LG air conditioner “clean filter” light won’t go off

You can reset your “clean filter” light using the temperature buttons, the fan button, or resetting your unit if it will not turn off.

LG air conditioners are good value for money, because they have a variety of models that have many useful built-in features.

However, this does not mean that LG air conditioners do not have faults. Many customers have found that their units’ “clean filter” lights will simply not turn off, but there are various solutions to this issue.

Are LG air conditioners worth buying?

LG is one of the most internationally well-known brands when it comes to appliance manufacturers in the world. This South Korean brand has also made a name for itself in the air conditioning market.

LG offers a wide range of sleek air conditioners, ranging from window air conditioners to portable air conditioners, all of which are energy-efficient, low-noise units that include smart features such as mobile application compatibility.

This, paired with their sleek designs, makes LG air conditioners fairly good value for money.

LG air conditioner “clean filter” light won’t go off

Even though LG is such an established brand when it comes to air conditioners, there are still instances when LG air conditioning units will give slight issues or problems.

One of the most common issues that users experience with their LG air conditioners is that the “clean filter” light at the top of the unit does not switch off even after the filter has been removed and cleaned.

This light was intended to be a convenient way to remind AC owners that they need to clean the air filters in their units regularly.

However, it can be annoying when this light will not go off, even when you clean and replace the filters, and no matter which setting your unit is on.

In some cases, this light will not even go off when you turn the air conditioner off, and this indicates that it is definitely an internal error, and it is not meant to be this way.

The first thing you should do when this light will not turn off is to remove the air filter from the AC and give it a good clean again. Once the filter is clean and dry, you can place it back into its holder and make sure that it is clipped in securely.

If the “clean filter” light still will not switch off after you have established that the filters are clean and secure, then there are a few troubleshooting solutions you can try, depending on the model of your air conditioner, such as:

  • Pressing the up and down temperature buttons simultaneously
  • Pressing and holding the “clean filter” button
  • Restarting the power to your LG air conditioner

After you have turned off this light successfully, it will switch on again in 250 hours to remind you to clean your filters.

Turning the “clean filter” light off with the temperature buttons

When you look at the “clean filter” light at the top of most LG air conditioner models, such as the LG 9,500 BTU DUAL Inverter Smart Window Air Conditioner and the LG 10,000 BTU Smart Window Air Conditioner, you will notice that the increase and decrease temperature control buttons are located just to the right of the light on the same control panel.

Once you have located these buttons, you need to press and hold the up and down button simultaneously for at least 30 seconds. This should cause the “clean filter” light to turn off.

Turning the “clean filter” light off by holding the clean filter button

Some LG air conditioner models do not have the same layout on their control panels, and cannot be reset using the temperature controls.

This includes models such as the LG LP0721WSR Portable Air Conditioner, which has a more modern and sleek design. On this unit, there will be a “Fan” or “Fan speed” button next to the “clean filter” light.

You will be able to reset the light by pressing and holding the “clean filter” button for 10 to 15 seconds. This will turn the “clean filter” light off until it comes on again at a later stage to remind you to clean your air filters.

Turning the “clean filter” light off by pressing the reset button on the power cord

If none of the above solutions turn the “clean filter” light off on your LG air conditioner, switching it off and back on again, essentially rebooting it, may help to restore proper functionality.

You can do this by pressing the bigger “Reset” button on the power cord of your air conditioner where it plugs into the power outlet.
