If your dryer is still producing heat but taking longer to dry a load of clothes, the exhaust duct may be clogged with lint, birds' nests and/or other debris. It's hard on the dryer, frustrating for you, and - in the case of a gas-fueled dryer - possibly life threatening.
Lint and flue gases use the same avenue of exit from the house. A blocked vent can cause poisonous carbon monoxide (CO) fumes to back up into the house. These fumes are odorless and colorless and they can be fatal! CO poisoning symptoms mimic those of flu (without the fever): headache, weakness, nausea, disorientation and deep fatigue. You can fall asleep, lapse into a coma, and die.
If you have an electric clothes dryer, you need not worry about carbon monoxide, but a plugged-up exhaust duct is still bad news! With both types of dryers, heat that builds up and cannot escape presents a safety hazard. Clothes dryers do catch on fire.
Most dryer fires start beneath the dryer when the motor overheats due to this buildup of lint. The draft from the dryer will pull the fire up into the venting system and, in many cases, cause a house fire. Click below to learn more...
