Lint builds up in the machine over time and repeated drying cycles. Fortunately, the risk can be successfully minimized through regular maintenance and cleaning. Lint builds up, along with the temperature, and the result can be destructive. In addition to being combustible, lint also blocks up ventilation outlets, increasing humidity levels and decreasing drying capacity.

Also, too many people make the mistake of using their laundry room to store flammable materials, such as paint, paint thinner, or stain removers, all of which my ignite at high enough temperatures.
