Dryer vent maintenance isn’t just about drying performance — restricted airflow is one of the leading causes of home dryer fires nationally. Here’s how to stay ahead of it.
Clean the Lint Screen Every Load
This is the easiest and most important habit: remove visible lint from the screen before every single load, not just when it looks full. A thin film of lint that’s hard to see can still meaningfully restrict airflow.
Inspect the Exterior Vent Quarterly
Go outside and check that the exterior vent flap opens freely when the dryer is running. A flap that doesn’t open, or opens only partially, is a strong sign of a blockage further down the line.
Schedule a Full Vent Cleaning Annually
Lint accumulates inside the duct run itself over time, well beyond what the lint screen catches. We recommend a full vent cleaning at least once a year for most households — more often for longer vent runs or heavy laundry use. This is one of the most effective ways to prevent the E12 overheating error code from recurring.
Warning Signs Between Cleanings
Clothes taking longer than usual to dry, the outside of the dryer feeling unusually hot, or a burning smell are all signs you shouldn’t wait for the annual cleaning — book a dryer inspection right away.
Not Confident Doing This Yourself?
A factory-trained technician can diagnose and fix it safely, usually same-day.
