A gas stove flame is normally blue, so a yellow or orange flame can make you wonder whether the burner is working properly. You may notice the colour change on just one burner, while the others remain blue, or see yellow flames across several burners. Black marks appearing on the bottom of your cookware can also occur when the flame isn't burning as it should.
In this article, we'll explain what a gas stove yellow flame means, what can cause the flame to change colour, and what you should do if it doesn't return to normal.

Why Is Your Gas Stove Flame Turning Yellow or Orange?
Let's first look at why you may be seeing a gas stove yellow flame and what could be causing the colour change:
The Burner Holes Are Dirty
Grease, food spills, and small particles can collect around the burner holes. This can disturb the way the gas comes out and leave you with an uneven yellow flame instead of the usual blue one.
The Burner Cap Is Out of Position
The burner cap needs to sit properly on the burner base. Even a small shift after cleaning can affect the flame pattern. You may notice flames coming from one side, uneven flame height, or yellow tips.
The Burner Has Not Dried Completely
Water left around the burner after cleaning can temporarily affect the flame. This usually happens soon after washing the burner parts, with the flame settling once the moisture has dried.
The Burner Is Not Getting the Right Airflow
Gas needs to mix with the right amount of air before it burns. A problem around the burner's air intake can upset this balance and cause a yellow flame. This is more likely when cleaning the burner doesn't make any difference.
The Gas Supply Pressure Has Changed
A change in gas pressure can affect how the burner operates. You may notice the flame becoming weaker, higher, or changing colour, particularly when more than one burner is showing the same problem.
The Stove Was Converted or Connected Incorrectly
If the stove was recently installed, moved, converted for a different gas type, or connected to a new gas supply, the burner setup may not match the gas being used. The flame can change noticeably after such work.

What Can You Check When Your Gas Stove Flame Turns Yellow?
Now that you know what can cause a gas stove yellow flame, here are a few things you can check at home to get the flame back to normal:
Turn Off the Stove and Let the Burner Cool
Before removing anything, turn off the burner and wait until it is completely cool. This gives you a safe starting point for cleaning and checking the burner parts.
Remove and Clean the Burner Parts
Take off the burner cap and other removable burner parts as described in your stove's manual. Clean away grease and food deposits with a soft brush or cloth, then rinse the parts if the manufacturer allows it.
Clear the Burner Holes Carefully
Look at the small openings around the burner and remove any visible food particles or grease blocking them. Use a soft brush or the cleaning method recommended in your manual. Don't use a sharp pin or needle to enlarge the holes.
Dry Everything Before Reassembling
Let the cleaned burner parts dry completely before putting them back. Even a small amount of water around the burner can affect the flame when you switch it on.
Place the Burner Cap Back Correctly
Put the burner cap back in its proper position and make sure it sits flat. It should not wobble or sit at an angle when you gently touch it.
Clean Around the Burner Base
Wipe the area around the burner base with a damp cloth to remove grease and food residue. Keep water away from the gas openings and dry the area before using the stove again.
Try the Burner After Cleaning
Switch on the burner and watch the flame for a few seconds. Check whether it now burns evenly around the burner rather than appearing only on one side.
Check the Other Burners
Turn on the other burners one at a time and compare their flames. If only one burner has the problem, you can focus on that burner. If all of them show the same colour change, don't keep dismantling each burner at home.

When Should You Call a Professional?
By now, you know what can cause a gas stove yellow flame and what you can check at home. Here are some signs that your gas stove needs professional attention:
The Flame Stays Yellow on Every Burner
You have checked and cleaned the burners, but the same yellow or orange flame appears when you turn on each burner. When the colour change affects the whole stove, the issue may be with the gas or air supply rather than one burner.
The Flame Changes When Another Burner Is Turned On
One burner looks normal when used alone, but its flame becomes weak or changes colour when you turn on another burner. This isn't something you can correct by cleaning the burner parts.
The Flame Keeps Going Out on Its Own
The burner lights normally but goes out again while you're cooking, even when you haven't touched the knob. If you have to keep relighting the same burner, stop using it until the problem is dealt with.
Black Soot Keeps Returning to Your Cookware
You clean the black marks from your pots and pans, but they return after cooking. When this happens along with a yellow flame, the gas is not burning as it should.
The Flame Changed After a Gas Conversion
Your stove was recently converted for a different gas type or connected to a new gas supply, and you noticed the flame change afterwards. The burner setup may not match the gas being supplied, so this is not something to adjust yourself.
