When your furnace in your Miles, TX home overheats, you have a serious problem. Overheating can lead to costly repairs and even safety hazards. Here are five common causes of furnace overheating and what you can do about them.
1. Blocked Air Filters
Clogged air filters cause overheating by restricting airflow. Filters trap dust and other debris to keep indoor air clean. When dust and debris build up, they block airflow, forcing the heating system to run longer and heat up more than normal.
Change the filters every one to three months to prevent this issue. Keeping them clean allows air to flow freely and reduces strain on your furnace.
2. Blower Motor Problems
The blower motor in your furnace pushes warm air into your home. If it isn’t working correctly, the blower motor traps heat inside it. Trapped hot air causes the heating system to overheat.
You may notice your furnace cycling on and off frequently, which signals that the motor needs attention. Have a technician inspect and repair the motor to keep your heating system running smoothly.
3. Blocked Vents or Registers
Blocked vents prevent warm air from circulating properly. When furniture or other items cover the vents, your furnace has to work harder to push air through.
This extra effort can lead to overheating, especially if there are several blocked vents. Make sure all vents and registers are open and free of obstructions.
4. Thermostat Issues
A malfunctioning thermostat can cause your heating system to overheat. If it doesn’t read the temperature correctly, it may run longer than needed, which overheats the it. Replacing an old or faulty thermostat with a new unit can solve this problem.
5. Dirty Burners
Dirty burners can cause the furnace to overheat. When dust and dirt build up on the burners, they prevent proper ignition, leading to inefficient combustion and increased heat inside the system.
Cleaning the burners helps the heating system run more efficiently. Regular maintenance by a professional can prevent buildup and keep your furnace from overheating.
