A gas stove is a commonly used kitchen appliance that relies on gas as its primary fuel source. The flame on a gas stove is typically blue, indicating that the fuel mixture is properly balanced. However, at times, you may notice that the flame is green. This can be a cause for concern as it may suggest an issue with your gas stove. In this blog, we will explore the phenomenon of the green flame on gas stoves, its causes, and whether it is safe to continue cooking on a stove with a green flame. We will also discuss some possible solutions for fixing the issue.

What Does Green Flame On Gas Stoves Mean?

A green flame on a gas stove is not a common occurrence. When a gas stove is functioning properly, the flame should be blue. A green flame typically indicates that there is an issue with the gas stove that needs to be addressed. The green flame is usually accompanied by a hissing sound and a strong odor of gas. If you notice these symptoms, it is crucial to take immediate action to address the issue.

What Causes A Green Flame?

There are several reasons why a gas stove might produce a green flame. The most common causes are discussed below:

The Fuel Mixture Is Too Rich

The fuel mixture in a gas stove needs to be carefully balanced. If there is too much gas in the mixture, the flame will turn green. This is because the excess gas is not being completely burned off, resulting in incomplete combustion. This can also cause the flame to flicker and produce a hissing sound.

Liquid Cleaning Fluid Left In The System

If you recently cleaned your gas stove with a liquid cleaning fluid, some of the cleaning fluid may have made its way into the gas lines. This can lead to a green flame as the cleaning fluid does not combust properly.

Copper Combustion

If the gas stove has copper components, such as copper tubing or copper burner caps, the copper can combust and produce a green flame. This is because the copper reacts with the gas and produces a green flame.

Is It Safe To Cook On A Gas Stove With A Green Flame?

Cooking on a gas stove with a green flame is not recommended. A green flame can be a sign of incomplete combustion, which can lead to the release of toxic gases, such as carbon monoxide. In addition, a green flame can cause food to cook unevenly, as the heat distribution may be affected. It is crucial to address the issue as soon as possible to ensure the safety of your home and family.

How To Fix Green Flame On Gas Stove?

If you notice a green flame on your gas stove, there are a few steps you can take to fix the issue. These include:

Check the fuel mixture:

If the fuel mixture is too rich, adjust the air shutter on the burner to allow more air into the mixture. This will help to balance the fuel mixture and produce a blue flame.

Clean the gas lines:

If you recently cleaned your gas stove with a liquid cleaning fluid, it may have made its way into the gas lines. To fix this, turn off the gas supply and disconnect the gas line from the stove. Use a clean cloth to remove any excess liquid from the gas line before reconnecting it to the stove.

Replace copper components:

If the green flame is caused by copper combustion, consider replacing any copper components in the gas stove with non-copper components. This will prevent the copper from reacting with the gas and producing a green flame.


In conclusion, a green flame on a gas stove is not normal and indicates an issue with the stove. It is important to take immediate action to address the issue to ensure the safety of your home and family.
