A gas cooktop’s flames should be blue, powerful, and absolutely even. As stated, many times before, a healthy flame on a gas stove can save you from thousands of complications which you may not have known.

If your gas stove is not working properly then it means you are getting contracted with these problems. You can easily know whether cooking on a cooktop is healthy or not by the flame of its color. A gas flame must have to be blue.

Apart from that, uneven or lopsided flames are also a problem in terms of cooking and can cause variety of issues.

The good news is that this does not necessarily indicate that your stove requires repair, but rather that it may only require a correction to return to working condition.

Whatever type of flame problem you have, we have a solution. However, in order to effectively identify your particular problem and get it treated quickly, you must be able to list the symptoms.

Flame – Too High on Burners

In case of new Gas Stove

Starting from here, I personally believe, a high flame on gas stove is more dangerous than any other thing. It usually occurs when you get your cooktop installed and connected it with liquid propane, which is a natural gas using stove.

LP has a greater pressure and requires that your gas stove be adapted to utilize it. If not converted, the enormous pressure will produce massive flames.

To fix this, get the manual on hand and check whether the installation has been done by the book or not. You can also contact the support team of your gas stove’s company or can contact us.

In case of Old Gas Stove

If you do not have a new stove, it is considerably more probable that the problem is with the knob adjustment.

For example, you are trying to simmer on your gas stove, however, your gas stove either boils or burn it, making you lose the control on your gas cooktop. Hence, all the credit in this flaw goes to the knobs.

To rectify this, disconnect the gas supply of your gas stove for your own safety. This is because you are about to replace the knobs and there might a risk of seeping gas into your home since you are about to open your gas stove’s burner connections.

After that, you may remove the control knobs from the stove.

You should check for the manual of your gas stove’s company and model to do this task efficiently.

Some types allow you to spin the actual knob connections, while others need you to turn screws. Typically, clockwise rotations alter how much gas the flame receives on each level, allowing you to manually reduce the strength of the flame.

Flame – Too Weak on Burners

Interacting with the weak flames on your gas stove’s burner? To rectify this, simply do the reverse engineering. Means, you should do the opposite of above mentioned procedure.

But you should also know that this is not always the case. Most of the times, week flames on a gas stove are not caused by the control knobs.

Sometimes, the burners on your gas stove are not getting sufficient gas for creating accurate flames.

Furthermore, if you checked your gas stove and there is nothing wrong with the positions of your stove’s burner head and cap then there is only one thing to check know i.e. the regulator.

That is because the gas regulator is the component in your stove which controls gas pressure. Replace it and everything is good to go.

You can find it beneath your cooktop near the gas line with the help of torch or flashlight.

However, it is highly advisable to call a professional in this regard, as you can cause more harm than good. Since it directly affects the gas line to the burner and must be securely sealed to prevent gas leaks.

Flame – Missing in Some Spots

Missing spots of flames on your gas stove can be observed as some sort of gaps inside of your stove’s flames. That is due to the clogged burner holes.

Whenever you light gas on your stovetop, flames on it gets dispersed by burner cap and comes out from all of the tiny holes in the burner head. Food particles can become trapped in these tiny holes over time.

Moreover, if you recently cleaned the burners of your stove, it may also cause the dirt to be clogged inside them. Therefore, when trash is moved around with a sponge, it is readily pushed into burner holes.

To fix this, allow the burner to cool down before cleaning the burner head slots. Use a toothbrush, a piece of wire, pin or even a needle to clean these holes.

Just insert it inside and floss the trash out.

However, you should select a strong object. Using a toothpick is not advised since the tips might break off and become caught in these tiny holes.

blue flames

Flame – Higher on One Side

Lopsided flames where one side is higher on other side is majorly due to indication of an improperly positioned burner caps and heads.

A misaligned burner cap might result from bumping the burner or removing the cap to clean your stove.

That occurs when the cap sits higher on one side and lower on the other. Hence allowing more gas to escape from one side and less from the other. Resulting in uneven flames.

Fixing this is as easy as a piece of cake.

  1. Switch off the burner
  2. Let it to cool Take up the burner cap
  3. Readjust it

It should have to be exactly on level and sit firmly on the burner. If it wobbles or seems uneven, keep repositioning it until you get the right fit.

Pertinently, you should check behind the burner cap for any blockages, and if found, clean it properly so it can sit down easily.

The Yellow / Red / Orange Flame:

The final problem that might arise with your gas stove’s flame is that it becomes yellow instead of blue. Typically, this is a condition that may be remedied by cleaning.

As stated time and again, blue flame is the perfect indication of healthy gas stove. While when there is some food, spillage or debris stuck in your gas stove then its color may change to yellow, orange or red.

A blue flame on your stove indicates that it is just generating gas. When food or other material burns in a gas flame, the color changes to yellow, orange, or red.
