Proper maintenance of your Clothes Dryer is important to your maintain the safety of your home. Along with cleaning the lint filter before every cycle, never put materials that have been used with solvents, oils or wax in dryers; never machine dry foam or rubber goods; check for blockages in vent pipes if drying cycles seem to be taking too long; replace ripped filters or cracked exhaust pipes, and make sure dryer vent flaps are not frozen shut in winter.
Never run the dryer when you are asleep, or not at home.
Install metal ducts rather than plastic ones that can bend, trapping lint. Having your dryer professionally cleaned every year is recommended.
