In this short guide, we are going to answer the question “ how to fix an orange flame on the gas stove?” with an in-depth analysis of the gas stove. Moreover, we will discuss the causes of fuel oxygen mixture imbalance.

How to fix the orange flame on the gas stove?

Don’t be worried by the orange flame just yet; it isn’t a hazard in and of itself and will only become a threat if not corrected. Here’s how to repair an orange flame.

Clean Burners

Soot builds up and covers the small holes in the gas stove burner as a result of incomplete combustion, necessitating thorough cleaning. Make sure to thoroughly clean the entire gas burner, taking care not to leave clogging in the holes or the igniter.

To remove any trash or food particles, thoroughly clean the burners. Cooking spills, such as oil, milk, and other food remnants, burn on the gas stove burner, producing a yellow color inside the otherwise blue flame.

Cleaning and maintenance require tampering with the components of the gas stove, so remember to return every little piece to its proper location because incorrect component placement might change the color of the flame.

Proper Orifices

Natural fuels do not require the same air-to-fuel ratio as conventional fuels. Because liquid propane requires more air to burn than natural gas, be sure your burner has orifices designed for natural gas. Also, alter the valve that controls gas pressure and adjust the brass aperture.

More air, please

Due to an imbalanced air-to-fuel ratio, which is most likely caused by poor ventilation, the flame on the gas stove burner may change from blue to yellow. Due to competition for oxygen between the stove and people, poor airflow in the kitchen can limit the quantity of air available to the stove, resulting in incomplete combustion and the risk of suffocation. It is preferable if all air inlets, such as doors and windows, are opened. Place the air shutter to allow sufficient airflow if the problem is with the burner.


Humidity is beneficial to your health since it keeps your skin shining and reduces the symptoms of sinus infections. However, using a humidifier with a natural gas stove is not recommended since it interferes with optimal combustion, resulting in yellow flames. If you have a humidifier in the room where the gas stove burner is located, such as the kitchen, turn it off until you are ready to use the stove.

Is orange flame dangerous for your health?

When there is insufficient oxygen flow to the fuel, the gas burner produces orange flames. The presence of orange flames on the gas stove indicates a high level of carbon monoxide in the surroundings.

Carbon monoxide is a toxic gas that is harmful to human health. Carbon monoxide displaces oxygen in the blood and deprives the heart, brain, and other essential organs of oxygen when inhaled inadvertently. If there is a high concentration of carbon monoxide in the area where you are breathing, it will overpower you without warning within a few minutes and you will lose consciousness.

Dismantling and reassembling

This strategy has shown to be effective in the past, so it’s worth a shot. Begin by removing the top grate and lifting the top of the stove to gain access to the burner pipework. The air shutters, which are normally a plated or tube covering the burner’s air vent, are usually found behind the gas valves. To loosen the shutter, use a screwdriver. Light the burner and gradually adjust the air shutters until a full blue flame appears. Finally, tighten the screws and replace the stovetop and top grates after turning off the burner.

Causes of Fuel-Oxygen Mixture Imbalance

The orange flame on your gas stove is caused by a variety of factors of faulty combustion.

Burner Orifices Clogged

To grasp this concept, keep in mind that incomplete combustion produces soot that adheres to the burner orifices and any other surfaces. Soot cakes continue to accumulate in the orifices of gas stove burners, obstructing the appropriate air passage. Burning soot gives forth a brilliant orange glow.

Furthermore, some of the gas is blocked by the soot, resulting in air pockets and cooler orange flames. As a result, only a small percentage of natural gas is burned to produce the intense flame, while the rest is wasted. Gas waste can add a significant amount to your monthly rates.

Increased Humidity

Increased humidity can cause the gas stove’s flame to become yellow, especially if the burner is in the same room as a humidifier.

Wrong Orifices

For complete combustion to occur, carbon fuels used in gas stoves have varying air and fuel mixture ratios. Natural gas, for example, will require a different amount of air than liquid propane. If you have a new burner and notice an orange flame, it signifies that either the manufacturer placed the air shutter incorrectly or the burner you purchased is incompatible with your gas stove.

Food spillage

When food and drink are left unattended, they may flow over the pot and onto the burner. You’ve all experienced milk pouring when you least expect it! Food particles burning on your gas stove burner may produce a brilliant yellow flame.
