You may not believe it is happening perhaps because you’ve been pretty regular in cleaning out your dryer lint trap. However, check the back of the dryer and you will see lint on the floor and floating around the vent pipe. The elements of a perfect fire is already there - high temperature, some oxygen and combustible fuel (in this case, lint).
The ironic thing about dryer vent fires is they can easily be prevented. Firefighters recommend that you do a yearly cleaning. It does not even take much time and money - it takes a little more than an hour to do and costs just $100 but it buys you a whole lot of peace of mind.
