Clogged Dryer Vents Are A Fire Hazard — Mountain Man Fireplace & Chimney? ›

The worst the clogs get, the hotter the air the dryer produces; if allowed to continue, the superheated air can cause the extremely flammable lint to ignite and start a fire.

If your dryer vent is blocked, all of this built-up lint can become a fire hazard. The heat from your dryer could cause the lint to combust, potentially catching your dryer and parts of your home on fire.

A clog in your vent prevents the hot, moist air from escaping your dryer, which prolongs the drying time and leaves your clothes wet at the end of a cycle. 2. You notice a burning smell. Lint and fabric fuzz are highly flammable, so it doesn't take too much heat to ignite a small piece.

Every year, firefighters across the country respond to around 13,820 home fires caused by clothes dryers, according to the latest figures from the National Fire Protection Association. About 27 percent of these fires are caused by an accumulation of lint, which can constrict the ductwork that expels hot air outside.

The most common cause of dryer fires is the result of lint build-up in the dryer and exhaust duct. When dryers are not cleaned on a regular basis the lint build-up restricts airflow, and when the airflow is restricted, clothes take longer to dry. This is the first indication that there is a problem.

When vents are obstructed, heat can build up in the ductwork, increasing the risk of a fire. Additionally, if flammable materials are placed near blocked vents, the chances of a fire spreading rapidly are heightened. It is crucial to keep your vents clear of any obstructions to minimize the risk of fire accidents.

The dryer vent that leads from the appliance to the outdoors gets clogged with time and consequently produces a fire hazard. A clogged dryer vent can be caused by a buildup of lint in the ventilation system, or by items from your pockets like gum wrappers or coins.

It is not effective when your vent has a lot of curves or has a concertina-style pipe because the lint might get stuck to the curves. But if your dryer vent is short and straight, you can safely use a leaf blower for dryer vent cleaning.

Overheat Shutoff

If your dryer is getting too hot due to trapped heat and moisture because of a log or blockage in the vent line, the machine may turn off mid-cycle. This fail-safe is the dryer manufacturer's final effort to prevent a dryer fire, and should be taken as a sign that immediate service is needed.

What is the number one cause of house fires? ›

1. Cooking. Unattended cooking is listed as the number one cause of residential fires.

In back of most dryer units is a short 4-inch diameter exhaust. This exhaust connects to dedicated ductwork inside the wall through an aluminum elbow or other pipe. Hot air travels along these metal pipes to eventually emerge through an opening on an outside wall of your house.

Most dryers and vent systems require cleaning every one to three years in order to maintain optimum efficiency and the highest level of safety. But how often your dryer vents need cleaning also depends on: Volume of laundry dried weekly. The total length of your dryer vent system.

Carbon monoxide is not produced by electric dryers. In general, electric appliances cannot produce carbon monoxide unless they are on fire or some other kind of combustion is going on. If you have carbon monoxide in your home, the source is likely a gas appliance (and you should evacuate and call the authorities.)

Clear out combustibles. Move any flammables like cleaning supplies far away from your dryer. Also regularly sweep out dust in the areas around and underneath your dryer. Opt for a solid metal dryer duct.

Overheat Shutoff

If your dryer is getting too hot due to trapped heat and moisture because of a log or blockage in the vent line, the machine may turn off mid-cycle. This fail-safe is the dryer manufacturer's final effort to prevent a dryer fire, and should be taken as a sign that immediate service is needed.

Many homeowners do not know that carbon monoxide is vented through your dryer's vent. The fumes that a gas dryer emits are dangerous. If these fumes are not able to escape through the vent, carbon monoxide will enter your house. Carbon monoxide poisoning is deadly.

It's not complicated. For most dryers, it's a case of removing the lint trap from an easily accessible slot, scraping the fluff off the mesh, and sliding the filter back in. Clean the vent duct behind your dryer using a vacuum cleaner hose.

One of the most obvious signs of a clogged dryer vent is a burning smell coming from the dryer. This smell is often caused by the lint trap and debris that has built-up in the vent catching fire.
