Cold air turns dryer lint into a wall inside the vent

Your dryer pushes out warm, damp air every load. Once that air hits the cold vent run, it cools fast, and the moisture in it gives the lint somewhere to stick instead of blowing outside. On a night near 19°F that happens within a few feet of the wall.

Layer by layer that buildup narrows the vent until air can barely get through. A blocked vent traps heat and moisture in the line behind your dryer, and that is where lint fires start.

How often should a dryer vent be cleaned?
Once a year is the general rule, but your household's laundry habits matter more than the calendar. A family running several loads a day builds up lint faster than one doing a load or two a week. If your dryer is taking longer to dry clothes than it used to, that's a sign to check the vent sooner rather than waiting for the year mark.
Can I clean my dryer vent myself?
You can clean the trap and the first few feet of duct behind the dryer yourself with a vent brush kit. What you can't reach is the rest of the run out to the wall or roof cap, especially where it bends or travels any real distance. A vent that's clogged further in is a job for someone with a rod long enough to reach the cap and a camera to check the work.
What are the signs of a clogged dryer vent?
Clothes that need more than one cycle to dry is the clearest sign. Others include the outside of the dryer feeling hot to the touch, a burnt smell during the cycle, and little airflow or lint coming from the outside vent hood when the dryer is running. If you notice more than one of these at once, the vent is worth checking before you run another load.
