An overheating furnace could cause serious risks to your Brunswick, GA home’s comfort and safety. It’s important for you to know what can cause this issue so that you can keep an eye on your heating system. Let’s discuss the causes of furnace overheating and how to identify them in your home.

1. Dirty Air Filter

Airflow restrictions can occur when your air filter clogs with dirt and debris. As a result, your furnace will have to work harder to circulate air. Different components, such as the heat exchanger, can overheat as a result.

2. Blocked Registers or Vents

Closed and blocked registers and vents restrict the amount of air flowing into the rooms of your home, causing an imbalance inside your furnace. Overheating can occur because your furnace will struggle to maintain the right temperature and adequate airflow.

3. Blocked or Dirty Heat Exchanger

Dust, debris and dirt can accumulate inside your furnace’s heat exchanger, negatively affecting airflow and heat transfer. It can develop a combustion gas buildup, which can cause a safety issue.

4. Malfunctioning Blower Motor

Inadequate airflow can result when your blower motor isn’t working properly, resulting in overheating. Motor failure, worn bearings and electrical issues can cause this problem.

5. Electrical Problems

Electrical issues can lead to furnace overheating and pose a fire hazard. The problems might include faulty wiring, loose connections or tripped breakers. If you suspect an electrical issue, you must turn off your heating system and call a professional right away.
