a little noisy, but I don't mind because they keep me cool!!

Rated 2 out of 5 by from Had less than a month and already problems. Bought and installed this on July 1. By July 15 the "Energy Saver" mode quit working right - the fan would kick off and never come back on. Tried to schedule a warranty repair online and could not because the "Direct Care" feature isn't currently available. If I am able to get service scheduled through Customer Service, and the unit is repaired, I may re-evaluate my rating. At this point, though, I would hesitate to purchase another LG product.

We appreciate your interest in this air conditioner. Unfortunately, the unit only displays in Fahrenheit, it would not be possible to change it to Celsius.

Why has my fan stopped blowing cool air?

After the unit runs and cools just fine for a few minutes, the unit stops blowing cool air. The unit is still running and the temperature gets lower on the display. When I turn the unit off the compressor continues to run. I unplug the unit from the wall and after a few minutes, the compressor finally shuts off. After leaving it unplugged for a few minutes, I plug it back in and it works fine for a little while and then it stops blowing cool air out again.
Asked by: TrinaMeredith
Hi TrinaMeredith, we regret to read that your LG 18,000 BTU Window Air Conditioner with remote, Model # LW1812ER may be operating erratically. When you set the desired temperature on the Air conditioner, it might take the Air Conditioner about 30 minutes for it to lower the temperature by 2°F and then another 30 minutes to drop another 2°F. If the Air Conditioner is underpowered, meaning if it is too small a unit for the room size, the compressor will keep running and the room never cools. These explanations may not apply to your Air Conditioner, but those are some causes for the Air Conditioner's compressor running as you have described. It may be that you may need to get a repair service on the Air Conditioner. Try setting the temperature at it's lowest setting and turn the fan to its highest setting and the air should be cold. If not, that would indicate the unit needs to be serviced...^IFV

There is a little red light flashing next to power button what does this mean

It is not listed in the manual but was does it mean when the red light next to power is flashing?
Asked by: Anonymous
This is normal operation for this air conditioner. On some of the newer LG air conditioners, the power indicator will begin to flash when it is time for the filter to be cleaned. You can reset the indicator by unplugging the unit for approximately 3 minutes and then restoring power to the unit.
