Key takeaways
- Lint burns easily
- A blocked vent lets heat build up
- Clean the lint screen after every load
- Do not run the dryer while you are out or asleep
Why lint matters
Lint is made of fine, dry fibers, and it ignites easily. When the vent is blocked, heat that should leave the house builds up around that lint.
Fire agencies list lint buildup and blocked vents among the leading causes of home dryer fires, which is why vent cleaning is such a common recommendation.
What raises the risk
Heavy lint in the duct, crushed or foil flexible duct, a very long run, a hot-running dryer and a damaged vent hood all raise the odds.
Gas dryers add another reason to keep the vent open: exhaust gases need a clear path outdoors.
Habits that help
Clean the lint screen after every load. Do not run the dryer when you are away or asleep. Keep the area around the dryer clear. Do not dry items that have been soaked in flammable substances.
Have the vent cleaned at least once a year, or sooner if you see warning signs.
Quick answers
Is it safe to use the dryer with a clogged vent?
It is better not to. If the vent is badly blocked or you smell burning, stop and have it cleared.
Do smoke alarms help?
Working smoke and carbon monoxide alarms near the laundry area are a good idea, but they do not replace a clean vent.
