Gas stoves are a common and popular cooking appliance in many households. They are efficient and easy to use, making them a favorite among home cooks. However, when you turn on your gas stove and see a red flame, it can be a cause for concern. In this blog, we will discuss what a red flame in gas stoves indicates, the causes of a red flame, and how to prevent it.

What Does Red Flame In Gas Stoves Indicate?

A gas stove flame should be blue. A blue flame indicates that the gas stove is burning the gas efficiently. A red flame, on the other hand, indicates that the gas stove is not burning the gas properly. It may also indicate that there is a problem with the gas stove. If you notice a red flame on your gas stove, it’s essential to address the issue promptly to prevent any potential safety hazards.

What Causes A Red Flame?


There are several reasons why a gas stove may produce a red flame. One of the most common causes is dirt and debris build-up on the gas stove’s burner. Over time, grease and food particles can accumulate on the burner, which can cause a red flame. Another cause of a red flame is an improper air-to-gas ratio. When there is too little air or too much gas, the flame can turn red.

Other possible causes of a red flame include:

  • A gas valve that is partially closed or restricted.
  • A clogged gas supply line or valve.
  • A gas stove that has not been properly installed or adjusted.
  • A damaged burner or igniter.

Should You Use A Gas Stove With A Red Flame?

No, you should not use a gas stove with a red flame. A red flame can be a warning sign of a gas stove malfunction, which can be dangerous. If you continue to use a gas stove with a red flame, it can increase the risk of fire or carbon monoxide poisoning.

How To Reduce Red Flame In Gas Stoves?

Clean The Gas Stove

One of the most common causes of a red flame is a dirty gas stove. You can clean the gas stove’s burners by removing them and wiping them down with a clean cloth. Be sure to remove any dirt or debris that has accumulated on the burner. You can also use a toothbrush to clean any hard-to-reach areas. Once the burners are clean, you can replace them and turn on the gas stove to see if the flame is blue.

Readjust The Air Shutter

The air shutter controls the air-to-gas ratio, which can affect the color of the flame. If the air shutter is not properly adjusted, it can cause the flame to turn red. To adjust the air shutter, turn off the gas stove and remove the burner. Locate the air shutter and adjust it until the flame turns blue. Once you have adjusted the air shutter, replace the burner and turn on the gas stove to see if the flame is blue.

Professional Servicing

If cleaning the gas stove and adjusting the air shutter do not solve the problem, it may be time to call in a professional. A professional gas stove technician can inspect your gas stove and diagnose the problem. They can also perform any necessary repairs or adjustments to ensure that your gas stove is safe to use.

Bottom Line

A red flame on a gas stove is not normal and can be a warning sign of a potential safety hazard. If you notice a red flame on your gas stove, it’s essential to address the issue promptly. You can reduce the red flame on your gas stove by cleaning the burner, adjusting the air shutter, or calling in a professional technician. By taking the necessary precautions, you can keep your gas stove running safely and efficiently.
