      my unit is about 3 years old. When I turn the unit off the compressor stays on sometimes. It only goes off if I unplug the unit. I have read online that this has something to do with arcing on a relay circuit board. Is this problem recalled/warranty?

            Does the 1200 BTU unit require an install kit? if so what's the item # for it?
            ByJun 30, 2024
            2 Answers | 
            Answer This Question

            The LG Window Air Conditioner model LW1222ERSM, which is a 12,000 BTU unit, typically does require an installation kit for proper installation in a window. The specific item number for the installation kit may vary, but it usually includes items like accordion panels to fit the width of your window, support brackets, screws, and possibly foam seals for insulation. To ensure you have the correct installation kit, I recommend checking the user manual or installation instructions that came with your air conditioner. These documents usually include the recommended installation kit item number and details on how to properly install the unit in your window. If you need further assistance or have more questions, feel free to ask! —Renzo

                      Bad packaging
                      Everyone knows that the back of an air conditioner with the fins and coils is fragile. So why would they create a box for the air conditioner that does not protect these fans and coil. Something sharp went through our box during shipment and smashed the fins and possibly damaged the coil. For $400 I wasn’t going to take a chance, so I returned it. Also there were no handles In the shell of the air conditioner so that you could lift it out of the box. While it looks like a nice unit there’s some things that are poorly thought out.

                        Doesn’t work as intended.
                        Install had to be a custom job due to the style of windows, not a problem. Installed easily and quickly, very quit!! Very cold! I purchased this unit for the WIFI….. so my unit could be monitored and times of operation be installed. The app sucks, the WiFi sucks, the connection is absolutely embarrassing. Called Lg and they said they are not responsible for WiFi issues. This unit is less than 10ft from my router… save the money, but a cheap unit.

                            Powerful window unit
                            [This review was collected as part of a promotion.] I've never had air conditioning before, and this window unit is a game changer. It is efficient and takes the edge off in several rooms of my largely open floor plan house. It is narrow enough that I was able to install it in a casement window (after removing the window from its frame). I didnt think i would take advantage of its wifi feature, but it did end up coming in handy many times.

                              This unit runs quiet and keeps my home comfortable; I haven't seen my power bill as yet so can give an update later. So far I am very happy with the product. My house is an older house and this unit was relatively easy to install in the double sash window.

                              So i alresy havw the 8k in my bedroom it keeps the room about 69 at night. I got this 12,000btu for mt living room and so far it does cool the area. I feel like it runs longer than it should for the size and the fan speeds arent much different unlike the 8k unit. Over all its pretty quiet and the air is cold. Setup was a little confusing but i figured it out. You have to remove the guts and install the frame with curtains first.
