How to Reset Clean Filter Light on LG Air Conditioner: Quick Guide to Safely Reset Your Unit's Indicator Light

The “Clean Filter” light on your LG air conditioner is a helpful reminder to maintain optimal airflow and cooling efficiency by cleaning the air filter. However, after performing this maintenance, the light usually needs to be manually reset. If you’ve just cleaned or replaced your filter and the indicator is still on, follow these simple steps to reset the clean filter light:

1. Turn On the AC: Press the ‘Power’ button to ensure your air conditioner unit is running.
2. Locate the Filter Reset Button: On most LG air conditioners, the ‘Filter Reset’ button is found on the control panel, or sometimes it is activated through the remote control. For some models, it may be labeled “Filter,” “Clean Filter,” or have an indicator icon.
3. Press and Hold: Press and hold the ‘Filter Reset’ button for about 3–5 seconds. You should see the light turn off or the message clear from the display.
4. Check the Manual: For certain LG models, reset steps may vary; consult your specific user manual or LG’s support site if the light persists or if your model lacks a labeled reset button.

As an interior designer, I always emphasize the significance of regular filter maintenance—not just for technical reasons but also for maintaining indoor air quality and ensuring your home remains comfortable and healthy. Clean filters minimize dust buildup, optimize energy use, and ultimately extend the life of your unit. For clients managing multiple rooms or seeking efficient overall planning, integrating smart solutions such as a room planner can help schedule and manage home maintenance in harmony with the aesthetics and layouts of your living spaces.

Tips 1:

Remember to Clean Filters Regularly: Try setting a recurring reminder—every 2–4 weeks during peak usage or every month during off-peak times. A clean filter helps your AC perform optimally and contributes to a healthier indoor environment.
