In the world of furnace maintenance, the color of your pilot light flame can be a major indicator of your system’s health. A properly functioning furnace typically has a blue pilot light flame, which signifies efficient and safe operation. However, if you notice that the flame is any color other than blue, particularly yellow or orange, it is time to pay attention. This change in color is not just a random occurrence, it could be a warning sign of underlying issues. New York Air Conditioning, Heating & Plumbing would like to highlight why a pilot light flame might change color and what it means for your furnace.
Should Furnace Flame Be All Blue?
The blue color of a pilot light flame is due to the complete combustion of the gas. This complete combustion ensures that the furnace is operating efficiently and safely. The blue flame is achieved when the gas-to-air ratio is correct, allowing for the efficient use of fuel with minimal waste and emissions.
What Causes Yellow or Orange Flame on Furnace?
A yellow or orange pilot light flame is often a cause for concern. This color change can indicate several potential issues:
• Inefficient Combustion: A yellow or orange flame suggests incomplete combustion. This means that the gas is not being burned efficiently, leading to higher fuel consumption and increased costs.
• Presence of Contaminants: Sometimes, the change in color can be due to the presence of contaminants in the gas. Dust, rust, or other debris can alter the combustion process.
• Carbon Monoxide Risks: The most serious concern with an inefficiently burning flame is the potential for carbon monoxide production. Incomplete combustion can lead to this dangerous gas being emitted into your home.
• Ventilation Issues: An improper air-to-gas ratio can cause the flame to burn yellow or orange. This might be due to issues with the furnace’s ventilation system or adjustments needed in the burner.
How Do You Fix a Yellow or Orange Flame in a Furnace?
If you notice that your furnace’s pilot light is not burning blue, it’s important to take immediate action:
• Safety First: If you suspect carbon monoxide is present such as signs that include headaches, dizziness, nausea, or other flu-like symptoms, evacuate the house and call emergency services.
• Furnace Inspection: Turn off the furnace and call a certified HVAC technician to inspect it. They can clean the pilot light orifice and adjust the gas-to-air ratio.
• Regular Maintenance: Regular servicing of your furnace can prevent issues with the pilot light. Technicians can clean and adjust the components to ensure efficient operation.
• Install Carbon Monoxide Detectors: As a precautionary measure, install carbon monoxide detectors in your home to alert you of any dangerous gas levels.
