A clogged dryer vent may quickly turn into a serious problem, When was the last time you had your dryer vent cleaned? Therefore, it is very important to perform proper maintenance and observe certain events that can predict a blockage. This can save you money… or save lives.

How dryer vents work and why they are necessary

Knowing how they work can help you detect malfunctions and prevent breakdowns or more serious safety problems.

Clothes dryers work by spinning wet clothes through hot air in a rotating drum. This hot air evaporates the moisture, collects it and, with a fan, pushes it out of the dryer.

The vent then carries this moist air from the dryer to the outside of the house. At the back of each dryer is a 4-inch diameter metal vent that exhausts the water-laden air.

With most dryers, this air cannot be blown into the house. The air is moved from the dryer to the outside with a flexible, semi-rigid or rigid tube. One end of this tubing is connected to the dryer and the other to a hole cut in the side of the house.

The vent must be free of obstructions for safety reasons and for proper drying performance. The following signs may indicate that the dryer vent is obstructed.

The Warning Signs and Dangers of Clogged Dryer Vents

Check for water leaks

If moist air is not being drawn out of the appliance, there may be puddles around and behind the dryer or inside the vent. If you find puddles around the appliance or vent, check the vent to see if it is clogged or blocked.

Check for lint or fibers in the lint filter
