Dryer airflow restrictions and vent-fire warning signs

Long drying times, excess heat, odors, weak airflow, and lint near the exterior flap can signal restricted venting and elevated fire risk. Cleaning the lint screen alone does not clear the full duct; persistent warning signs call for stopping use and arranging inspection or vent service. Recent local service content reiterates that vent restrictions can contribute to thermal-fuse failure but adds little actionable guidance.
