There are various reasons why your LG air conditioner may not be cooling the way it should, but there are also many ways to fix this issue.
Air conditioners can create a cool oasis on even the warmest of days, but this does not mean that they always operate the way that they are supposed to.
Fortunately, there are plenty of troubleshooting tips to try if your LG air conditioner is not cold enough.
Why is my LG air conditioner not cold?
There are few things more frustrating than realizing that your air conditioner (AC) is just not getting cold enough on a warm day.
LG ACs often display error codes when there is something wrong with the way that your window, mini-split or portable unit is working. In this case, you can simply follow the helpful prompts on the LG support website.
However, there are also other things that you can do to check and improve your AC’s cooling, even if the AC has not picked up that there is an issue yet.
Your first step with these kinds of problems should always be to check your AC’s power supply.
Ensure that the AC is plugged in properly, that the outlet is working and that the air conditioner turns on before you proceed to any of the following steps.
Check that your temperature is set correctly
Your settings will influence how and when your AC works. When you switch the AC on, ensure that it is set to “Cool” mode by pressing the “Mode” button on your remote control or the display panel.
Then ensure that you have set the temperature to the lowest possible number.
Clean your air filters
Dirty filters will prevent the cool air from flowing freely into your room and can cause undue strain on the unit.
If you notice that your LG AC is not working as effectively or efficiently as it used to, has a musty odor, or that the room’s humidity level is higher than normal, then it may be time to clean your air filters.
You can use a humidity gauge, like this ThermoPro TP50 Digital Hygrometer to measure the humidity level of your space.

Your air filters should be cleaned every few weeks by carefully running over the removed filters with a vacuum or a soft brush and some lukewarm water to remove any dirt or debris.
Perform a compressor test
You can test the compressor in your unit by unplugging the AC from the outlet entirely for 30 seconds to a minute.
Then, plug the AC back in and turn it on, set it to “Cool” at the minimum temperature, and set the fan speed to the maximum.
If your compressor does not turn on within a minute, this indicates that there may be a serious problem with the unit. Hence, you may need to contact a professional for assistance.
