Have you ever seen the flame on a gas stove turn yellow? If you answered yes, you should be concerned. Yellow gas flames are bad for your stove, utensils, and health. It doesn’t matter if you have propane or use a natural gas stove; flame issues can hit any gas burner.
The flame is critical to deliver precise heat control and provide efficient heat transfer to heat cookware while cooking. So, when the stove’s flame turns orange, there’s an issue with the flame on your gas stove that needs fixing. Flames that are orange or yellow can make your gas stove dangerous. Incomplete combustion causes orange, yellow, or sooty flames, which can lead to carbon monoxide buildup in your home.
There could be an issue with the air-gas combination or the appliance’s gas pressure. You can learn the major causes of yellow flames on stoves and burners in our guide. By the end, as an experienced do it yourselfer, you’ll see how to fix the issues with your burner gas valve. You’ll also prevent any chance of carbon monoxide poisoning by having complete combustion as you are supposed to when your open stovetop is working correctly. (Learn How Deep Is Gas Line Buried)
What Causes A Yellow Burner Flame?
Why do I have a yellow flame on stove instead of a normal gas stove flame?
The most straightforward reason is that your stove has issues with proper combustion!
Your gas stove’s burners need to be cleaned, or the problem involves adjusting. Otherwise, the stove could leak a dangerous amount of carbon monoxide gas if it isn’t working correctly.
But what causes your stove flame to turn orange in the first place?
When there is a supply of oxygen in the stove, the flame, which should be blue at first, does not ignite.
However, the oxygen is continually squandered, resulting in a blue gas flame with an orange or yellow tip.
As a result, the most common cause of your gas stove suddenly bursting into orange flames is an inappropriate mixing of oxygen and fuel.
The problem may be concealed in the orifices. Examine them for any obstructions caused by soot buildup, as an inconsistent fuel supply could cause this to the burners. Orange flames erupt while the soot is burning.
If the problem isn’t with the orifices, the orange flame tips are that the air-to-fuel ratio isn’t being met appropriately.
It’s possible that the air shutter was damaged. Because of the faulty gas supply, orange flames will appear.
The following are the most common causes of yellow flames on a gas stove.
Dirty and clogged burners are the number one thing that causes yellow flames.
Here are some steps to fix yellow flame on gas furnace or stove.
You’ll need a few basic supplies:
- Dish soap.
- Vinegar or lemon juice (depending on your gas stove).
- Non-stick baking sheet with edges.
- Paper towels.
Before you start cleaning, make sure you’re wearing your gloves. If your baking sheet isn’t non-stick, line it with baking paper/ parchment, so nothing sticks.
- Apply a light coating of dish soap, vinegar, or lemon juice to your cooktop and place it on the prepared surface (type of gas stove may change the method).
- Rinse with hot water and dry the area after rubbing it clean.
- Clean away material from burner holes: A yellow flame on your gas stove might be caused by a buildup of dirt and debris.
- Use a toothbrush to clean out the burner holes or use compressed air to blow away any pollutants that may cause the problem.
How Do You Fix A Orange Flame On A Gas Stove?
If you notice a problem with the color of the flame changing, you should address it as soon as possible. Here are some reasons why your gas stove may have an orange flame and how to remedy it. (Learn How To Arrange Lava Rocks On A Gas Fire Pit)
Ensure you’re using the proper orifices for your range (whether you’re using natural gas or liquid propane LP).
Make sure the gas pressure regulator valve is changed, and the brass orifice is adjusted along with this change.
Make sure the stove’s gas-burning orifices are clean and free of debris. In addition, you must thoroughly clean the stove to ensure that the igniter and openings are free of clogging.
Make sure the portholes and burners are clean and clear of debris. Cooking grease on any spillovers may obstruct these holes, affecting the flame’s color.
Note: After cleaning them, make sure they are in the same position as before, as this can change the color of the flame.
Humidifiers appear to alter the flame color from blue to orange. If you have a humidifier near any stove, turn it off and observe what happens.
