Why Is My Gas Stove Flame Orange?


In this article…

Having a gas appliance may pay special attention to its repair and maintenance. Fix Appliances CA has knowledgeable and skillful gas fitters who can solve any problems with your gas stove. Upon our experience, our experts always receive a question: why is my gas stove flame orange, red or yellow, and what does it mean?

You might know that the flames of a perfectly safe and normal gas stove are blue-coloured. And this blue colour of the gas stove flame means that your gas stove is working properly and the appropriate amount of carbon monoxide is being released.

What Does an Orange Flame On the Gas Stove Mean?

The flames from a gas stove using natural gas need attention and care as any other colour can clue on to a possible hazard. The burners may need cleaning or adjusting if you see orange, yellow or red flames instead of blue flames. The orange colour warns you that the gas stove has inappropriate combustion and may emit treacherous carbon monoxide gas (CO) levels.

The orange flame is a symptom of excessive carbon monoxide, the so-called silent killer:

  • Extremely lethal for the human body, it can lead to symptoms like headaches, light-headedness, nausea, and dizziness.
  • Responsible for damaging your utensils – it turns your new and shiny utensils black. Thus, it is hard or impossible to clean to its initial view. Moreover, it can reduce the overall strength of the utensil.
  • Third, it is a sign that your stove is not working properly and needs professional gas fitters’ immediate attention and gas appliance repair.

Orange Flame carbon monoxide poisoning

A yellow flame may be a sign that the burner is not obtaining enough air for the complete combustion of the gas. And in this case, this problem includes adjusting the burner’s air shutter to admit more air.

Why is a Gas Stove Flame Orange?

An orange flame indicates the presence of carbon monoxide resulting from incomplete combustion. It can cause problems related to food, utensils, and human health. Some of the main reasons for an orange flame can be the following:

  • Extra humidity in the air
  • The gas stove is getting clogged due to excessive soot
  • Insufficient amount of oxygen

The normal flame is blue, but if you notice a yellowish-orange flame on the stove, it is a sign of disorder. Burning an orange flame means releasing a large amount of carbon monoxide.

The other thing is that the orifices are clogged for some reason, and sometimes, proper combustion doesn’t occur, resulting in orange flames. Thus, fixing the appliance immediately to prevent any problem is a high priority.

If the flame of the gas stove is burning orange, it means that the gas stove is to be fixed immediately as it is not working properly.

How to Fix the Orange Flame on a Gas Stove?

Whenever you see a problem with the colour change of the flame, you should fix it as soon as possible. Having faced this problem more often, we must admit the following factors on why orange flame may appear on your gas stove and how to fix this problem:

  1. Humidity Level:
    Humidifiers are necessary but also change the flame colour from blue to orange. If your humidifier is turned on near any stove, turn it off and see whether that makes a difference.
  2. Proper Orifices:
    Make sure you use the proper orifices depending on your range (whether you are using natural gas or propane). Along with this adjustment, ensure that the gas pressure regulator valve was changed and the brass orifice was adjusted.
  3. Clean Burners:
    Ensure that the gas-burning orifices on the stove are clean and free from any kind of waste. You have to clean the stove well, so no clogged soot is left in the igniter or the holes. Make certain that all portholes and burners are free of debris. Cooking grease on any spillovers may block these openings and, in turn, affect the colour of the flame.
    NB: After cleaning, ensure that you put them in the same position, which can also influence the flame colour.
  4.  Air Fuel Ratio:
    Another problem that may cause the flame to turn orange is the fuel-to-air ratio. When your burner is not getting enough air, there is no complete combustion of gas. If this is the case, adjust the burner’s air shutter to admit more air.

Is an Orange, Red or Yellow Flame On a Gas Stove Dangerous?

Orange, red or yellow flames can be very serious and harmful as it is formed due to improper gas stove work. The carbon monoxide (CO) released is poisonous and can cause severe health problems. Carbon monoxide is not a noticeable gas, so we do not even notice that we are inhaling it until it’s too late.

Moreover, when the appliance is not working properly, it can cause an explosion.
It is advised to deal with the gas stove properly. One should be very careful while using the gas stove. Whenever you find a tiny difference in the colour of the flame, repair it before working on it to prevent substantial consequences.

You shouldn’t worry as long as the stove flame is blue, but whenever it turns orange, you should repair it as soon as possible to avoid any hazards.
