If you've seen a Flow Sense warning on your LG dryer, you're probably asking yourself: how do I clear the Flow Sense on my LG dryer? The good news is that this alert usually means your dryer is trying to protect itself from poor airflow. According to 2026 updated appliance maintenance recommendations, restricted airflow is one of the leading causes of longer drying times and reduced efficiency.

Why Does the Flow Sense Warning Appear?

LG's Flow Sense feature monitors the airflow moving through the dryer and vent system. When it detects a blockage, it displays a warning to help prevent overheating. In most cases, the issue is caused by lint buildup, a clogged vent, a crushed dryer hose, or an exterior vent flap that isn't opening properly. As highlighted in 2026 updated dryer care guidelines, even a small blockage can affect performance.

How to Clear the Flow Sense Alert

Start by cleaning the lint filter and checking the vent hose behind the dryer. Disconnect the vent if necessary and remove any lint or debris. Next, inspect the outdoor vent opening and make sure air can flow freely. After cleaning, run a short drying cycle. Once proper airflow is restored, the Flow Sense warning often clears on its own without requiring a reset.

How to Keep the Warning from Coming Back

Regular maintenance is the easiest way to prevent future Flow Sense alerts. Clean the lint filter after every load and have your dryer vent professionally cleaned at least once a year. Based on 2026 updated appliance service recommendations, routine vent maintenance improves drying performance, lowers energy consumption, and helps extend the life of your dryer.
