Open any windows and doors in the room where the dryer sits. A breeze can help keep the dryer cool during operation and help vent any fumes, such as carbon monoxide.
Install a dryer lint trap to catch the lint expelled in the dry cycle to prevent fabric particles from increasing household allergens.
Clean the internal lint screen and lint trap regularly. A buildup of lint is a fire hazard and reduces the effectiveness of the dryer. If your clothes are not drying in one cycle, check both areas for lint.
Run a vent hose from the dryer to a window or door leading to the outside. This doesn't need to be a permanent vent line but something you run with flexible aluminum vent hosing to send the heat, lint and fumes outside just when you are running the dry cycle.
