Many people prefer the power of a gas cooktop to give even heating to many of their favorite meals when it comes to cooking. However, one of the most aggravating issues that a gas stove might have is an uneven or very faint flame. Even on the maximum level, the flame is no stronger than it would be on the lowest setting.

Here we have tried to give the best possible and easiest solution to this query via which you can repair the flames of your gas stove by yourself without paying a single dime to any professional / expert.

Most of the time, a faint flame on your gas stove is not an indication that you need a repair. So, before you start digging through your toolbox to disassemble your stove, you might want to look at the actual burners on your stove.

How do you adjust the flame on a gas stove?

Following these 3 steps which are mentioned below and you can easily attain your results within 5 to 10 minutes.

Step-1 Check Burners:

Checking the burner of your gas stove is the top most  thing in order to adjusting the low flame on your gas top and majority of times it only requires one to check burners of the stove only.

Burners play a huge role in the functioning of a gas stove and the majority of the time, by checking your burners you can get a solution to your problems.

Take off the cap of your burner which covers your burner holes, and clean them properly if you find them dirty or clogged. Now, find the Brass Jet / Nozzle fitting underneath that feeds the gas system (it is a small hole that can be seen from upward inside your gas stove system).


If your brass jet / nozzle is clogged then it would be appropriate to clean it with a needle. Never use a toothpick, because toothpicks can break down and make the matter more adverse.

Furthermore, also check for the igniter and the orifices whether they are clean or require your immediate attention. 

Step-2 Air Shutter:

An air shutter is a metal collar that controls how much oxygen is blended with the gas that flows to your burner. It is a very useful item because fireplaces rely on air to function.


This screw is close to the burner at the end of the stove’s barrel or sometimes behind the gas burner valve. Turning this screw clockwise will decrease the flame size.

You can clean the air shutter with the burner lit on low, turn the adjustment on the screw while watching the flame reduce in size. Adjust the flame height to the top level as the top burner.

Step-3: Adjustment

After doing the adjustments, turn the burner up to its maximum capacity and then quickly turn the knob to low if the flame blows itself out then the flame is set too low and needs to be increased. Turning the screw counter-clockwise will increase. Adjust the flame to a suitable level but it should be high enough for the flames to remain lit.

Repeat the test and keep on adjusting as per your requirements.

Lop-sided Burner Cap:

If the burner cap is not properly positioned, it might result in a low flame because there is not enough gas getting to your Burner Head, thus the gas is escaping out of it due to this leakage.  

You can also observe that your gas stove’s flame is lop-sided and uneven and, in many cases, this happens dint to the positioning of the burner which also causes problems for lighting the burner and your gas stove take quite a long time also in this regard.

Filthy Burner Head:

One of the most common reasons for weak or uneven flames on your gas stove is a dirty/filthy burner head. It is something that can easily happen with the passage of time. 

The burner head is encircled by tiny openings that allow gas to escape and be ignited, resulting in flames. These slots, however, are prone to becoming clogged/blocked by oil, spills, splashes, or any other food particles from your daily cooking.

But the problem doesn’t stop only there, when cleaning your stove, these items can even be pushed within the slots by sponges.

If you are of the view that the flames will burn away these particles, then you are absolutely wrong because they do not get burnt away rather, they create a hindrance in operationalizing your gas stove making it much more adverse than it actually is.

Control Valve:

If the problem still occurs even after trying so hard, there could be the reason that your Control Valve is responsible for causing a problem and there may indeed be a need for a part replacement in your future.

The control valve on your gas stove is in charge of regulating the gas pressure. This is what permits you to alter the intensity of the flame throughout your stove’s many settings. If the flames on your stove are flickering or you are unable to regulate the strength of the flames, the control valve may be malfunctioning and must be changed.

How do I increase the flame of my stove?

The adjustment of your gas flame as mentioned in the above points can also be lucrative in increasing your gas stove’s flames. If you clean your stove thoroughly, including burners, igniters, orifices, brass jets, or nozzles then, the chances are your stove’s gas flame will be increased at the very next second and you won’t be needing to do anything.
However, if the matter still pertains then you can make amendments to your air shutter screw, and can rotate it in a clockwise position to increase flames.

Final Thoughts:

This not only ends here if all of this does not work for you (of which probability are very low) then try to contact your Stove’s company and tell them about your grievance before asking any professional or expert.
