Why can't I adjust the fan speed on my LG ARNU48GTAB4 Air Conditioner?
- OoshawAug 6, 2025
You might not be able to adjust the fan speed on your LG Air Conditioner because it’s in Jet mode or Auto Operation mode. Some modes restrict fan speed adjustments. Also, the airflow may be automatically adjusted to prevent cool airflow during heating or to save energy during cooling. To solve this, select an operating mode that allows fan speed adjustments.
