Hey so my LG window air conditioning unit stopped blowing cold air. It basically only works as a normal fan now. When I switch it to the COOL function, the fan continues to blow, then when the compressor kicks in, it sounds like its working hard, then it just shuts off after a couple of seconds. Then after another 10 seconds or so, it tries to come back on and shuts off again.
Does it sound like I need to change out the compressor?

That's what it sounds like. How many amps does it draw? I can't get anything to come up with that model number.

Before you condemn the compressor, make sure the condenser coils are clean and the air vents on the sides are not blocked by leaves, dirt, or other debris. Clean the condenser coils with a garden hose by spraying the coils from the back of the air conditioner. Hope that helps!

That will not do anything to help the compressor run. If they can get it running then they can clean the a/c if needed.

It sure will. By their description the compressor is running, overheating, and shutting down. A dirty condenser will cause that.

The OP said, "it just shuts off after a couple of seconds".

It takes a lot longer than a couple seconds for a compressor to overheat from a plugged condenser, 5-10 minutes at least. If the compressor will run for 5 to 15 minutes or more, then cleaning the a/c might be warranted.

There's little use putting in the effort of cleaning if the compressor is faulty.

I agree with Dan. If it shuts off after a few seconds of running, condensor is not the problem. Most compressors won't get hot enough to open an overload just from a dirty or blocked condensor. That's why I asked about the amp draw.
