I see a lot of dryers getting new thermal fuses when the real issue is airflow. Am I off base?

My old Kenmore has blown two thermal fuses in ten years, both times from a bad heating element.

Yeah that thing about airflow is spot on. My buddy was replacing thermal fuses like crazy on his dryer, new one would last a month then pop again. Turns out his exhaust vent going outside was almost completely packed with lint, like a solid tube of it. He cleaned that out and the dryer has been fine for over a year now, no more blown fuses.

Wow, I ran into that exact issue last winter. My dryer was overheating because the outside vent flap was frozen shut with ice. Once I cleared the ice, the dryer stopped blowing fuses and worked perfectly.

That "solid tube of lint" description is alarming. How often should homeowners be checking their dryer vents to prevent this?
