The gas burner does not burn well: an overview of typical faults and how to fix them

Has your gas stove never let you down, but suddenly there are problems with burning the burners? The situation is, to put it mildly, unpleasant, do you agree? Do you want to try to restore the equipment to work on your own, but do not know where to start diagnostics?

We will help you figure out why the gas burner does not burn well, we will show you how to find the breakdown and fix it on our own. We will also talk about the most common malfunctions leading to a problem with the combustion of a gas burner. Moreover, many of the reasons leading to abnormal operation of gas stoves can be eliminated quickly and without significant costs. Here are illustrative photos and thematic videos.

Why are the burners not working properly?

The most common reason for problems with the performance of the gas stove is dirt clogged in the nozzle of the nozzle. These structural elements are located directly under the burners. Therefore, particles of food and detergents often get into the channel intended for dosing gas.

They burn out under the influence of high temperatures, but residues still accumulate and over time interfere with the supply of gas to the burners. Which leads to a partial and sometimes complete loss of their performance and poor combustion.

The described procedure is uneven, so combustion problems arise for each burner separately.

The situation with the contamination of the nozzle is one of those that can be solved by yourself. Since this does not require special knowledge and skills, as well as a rare tool. Before starting repair work, we recommend that you first familiarize yourself with gas stove device.

In addition, there are a number of steps you need to take to troubleshoot the problem:

1. Remove the lid from the hotplate.
2. Dismantle the hotplate. This is easy to do - it is simply removed from the seat with one movement of the hand.
3. Dismantle the gas stove table to gain access to the nozzle. For which it is sometimes necessary to unscrew a few screws.
4. Clean the nozzle bore.

The last procedure is performed using a pre-prepared needle or a piece of thin wire. Which, for convenience, must be bent at an angle of 90 °, and this will also prevent the homemade device from dropping into the nozzle channel.

For cleaning, a needle or wire is inserted into the nozzle channel and reciprocated.

It will be possible to remove the loose dirt by opening the gas valve for a few seconds. In this case, it is not necessary to ignite the "blue" fuel.

It is possible to check the quality of the work performed without installing the gas stove table.

What is the burner for:

• installed in the workplace;
• cover with a lid.

And then the usual procedure for igniting the flame is performed. If its parameters are not inferior to those of other hotplates, then the troubleshooting procedure is considered successful. After that, all that remains is to mount the table and install the burners.

Rarely, but it happens that it is impossible to clean the nozzle from contamination in the installed position. As a result, it will have to be dismantled. But there is no need to be afraid of this, since the whole procedure, if you have the right key, will take several minutes. It will then be easier to clean.

It is also recommended to wash the jet with any conventional detergent after it is completed. Next, the device must be wiped dry and you can start assembling.

Other causes of unstable combustion

Unstable burning of the burners can be caused by a number of reasons. Sometimes it happens that the openings of the burners, which cut through the flame, are clogged with combustion products. Which is the reason for the loss of partial loss of burner performance.

The problem is solved by cleaning the holes. Which in some cases can be done with the help of improvised means and without even dismantling the contaminated burner.

But it is still better to get it out and wash it well with detergents, since such a procedure helps prevent the problem from recurring for a longer period.

If there is an excessive amount of grease in the tap, then the gas in the required volume does not enter the burner. This leads to the blockage of the channel through which the "blue" fuel is supplied to the burner. But this happens when some work was performed with the crane or a new product was installed.

Problem # 1 - gas stove smokes

The specified reason is a sign that the energy carrier is not fully combusted. This can lead to a fire hazard. Therefore, the problem should be resolved promptly. And it is not difficult to do this even yourself, since in most cases the cause can be identified on your own.

And the main ones are:

• clogging of the diffuser (diffuser) of the flame;
• contamination of the nozzle.

That is, the same reasons lead to the formation of soot as with simply poor gas combustion. Therefore, they are eliminated in the same ways as indicated in the previous section of the article.

In addition, the deformation of the flame diffuser leads to incomplete combustion of the gas. This happens with the active use of a gas stove or low quality of the product itself, which cannot be restored. That is, the only way out of the situation is to replace this element.

Sometimes it happens that soot appears due to the low quality of the gas. For the most part, this concerns fuel that is supplied to consumers in cylinders. And in this case, it is simply necessary to replace the container with another one.

If gas cylinders are used, incorrect adjustment may be an additional cause of soot. reducer fuel supply. The remedy is to make the appropriate settings. For which it is better to call a specialist.

Problem # 2 - flames change color

This reason for the incorrect operation of the burner indicates that the resulting gas-air mixture contains an insufficient amount of oxygen. for complete gas combustion.

Moreover flame discoloration - the malfunction is more dangerous than it seems. The reason is that when gas burns with any flame other than blue (for example, red, white, orange), it leads to mass formation carbon monoxide. And he is deadly. So, even with an insignificant concentration of 0.1%, acute poisoning and even an accident can occur.

Therefore, having identified that the gas burner does not burn well, you need to immediately clean it of dirt, as this ensures fire safety use of equipment.

