Let’s Count the Ways Your Furnace Can Fail on You


During our cold winters, the gas furnace becomes the most crucial appliance in your home, keeping it warm and comfortable. However, even the most reliable systems can encounter issues, and it’s crucial to be vigilant about identifying potential failures. In this guide, we’ll explore common problems that can plague gas furnaces and stress the importance of seeking professional help for repairs. Our team is experienced with handling furnace repair in Colorado Springs, and we’re ready to come to your assistance.

Common Furnace Problems

One: Pilot Light Issues

The pilot light is a small, continuously burning flame that ignites the main burner when the thermostat calls for heat. If you find your home colder than usual, the pilot light might be the culprit. Possible causes for its extinguishment include a faulty thermocouple, a clogged pilot orifice, or a malfunctioning gas valve. However, attempting to relight the pilot light yourself can be dangerous due to the involvement of natural gas. It’s crucial to call in professionals to address and fix these issues safely.

Two: Faulty Thermocouple

The flame sensor serves to ensure the safe operation of your furnace by detecting the presence of a flame. If your furnace exhibits issues such as frequent shutdowns or an inability to keep the main burner ignited, it may be a sign of a malfunctioning flame sensor. When the sensor fails to detect the flame, it signals the gas valve to shut off, preventing the release of gas into the burner. Always seek professional assistance for flame sensor-related issues, as they have the expertise to accurately diagnose and safely replace this critical component in your gas furnace.

Three: Ignition Problems

A gas furnace’s ignition system is responsible for lighting the burners. If your furnace is struggling to start, it might be due to ignition problems. Causes can range from a malfunctioning ignition control to a faulty pilot or igniter. Given the complexity and potential dangers associated with the ignition system, DIY repairs are strongly discouraged. Professional technicians have the expertise to diagnose and resolve ignition issues safely.

Four: Malfunctioning Blower Motor

The blower motor is responsible for circulating warm air throughout your home. If you notice reduced airflow, strange noises, or the complete absence of warm air, the blower motor could be the culprit. While it might be tempting to inspect or replace the blower motor yourself, it’s a task best left to professionals. They can accurately diagnose the issue, whether it’s a worn-out motor, a faulty belt, or other mechanical problems, ensuring your furnace operates efficiently.

Five: Clogged or Dirty Filters

Dirty or clogged air filters can significantly impact your furnace’s efficiency. Reduced airflow puts additional strain on the system, leading to overheating and potential component failures. While replacing air filters is a simple task homeowners can perform, it’s essential to schedule professional inspections regularly. Professionals can identify underlying issues, such as blocked ducts or a malfunctioning blower, which may contribute to filter problems.

It’s essential to recognize the limitations of DIY repairs when it comes to gas furnaces. Gas appliances involve inherent safety risks, and attempting to fix complex issues without the necessary expertise can lead to accidents or further damage.
