If your dryer isn't acting like it used to, a clogged vent is the most likely culprit. Here's how to spot the warning signs early — before they become a safety problem.
Your dryer vent quietly fills with lint every single load. Over months, that buildup restricts airflow — making your dryer work harder, run hotter, and eventually become a fire risk. The good news: your dryer usually tells you when the vent needs cleaning. Watch for these seven signs.
This is the #1 sign. When the vent is blocked, hot, moist air can't escape, so your clothes come out warm but not dry — and you find yourself running a second cycle. If you're drying everything twice, your vent is almost certainly clogged.
Even if clothes eventually dry, a noticeable increase in dry time means restricted airflow. A healthy dryer finishes a normal load in roughly 30–45 minutes. If yours now takes 60–90, that's a red flag (and a higher energy bill).
When air can't flow out, heat builds up inside the dryer and the room. If the top of the dryer is hot to the touch or the laundry area feels like a sauna, the vent isn't venting.
A burning smell means lint may be overheating near the heating element — stop using the dryer and get it checked. A musty smell on freshly "dried" clothes points to trapped moisture from poor airflow.
Check the exterior vent flap while the dryer runs. Weak airflow, or lint collecting around the outside hood, means it's backing up. Excess lint around the lint trap area inside is another giveaway.
Many modern dryers have a safety sensor that shuts the unit down when it overheats. If yours keeps stopping partway through, it's protecting itself from a vent that's too restricted.
Even with no obvious symptoms, most homes should have the vent cleaned once a year. If you can't remember the last time — or you've never had it done — it's overdue. (See how often you should clean your dryer vent.)
You can do a quick check yourself: disconnect the dryer, look into the vent with a flashlight, and feel the airflow at the exterior hood while it runs. But a thorough cleaning means clearing the entire run — from the lint trap to the outside — which usually requires professional brushes and a vacuum.
