As your furnace heats back up it is burning this dust off, hence the burning smell. This is normal and is not considered to be a safety hazard. The smell should go away after a few hours once the furnace burns all the dust away.

Will a furnace shut off if it overheats?

A common reason a furnace short cycles is because the heat exchanger, the part that heats your air, is getting too hot due to a lack of airflow. Once the heat exchanger overheats, it trips the high limit switch, which shuts the furnace down to protect it.

What causes a furnace to explode?

A furnace explosion is usually the result of ignition and instantaneous combustion of highly flammable gas, vapor, or dust that has accumulated in a boiler. The effect of the force from the explosion is often much greater than the boiler combustion chamber can withstand.

Can a furnace explode a house?

Gas Furnaces Can Explode With a gas furnace comes the risk that there could be a fire or an explosion if the gas leaks. This is exactly what happened to a home in Ontario; a gas explosion killed one man and damaged 40 other houses.

Do furnaces ever explode?

The need for this may arise if the furnace becomes too hot, or if there is some sort of electrical system interruption. To get the furnace working again, you simply press the reset button back down again.

How likely is a furnace fire?

The National Fire Protection Association says more than one in six home fires start from heating equipment, which is the second most common cause of a fire behind cooking. While most heating-related fires start from either space heaters or fire places, more than one out of every 10 starts with a central heating system.

What do you do after a furnace fire?

If your furnace catches fire, don't take chances. Immediately evacuate your home, and call 911.

Can an electric furnace cause a fire?

An electric furnace doesn't pose any danger of toxic gas leaks the way a natural gas furnace might. However, electric furnaces are powerful electronic devices and can potentially start fires.

Can a dirty furnace filter cause a fire?

When your furnace is working hard to pull air through, the dirty air filter could eventually get sucked back into the system. When this happens, air flow is compromised and you're at serious risk of a fire starting at the furnace level.

Is furnace a common cause of fire?

Is my furnace Safe?

If your furnace is burning a blue flame, very little CO is created and the unit is considered safe. The presence of a yellow or red flame indicates incomplete combustion and could mean dangerous levels of carbon monoxide are being produced.

What makes a furnace unsafe?

The cracked heat exchanger This is the most likely reason that a furnace may become unsafe. The heat exchanger is the metal compartment in the furnace where hot combustion gas collects. The hot metal walls of the exchanger are what warm the air that enters the living spaces.

How safe are gas furnaces?

The modern gas heater is built specifically to operate with minimal danger to people. The main concern with a gas heater is the leak of carbon monoxide, which is a toxic byproduct of the combustion of gas. Furnaces vent out CO through a flue, and there is very little chance that it will flow into the house.

Can a furnace catch fire?

Yes, a furnace can catch fire. The following are reasons your furnace can catch fire: Your furnace’s air filter is blocked. Your furnace’s gas pressure is too high.

Activate your furnace by replacing panels and covers carefully and setting your thermostat. Troubleshoot common issues that arise, like dirty filters and blown fuses.

Can a fan start a fire?

A fan can start a fire if the motor, switch or appliance cord fails. When any one of these fails, a part of the fan can heat up and drip hot plastic onto combustible materials. A cord or switch can also short-circuit and the fan itself can catch fire.

Are furnace flame rollouts A fire hazard?

According to FEMA, heating appliances were the second highest cause of residential building fires in 2014. One of the biggest culprits of these fires was furnace flame rollouts. (Yes, it’s as dangerous as it sounds.) Flame rollout happens when flames escape and “roll” outside of the closed combustion area.
