What people are saying

Rated 1 out of 5 by from 100% DO NOT BUY We bought this unit about 3 weeks ago and has been a waste of money and it doesn't cool anything. When we called customer service they informed us that the unit doesn't cool unless it's greater than 70 degrees faranheit. Well guess what, it's above 70 and it's still not cooling. It seems they believe if its 70 oitside its 70 inside which is not the case. If you want your room to be cool, I suggest looking else where.

Rated 1 out of 5 by from Not good at all I spoke with the technician and I was told because the item was fairly new that they had to replace it with a new one and never heard back from him after that point

This unit is 6-15 R plug, the outlet is 5-15 P outlet. Do I get an adapter?

Asked by: Cynthia O
You cannot use an adapter for the 6-15P plug on the LG 12,000 BTU 230v Through-the-Wall Air Conditioner, Model # LT1236CER to plug it into a 5-15R outlet. Not only will you not find that type of adapter, but a 5-15R outlet does not have the correct voltage. A 5-15R outlet is rated at 125V. The unit requires a standard 250V, 3-wire grounding receptacle rated at 15A, 250 V AC. It will not work at 125V...^IFV

The ENERGY STAR® LG 12,000 BTU 230v Through-the-Wall Air Conditioner, Model # LT1236CER has a width of 24", a height of 14.41" and a depth of 20.09".

The width and the depth for the sleeve that you gave dimensions for are too narrow and this unit will not fit into those dimensions...^IFV
