LG Flow Sense reports restricted exhaust airflow. Start by recording the exact model and what changed. A symptom alone cannot identify a failed part; these checks stay outside the appliance and within normal owner use.
Airflow and fire risk
Do not keep running a dryer with a severe or persistent blocked-vent indication.
What to check safely
- Stop using the dryer while a severe restriction remains
- Clean the lint filter and check the external vent outlet
- Have the duct inspected or cleaned if the warning persists
Stop if a step would require removing an electrical cover, bypassing a lock, opening a gas connection, or handling refrigerant. Your exact model manual controls the procedure.
Make the result useful
Record when the problem starts, whether an error message appears, and whether the safe checks changed anything. Compare that with the dryer troubleshooting section of your exact owner manual. If the symptom persists or a hazard is present, request qualified service.
