7 Common Problems with LG Air Conditioners (Must Know)

Here’s our list of the 7 most common LG Air conditioners problems with solutions.

LG Air Conditioner Not Cooling

From time to time, LG air conditioners can stop cooling the air they blow out

If your LG Air Conditioner is not cooling, or not blowing cool air it’s likely to be a clogged air filter or defective thermostat.

However, you don’t need to worry, as reading the causes and solutions below might help you solve the issue.

Possible Solution(s):

Thermostat

If your LG air conditioner is blowing hot air, the thermostat may have been set to “heat” by mistake. If this is the case, it’s a simple remedy that you can do on your own.

Simply turn the thermostat to “cool” and observe if the air conditioner starts to blow cool air once more.

Check the thermostat and make sure it is set to “cool” and at the proper temperature. If it needs new batteries, replace them.

Check the thermostat and make sure it is set to “cool” and at the proper temperature. If it needs new batteries, replace them.

Dirty Filter

A dirty air filter can lead to a dirty evaporator coil, even though air filters have nothing to do with air temperature.

There may not be enough free airflow to allow for efficient cooling operation if the evaporator coil becomes blocked with dust and debris.

Debris build-up from a filthy air filter can cause frozen evaporator coils.

Although you may believe that “frozen” equals “cold,” the frozen coils actually obstruct the flow of cool air, causing warm air to flow from the running engine instead.

Depending on the environment, filter type, and home, air filter change should be done every 30-60 days by the owner.

Setting a monthly reminder to check the condition of your air filter is recommended.

LG Air Conditioner Not Turning On

At times, your LG Air Conditioner won’t turn on, no matter what buttons you press.

If that’s the case, LG Air Conditioner not turning is typically caused by a simple power failure or tripped circuit. 

Try not to fret, instead work through the steps below

Possible Solution(s):

  • If you’re lucky, your Air Conditioner might be having trouble turning on only due to a simple power failure such as a loose power cable or a tripped circuit breaker.
  • So, check the main power cable of your Air Conditioner along with its circuit breaker switch, making sure both are in place.
  • If the Air Conditioner appears to be getting a constant supply of electricity, then the problem might be inside your Air Conditioner’s system.
  • Your Air Conditioner may have some broken wires that are not allowing current to pass.
  • To fix this issue, you will need to call a professional.

It’s expected for an LG Air Conditioner to produce water through condensation.

However, if you start to notice water puddles and excess water leakages, there’s something wrong with your Air Conditioner.

What do the reviews say?

I stop using Air Conditioner in my room. I only have two windows in my room.

It made my room dark, and I couldn’t just lift and take it out, so on cool nights, I just had one window.

Three years ago, my son got an LG. He loved it.

So easy to use. Has a unit inside, and all you need to put in a window is the hose. So I got two 3 years ago.

Last year bought my niece one.

Depending on the size of the room is how you decide which model to get.

We all love them.

This air conditioner is just perfect for us. It’s whisper quiet and very efficient.

We’ve used the timer several times and always come home to a cool house.

It’s cooling a wide-open first floor on the economy setting.

Haven’t learned how we use the feature that allows you to control it with your phone, but the grandkids are going to help us with that. Very satisfied so far.
