What is the condition of your dryer vent? A 2017 NFPA report states that annual dryer-cause fires average 14,630. Deaths: 9. Injuries: >420. Nearly $222 million in property damage. Leading cause: failure to clean vents and lint traps. nfpa.org/-/media/Files/…
Clean the lint trap every load - but also check your vent to the outside. Is it direct without a lot of bends? If it's >8 feet long, is it hard-piped? Is it clear from lint? Is it vented to an outside wall (preferably >10 feet away from any air intakes like HVAC equipment?
Think it can't happen to you? This is what I found in my dryer vent (after I had some technicians from an un-named big box hardware store in to replace it!). Yes that is a bird's nest. The technician said the vent didn't need to be replaced because there weren't any holes in it.
