Keep the lint trap and outside vent clean in your clothes dryer. Some dryers have internal ductwork which may become clogged and require servicing, so if the dryer is operating poorly, have it checked. Lint or other material collecting near the heat coils in clothes dryers is extremely dangerous. Stay nearby while using the dryer. Have a smoke alarm and fire extinguisher nearby. If you must leave the area for a minute, turn off the dryer. After all, you are not going to be away long, and you can immediately turn the dryer on when you return.
