Barrington, IL has cold winters, so it is imperative to have a furnace that functions optimally. If your furnace is overheating, it cannot adequately regulate the temperature in your home, and it poses a safety hazard. Learn more about what can cause your furnace to overheat so you can fix the problem quickly to ensure your safety and comfort.

Airflow Restriction

If there is an airflow restriction, this can make your system work harder, which can eventually result in overheating. One of the most common causes is a clogged air filter. Blocked registers or vents can also impair airflow to a point where your system might overheat.

Heat Exchanger Issues

Overheating might occur if you have a cracked heat exchanger. Circulated air and combustion gases will mix if the exchanger is cracked. Not only can that crack damage your furnace, but it can also be dangerous for people and pets in your home because it can lead to carbon monoxide poisoning.

In some cases, the heat exchanger is too dirty. This can cause overheating due to the debris and dirt trapping heat. Regular maintenance can help prevent this issue.

Malfunctioning Blower Motor

The blower motor works to circulate air into your home. If it is faulty or worn, it must work harder than usual to do its job. The excess work can result in overheating.

Ignition Problems

A misaligned or faulty ignition system can result in the furnace working continuously. As a result, your furnace can overheat because it is not getting a break in between cycles.

If you notice that your furnace is overheating, it is important to get a professional to your home soon. They can diagnose the issue and provide a repair to get your system up and running and help prevent future issues.
