It is unusual for LG air conditioners to make a beeping sound, but this may be caused by the compressor, another underlying issue or changed settings.
It can be frustrating when your air conditioner (AC) is not working the way that it is supposed to, but fixing underlying issues quickly can help you avoid extensive damage.
Some LG mini-split air conditioners may beep if the desired temperature is set too low, but a beeping sound could also be caused by an alarm or a change in the desired settings.
When your air conditioner is not working as it should
It can be annoying enough when your air conditioner is displaying an error code or indicator light to warn you about internal issues with the components.
But it can be even worse when you have no idea why your air conditioner is not working or not cooling as it should.
Air conditioners are complex appliances and running these machines when there is some sort of internal issue can put unnecessary strain on the components. In fact, it may even shorten the lifespan of the entire unit.
LG air conditioner beeping error
Air conditioner manufacturers like LG usually have extensive systems to keep track of all of the warning lights and error codes which are used in all of their different models.
This is why it is always best to consult your owner’s manual if you are experiencing any kind of issue with your air conditioner.
For instance, many of the LG mini-split units tend to make a beeping sound in the outdoor unit if the disparity between the desired temperature that you have selected, and the actual ambient temperature of the room is too large. This beeping is caused by the high-speed operation of the outdoor unit.
As a result, the beeping should stop once the temperature of the room has started cooling down, or once you have increased your desired temperature by a few degrees, so that the compressor does not have to work quite as hard to make up the difference.
However, if the beeping does not stop (or the beeping is not coming from the compressor), this beeping could be caused by a more complex issue.
In this case, your first troubleshooting step should be to investigate whether this beeping may be warning you about a fault or error with one of your AC’s components.
If there are seemingly no obvious issues with any of the components, your best bet may be to just reset the entire unit in the hopes that this will get rid of the beeping sound.
But, if you find that the beeping only happens when you press buttons or change your settings, there may be no way to avoid this sound, unless you have a newer, inverter-type air conditioner (which has a mute button built into the remote control).
Common LG air conditioner issues
Before you start resetting or muting your air conditioner, it is worthwhile to ensure that the beeping is not actually an alarm warning about some bigger issue.
Some of the most common issues that LG air conditioners experience (which can be easily checked) include:
- Dirty air filters
- Dirty condenser coils
- Disconnected remote control
- Frozen condenser coils
- Blocked drain
- Fan blade obstructions
- Low refrigerant levels
How to reset your LG air conditioner
A continuous beeping sound is unusual for LG air conditioners, and it can become quite annoying after a while.
Fortunately, resetting your air conditioner is often a good solution when it seems like the unit may have gotten confused or will not clear an error.
To reset an LG air conditioner, all you really have to do is switch the unit off and unplug it (or turn it off at the breaker if this is easier). Then, simply wait at least 30 seconds before plugging the unit back in and switching it on again.
How to mute the LG inverter-type air conditioners
There is really no way to turn off the beeping sound that most of the older LG air conditioners make when you press their buttons. However, LG has addressed this issue in some of the newer inverter-type air conditioners.
Inverter air conditioners are more energy efficient, more eco-friendly and more cost-effective than traditional AC units and if your remote control includes a “Mute” button (which is usually located in the top right corner of the remote control) your air conditioner will also be able to operate more quietly.
If you want to mute this type of air conditioner, all you have to do is to press this mute button. This will ensure that no beeping sounds are emitted while you change the settings on your air conditioner.
