Furnaces are manufactured with a number of safety controls that make them very safe to operate. However, allowing a malfunctioning furnace to continue operating can create dangerous situations that can’t be remedied by safety switches alone. Depending on the type of furnace you have, different scenarios can develop that may potentially compromise the safety of your family and your home. Making needed repairs to your furnace as soon as possible allows your furnace to run not just optimally, but safely. Following are some reasons why waiting to make repairs to your furnace can be a potentially dangerous situation.
Electric furnaces do not generate combustion byproducts, but this doesn’t mean that certain risks can’t develop when issues with your electric furnace aren’t remedied. One of the more common problems that can develop with an electric furnace is an issue with the system’s circuit breaker. Electric furnaces draw enough power to warrant having their own circuit breaker in your home’s electrical box. If the breaker trips, this usually indicates that the furnace is drawing too much power and as a safety precaution, the breaker turns off. You can try to turn the breaker back on, but should you encounter resistance or the breaker trips again, don’t keep resetting it; instead, call for repair.
Combustion furnaces generate toxic fumes and gases, the most noteworthy being carbon monoxide. The heat exchanger is responsible for separating these toxic byproducts and venting them safely to the outside via the flue. However, should the heat exchanger or the flue develop cracks or serious corrosion, these fumes and gases can escape and circulate into your living spaces.
There are also a number of safety switches that cut off the fuel supply should unsafe conditions develop. Limit switches, flame sensors and thermocouples are all examples of safety mechanisms that are installed into your furnace to ensure that fuel supply is both monitored and managed. Operating your furnace knowing that certain safety switches and mechanisms aren’t working properly can put you, your home and your system at risk.