Another problem that might cause yellow and orange flames on gas stoves is the fuel-to-air ratio.
There will be no complete gas-burning if your gas range burner doesn’t receive enough air.
If this is the case, adjust the burner’s air shutter to allow more air, gas burners should then burn blue.
Open Your Stovetop:
- Remove the stove’s top grate and lift the stovetop to reveal the burner’s pipework.
- Behind the burner gas valves on most stoves are air shutters. (The air vent of the burner is covered by a burner gas valve, which is a tube or plate.)
- Remove the shutter’s screws and loosen them.
- Turn the burner on full orange flame and slowly open the shutter until the gas flame turns blue.
- Replace the top grates, tighten the screw, turn off the burner, and lower the stovetop.
You should have set the correct air supply for your gas valve.
How Do You Fix A Yellow Flame On An Outdoor Gas Burner?
Everything is considered, and your stove’s flame color shows temperature. However, since blue flames are the hottest, we can now include yellow, orange, and red flames for cooler.
However, seeing a yellow flame on a gas stove might be frightening. There are several reasons why a gas stove’s flame appears yellow.
The first reason is a lack of gas flow when the regulator is set too low. To fix a yellow flame on your burner, you only have to identify the source of the orange flame problem.
Turn off the gas and let your burner cool to fix a yellow flame. Liftoff the top grates and pull out the stovetop to expose your burner piping.
The air shutter is usually behind the burner gas valve.
You’ll see a sliding plate and tube covering the burner air vent. Loosen the set screw holding the shutter and turn the burner on.
Slowly open the shutter until you get a blue flame on your outdoor gas stove.
What Causes Yellow Flame In A Propane Burner?
The color of the flame is a primary concern. If your stove flame is yellow, red, or orange, something is amiss, and you have unburned gas.
With a yellow flame, you risk releasing a lot of carbon monoxide while cooking, even if you can’t smell gas. (Read Pellet Stove Vs Propane)
Carbon monoxide is highly harmful, and the symptoms of carbon monoxide poisoning vary.
Your stove’s normal flame should be blue, but it can also turn yellow, orange, or red.
A blue flame shows incomplete combustion, suggesting your stove is in great shape and won’t waste fuel.
Yellow flames suggest your stove is defective, meaning it is not fully combustible, wastes fuel, and is unhealthy. However, there may be air gas or gas pressure issues.
One of the most typical problems with a Gas Stove is the Yellow Flames. This problem is caused by a gas leak or a bad gas valve. There are several ways to fix the yellow flame issue.
The simplest is to replace the gas valve. However, the Gas Valve still has some gas, so test it before removing the old one.
Test with a match or lighter. If you can light the Gas Valve tip, you’re ready. Gas valves are usually the size of a quarter.
In most cases, food waste buildup causes blockages; however, lack of fuel, a dirty burner, and other factors can also create obstructions.
If your camp stove only has a yellow flame, try these fixes. You can discover a solution:
Unattended oil or food spills on the stove burner can generate residue buildup on the stove flame. But the flame will still be hot as usual.
If you spill fatty meals on your stove, you may have residues. These compounds will burn off when you fire your camp stove and may reduce the amount of fuel burned.
However, your stove may smoke if you have food particles in the bottom oven or top burner. This will ensure that an oil or food spill causes the yellow flame.
Your camp stove burner may be clogged by debris other than oil leaks.
Beyond oil spills, you may have food particles caught on the burner. This could be from earlier camping or cooking. If you don’t clean your camping stove properly, the food residue will cause a yellow flame.
Running out of fuel can cause a yellow flame on your camp stove, in addition to oil spills or a filthy burner.
But for a good flame, you need a lot of gas. So, as the fuel runs out, the flame often suffocates. The stove’s flame won’t get hot enough to cook.
If you smell gas, get in some fresh air until the problem is fixed and you have complete combustion of the gas again.
