• Why Dryers Vent Has To Be Cleaned

As you know from cleaning out your lint filter, dryers produce very large quantities of lint. Most people assume their lint traps catch all the lint, however, a significant amount of this lint is not caught by the lint trap and builds up inside the dryer-even on the heating element and in other places inside the dryer, causing it to overheat and possibly catch fire.
As a rule, a fire starts from a spark in the machine. However, improper clothes dryer venting practices outside the dryer can play a key role in
this process.

Many fires can be prevented with proper dryer duct cleaning. In Canada
it is recommended that all North American style clothes dryers be
cleaned on the inside by a qualified appliance technician. The
Government of Ontario recommends that this service be done every 2 to 3 years as needed to remove lint from the rotating drum. The lint
will build in other areas also. It is also true that a loose wire could cause a spark inside the clothes dryer. The time frame for this service
would depend on many factors. The main factor is the style of dryer
ducting you have. If your dryer duct is not 4 inches round, the lint may
not flow as well as it should.

Poor dryer vent maintenance! Dryers vents are an often overlooked source of great potential danger because the highly flammable lint can easily ignite due to the combination of blocked airways and heat. That potential is magnified wherever there is restricted airflow or improper ventilation.”

A blocked clothes dryer vent caused the fire When a dryer is not venting properly it is less efficient and costs more to operate.

A plugged dryer vent will certainly cause a dryer to run hotter and increase the chance that something could catch fire. A dirty dryer vent, however, is only one link in a chain of events that must occur for a fire to start. Other events may include: failure of thermostat and limit switches in the dryer, lint inside the dryer, a missing or damaged lint screen, and a crushed hose behind the dryer.
