A furnace that doesn’t work properly can inconvenience you in your Buford, GA, home, especially during winter. Here are some of the most common reasons your furnace is overheating.
Lack of Proper Airflow
If your furnace’s air filter is dirty, this can reduce its ability to cycle warm air through the system. This causes the air to build up which can lead to overheating. To prevent this, be sure to regularly clean or change the air filter to maintain proper airflow.
Broken Thermostat
A malfunctioning thermostat is another common cause of overheating. If a thermostat can no longer send the appropriate signals, your furnace may cycle at the incorrect time or continue to run long after the temperature change. If your thermostat is over 10 years old, it may be a good time for a replacement.
Old Blower Motor
The blower motor helps move heated air through the vents and once it becomes worn out, the furnace may begin to overheat. The blower motor requires routine maintenance to function well. If you haven’t scheduled maintenance in a long time, be sure to arrange an inspection as soon as possible.
Malfunctioning Limit Switch
The limit switch signals the furnace to turn off if there is too much heat. If something goes wrong with the limit switch, the furnace will not regulate its temperature properly and heat levels can increase. In some cases, there may be too much dust as well, which can also cause the limit switch to malfunction.
Short Cycling
Short cycling will cause your furnace to shut off before it can circulate hot air properly. This may cause heat to build up because air is not flowing as it should be. It can also damage the furnace’s components due to the excessive heat, which can lead to repairs.
Overheating furnaces are not an uncommon HVAC problem, but you should request assistance from a licensed professional to make sure all the components are functioning properly. Contact Pruitt Heating & Air, Inc. today to schedule our furnace repair services in Buford, GA.
