What people are saying

Rated 2 out of 5 by from Not happy My brother bought this unit for us Memorial Day weekend of 2018. Yesterday, the motor completely locked up and the fan won’t come on or cool. Not very happy with this product right now. Up until this point it has kept my trailer cool. Don’t u defat and why it locked up when it’s not even a year and a half old.

Does this air conditioner draw fresh air from outside to the room or it's just recycling the air indoor?

Asked by: Sim0n
The LG Window Air Conditioner, Model # LW1514ER has a Ventilation Lever on it that must be in the CLOSE position in order to maintain the best cooling conditions. However, when fresh air is necessary in the room, this lever can be set to the OPEN position and a damper is opened and room air is drawn out...^IFV

The part that says clean filter has a red ligjt, i cleaned the front filter and i still didnt go off is there another filter

Asked by: Lisha
This flashing red indicator light is a normal operation for certain models. On some newer models, the POWER INDICATOR will begin to flash when it is time for the air conditioner filter to be cleaned. It is possible to reset this indicator light by unplugging the unit for approximately 3 minutes, and then restoring power to the system.

The instructions shows the ventilation lever must be closed on order to maintain best cooling. I cannot locate the lever like in the diagram. Where is it?

Asked by: Fays1
We appreciate your interest in this air conditioner. The ventilation lever is located within the air exhaust duct. It is a small, plastic stick which can be pulled outward or pressed inward to control the internal vent.

I too would also like to know if this unit can be wall, versus window mounted.

I just watched the video that accompanies the information for this unit, however, the video does not really apply to this unit because the video specifically states that it is for 8,000 - 10,000 BTU units. It then gives a "disclaimer" that "installation of a 12,000 BTU unit may differ"; no where does it make reference to a 15,000 BTU unit, which is what this unit is. The video says do not wall mount this unit, but as I just stated, it refers to 8,000 - 10,000 BTU units. I'm thinking the reason a unit should not be wall mounted is because wall mounting may block the vents. However, if ALL the vents are free from blockage and accessible, can't the unit be mounted in a wall versus a window? Thank you.

I have an older LG 15,000btu window unit mounted thru a wall in a mobile home for about 5 years with no problems.I installed it myself.

My unit won't cut on could it be the breaker voltage cause I plug my fan up and it works fine 

Asked by: Jbird23
We regret the trouble you have experienced with this air conditioner. Yes, it is possible for the amperage of the circuit to affect operations of this air conditioner. It is for this reason that a dedicated circuit of 125V @ 60Hz with a 15A fuse is recommended for operations.

I have this unit on my property (apartments) which unit do you recommend for a replacement?

Asked by: Roberta Bonfiglio
We appreciate your interest in this air conditioner. If a 15,000 BTU air conditioner is needed, then it may be possible to locate the newer model LW1515ER. This model can be reviewed on our website at http://www.lg.com/us/window-air-conditioners.

Air conditioner amp usage

Does this unit use different amperage when running? How much amperage does this draw when running but not cooling, and how much amperage does this draw when full cooling (compressor) is running?
Asked by: BryanB15845
BryanB15845, we appreciate your interest in the LG Window Air Conditioner, Model # LW1514ER. This unit is listed at 12.0 Amps but that probably is the amperage for the unit when it is running. The amperage for when the compressor kicks on or when the unit is just running is not specified but can be calculated from the information that is on the data template that is attached on the unit. On that data tag, you will find the FLA (Full Load Amp) rating for the fan which is usually around 1 amp so that does not consume that much power. You will also find on the data tag is the RLA value, this is the Rated Load Amps and is the amount of current (amps) your compressor should consume if it is operating normally. You may also have an LRA (locked rotor amps) value. This is how many amps your compressor would consume if for some reason it jammed up and it is the maximum possible amperage draw of the compressor. Once you have those amperage values for your compressor and fan, add them together and that is how many amps the unit as a whole consumes when it is running...^IFV
