How To Fix Orange Flame On Gas Furnace
When you see orange flames in your gas furnace, it can be alarming. After all, flames should be blue and not orange. While there are a few reasons why your gas furnace may be producing an orange flame, there are several steps you can take to address the issue. In this article, we’ll explain why your furnace may be producing an orange flame and how you can fix the problem.
What Causes an Orange Flame on a Gas Furnace?
The most common reason why your gas furnace may be producing an orange flame is due to a problem with the burner. Specifically, the issue is usually caused by a damaged, clogged, or dirty burner. This problem can be caused by poor maintenance, a dirty air filter, or a malfunctioning part. Additionally, a malfunctioning thermocouple can also cause an orange flame. The thermocouple monitors the temperature of the flame and sends a signal to the gas valve to keep it open. If the thermocouple is not working properly, the flame may burn too hot, resulting in an orange color.
Diagnosing the Problem
The first step in addressing an orange flame in your gas furnace is to identify the cause. If the issue is due to a dirty air filter, it’s a simple problem to fix. Just replace the air filter and the flame should be back to its normal blue color. If the issue is due to a malfunctioning part, such as the burner or thermocouple, you’ll need to call a professional to diagnose and repair the problem.
Fixing the Burner
If the issue is due to a clogged or dirty burner, you’ll need to clean the burner. To do this, first turn off the power to your furnace, then remove the burner cover. Carefully inspect the burner and any other components. If you see dirt or debris, use a soft brush and vacuum to clean the burner. Once the burner is cleaned, reassemble the parts, turn on the power, and test the furnace.
Replacing the Thermocouple
If the issue is due to a malfunctioning thermocouple, the part will need to be replaced. To do this, you’ll need to turn off the power to your furnace, then remove the thermocouple from the gas valve. You can then take the thermocouple to your local hardware store to find a replacement. Once you’ve replaced the thermocouple, reassemble the parts, turn on the power, and test the furnace.
Conclusion
An orange flame in your gas furnace can be a sign of a problem, but it doesn’t always mean there is an issue with the furnace. In most cases, the issue is due to a dirty air filter, clogged burner, or malfunctioning thermocouple. If you’re able to identify the cause of the orange flame, you can fix the problem yourself. However, if you’re not comfortable dealing with a gas furnace, it’s best to call a professional to help you diagnose and repair the issue.
