How to Fix Yellow Flame on Gas Stove

Several different things could cause a yellow flame on a gas stove. For example, the flue may have been dirty, or the pilot light may have gone out, which will need to be fixed so your stove can operate adequately. But if you are looking for quick fixes that you can do yourself at home, read below! 

How to Fix Yellow Flame on Gas Stove

The first thing you should do is check the exhaust pipe to see if it’s clogged with debris. Then turn off the valve and open up all of the windows in your house to let fresh air come through.

If these steps don’t work, try cleaning your burner head and chimney with a wire brush and lighter fluid; this should solve any problems with those parts of the stove and allow for a clean and efficient burn. This blog post will show you how to fix yellow flame on gas stove.

Step by Step Guide on How to Fix Yellow Flame on Gas Stove

Step One: Determine if There Is a Flame

Sometimes, the gas stove’s yellow bottom-light will not be lit appropriately up; however, it may also be unlit ultimately (the power to your lamps/appliances are still on). So, instead, look directly at the red-hot coils beneath the burner. If you do see flames, they are most likely yellow.

Check for this symptom by turning your stove on, let it heat up for two to three minutes. Then, turn the knob to “pilot” or “light.” If that does not work, turn the knobs off and back on again while holding in both knobs.

Step Two: Clean Any Residue

If the yellow flame occurs because the stove was not properly cleaned, then you should clean it. You can use a commercial oven cleaner or use dish soap and water to wipe down the surface and let it dry before using your stove again. If you have a gas stove, then you are in luck. Unlike electric stoves, where the burner element is enclosed in the glass/ceramic top, gas burners are open to the air. 

Clean Any Residue

That means that when there is not enough oxygen for them to combust completely and produce what’s called an “oxygen-starved” burn, the flame will be yellow instead of blue. Then, all you have to do is supply more air by cleaning out or replacing your stove’s air filters, opening the window(s) in your kitchen slightly, or turning on a fan.

Step Three: Change the Stove’s Air Filters

If opening the windows and turning on a fan does not work, then try changing your stove’s air filter to see if that provides enough oxygen for it to combust correctly, which means you will get a blue instead of yellow flame. After you do this, please refer back to Step Two.

You may need to do this more than once. If the switch to new air filters does not work, you should consider buying a new stove or have someone look at your current one.

Step Four: Purchase a New Stove

If none of the above steps has helped you resolve this problem, it may be time to purchase a new one. There could be various reasons why your gas stove produces a yellow flame where there should instead be a blue one. However, it would require an expert in the field to come and investigate your stove, which would be extremely costly.

Even if you’re not willing to pay for this service, consider calling a professional who will come and give you some advice as it may help. For those interested in purchasing a new stove but don’t want to spend the money now, I would recommend saving up the extra cash needed to make an informed purchase.

Step Four: Try Switching the Knob

If you turn the stove on, let it heat up for two to three minutes. Next, turn the knob to “pilot” or “light.” This may not work every time, but you should try this at least once. If that does not work, turn the knobs off and back on again while holding in both knobs. If this does not work, there is a possibility that your knob may be broken. In this case, you will have to replace the knob.

Step Three: Check for Gas Leaks

Take a look at the connections on your stove. Look for any signs of corrosion or rusting around the connections and hoses. Corrosion can be a sign of gas leaks. If you have any corrosion or rusting, it is time to replace the connections and hoses.

Check for Gas Leaks

There is a possibility that the corrosion or rusting could have been caused by a gas leak, which can be very hazardous. This will help in how to fix yellow flame on gas stove.

How Do You Adjust the Air Intake Valve on a Gas Stove?

One of the most common problems with gas ranges is a yellow flame. This typically occurs when the air intake valve doesn’t open all the way or stays open too long. As a result, the air flow mixes with the gas, creating solids that turn your stove’s flames yellow. If you have this problem, try adjusting the air intake valve for smooth blue flames. You can do this yourself by following these steps:

  1. Turn off the stove’s gas supply valve at the source and disconnect the flexible gas line from underneath your stove if you haven’t already done so.
  2. Find the air intake valve on the front of your range. It is a knob with a small, oblong handle.
  3. Turn the knob counterclockwise to adjust the valve, so it isn’t fully open or is only open for a short time. You should be able to hear gas released through the valve when you turn it. This means you have successfully adjusted your stove’s air intake valve so it won’t release excess gas into the air.
  4. Re-connect your stove’s gas supply line and turn on the gas supply valve at the source.


There are many possible causes for yellow flames on a gas stove. If you have an electric or natural gas stove, the flame is probably normal and not a concern. Below are some standard solutions to fix this issue with your gas stove type if it is indeed burning yellow instead of blue.

These fixes will work on both propane stoves as well as those that use something other than propane, such as natural gas or liquid fuel like kerosene. The reason for yellow flames can be caused by everything from dirty burners to clogged lines in the ventilation system or even just cooking oil residue buildup!
