Clogged or partially clogged dryer vents can also result in increased operating costs with longer drying times. This will also cause premature failure of components or the dryer.In a recent independent study it was found that a load of 7 large bath towels in a dryer with 62.5% vent restriction took 60% more time to dry the same size load and used 77% more energy than the load without the restricted vent.
The following are steps the Consumer Product Safety Commission recommends Homeowners should take to prevent dryer vent fires.
- Clean the Lint screen/filter before or after drying each load of clothes. If clothing is still damp when removed after a normal dryer cycle or requires a much longer than normal dryer cycle, this may be a sign the dryer vent needs cleaning.
- Clean the dryer vent and exhaust duct (hose connected to the dryer) periodically. While the Consumer Product Safety Commission gives no recommendation as to cleaning frequency, most manufacturers recommend annual cleaning for the dryer to work at maximum efficiency.
- Check and clean the outside dryer vent exhaust for obstructions and make sure the flapper opens and closes properly. If the flapper is not fully closing, birds and rodents can nest in the dryer vent line.
- Clean behind and around the dryer where lint can build up. Keep the area around the dryer clean and free of lint and clutter.
- Replace old style flexible plastic/vinyl hose with corrugated or foil hose. The plastic/vinyl hose is no longer allowed in most states and is not fireproof and can actually cause a fire to start and spread quicker.
- The interior of the dryer chassis should be cleaned by a qualified service person periodically. Lint and debris will build up inside the dryer as well as in the dryer duct.