The whole procedure consists of 2 stages:

1. Burner cleaning, her cover;
2. Cleaning the jet nozzle burners.

Detailed information on how to perform the listed operations efficiently is presented in the previous sections of the article.

In the case of the wrong color of the flame, even the owners of newly purchased gas stoves should not ignore the cleaning. Since on their structural elements, including jets, burners, taps, there is a protective lubricant to which dust and dirt particles stick, which can negatively affect the amount of air supplied.

If cleaning has not led to the normalization of the operation of the stove, then the reason for the poor-quality process of the formation of a gas-air mixture should be sought in gate settings. That is, a device that regulates the amount of air supplied to the gas. It is better to entrust the setting of the gate to a specialist who at the same time will check its performance.

If the owner of the stove decides to carry out the adjustment on his own, then you should know that moving the flap towards the nozzle leads to overlap of the primary air intake channel. Which will lead to even greater problems with gas combustion. That is, the correct solution would be to move the flapper away from the nozzle. And how much is revealed experimentally.

The signs of normalization of combustion are:

• the blue color of the flame;
• the length of the flames is within 2-2.5 cm;
• absence of noise, separation of flame tongues.

Rarely, but it happens that the cause of an incorrect combustion process is low quality gas in the pipeline. It will be possible to identify this reason by a comparison method: if the neighbors have the same problem, then we can conclude that the energy carrier is of poor quality. In this case, you need to contact the gas service. Although it is unlikely that such a situation can be changed quickly.

If the cylinder gas changes color, then you can try connect to gas stove new bottle.

Problem # 3 - noise and flame separation

Noise and flame-off indicate that the gas pressure is too high.

In this case, it is unlikely that it will be possible to fix the gas burner yourself, since the cause is one of the following malfunctions:

• Wrong nozzle size. The problem is eliminated by selecting a product whose throughput corresponds to the characteristics of the slab. The procedure for dismantling / mounting the nozzle itself is simple, but the selection of a new product will cause difficulties.
• Incorrect position of the gate (damper). The malfunction is eliminated by adjustment, that is, by changing its position (the procedure is described in detail in the previous section of the article).
• Incorrect flame diffuser holes. The problem is eliminated by selecting a new product. Such a malfunction is inherent exclusively in gas stoves of a new generation.

If the issue with the noise and separation of flame tongues arose when using bottled gas, then you should pay attention to the reducer. Since the cause, most likely, will be its breakdown. Which is easiest to eliminate by purchasing a new similar device.

We have another article on our website, where possible causes of burner noise gas stove and ways to eliminate them.

Problem # 4 - gas smell when the stove is on

Such a malfunction is one of the most dangerous. Therefore, measures to eliminate it must be taken immediately after detection.

The reasons for the appearance of gas when the stove is turned on can be:

• leakage at the junction nozzles with a gas supply tube or at the junctions of the two indicated structural elements of the cooking appliance;
• wrong setting - in this case, it will be possible to fix the problem by changing the position of the gate according to the instructions described above.

Sometimes it will be necessary to replace the nozzle with a product with a suitable channel diameter.

It is possible to identify a gas leak yourself, since for this you need to perform only a few simple steps:

• remove the burners;
• dismantle the slab table;
• replace the burners and their covers;
• apply the previously prepared soap solution to the nozzle-to-tube junction or at the joints of the indicated structural elements of all burners;
• turn on each burner in turn to check the tightness.

If after performing the last procedure there are identified bubbles, then this means that the assumption about the leak was confirmed.

And then you just need to call gas company specialist to troubleshoot the problem. Which is performed by replacing worn-out parts. You should not use it until the gas stove is fully operational. As it can end in fire or explosion.

Rarely enough, but it so happens that the cause of the depressurization of the gas pipes of the stove is the O-rings and washers. Their defects, destruction lead to malfunctions.

Remedy: replacement with new ones, but this work should be entrusted to a specialist. This must be done, if only because he knows how to replace the damaged part.

Problem # 5 - burner damping

In addition to those described above, there are often a number of malfunctions of gas stoves, leading to the damping of the burners.

These include unstable combustion with the following symptoms:

• poor operation of the burner, which ends with the extinction of the flame;
• the burner does not work well, while the handle of its tap is difficult or impossible to turn;
• All stove burners are not burning well.

Since the listed breakdowns are considered typical, you need to get to know their features better.

When the burner goes out, the combustion can stop both immediately after ignition, and later, but in any case, the reasons will be the same.

The main reasons for stopping combustion include:

• Clogged injector nozzle. It is possible to eliminate the malfunction by cleaning (how to do it correctly, described above) or by replacing the product.
• Temperature sensor does not heat up when burning. As a result, a command signal is generated that ignition has not occurred and the gas control system shuts off the supply of energy. The reason is usually careless handling of the temperature sensor, as a result of which it takes the wrong position.
• Malfunction of the gas control system, which leads to its incorrect operation. In this case, you will have to replace the electronic valve or thermal sensor. Sometimes it is necessary to change the entire system as a set.

In some cases, the burners may not only work poorly, but simply not turn on.

Breakdown of the electric ignition system

It is easy to identify faults related to this category, since it is enough to ignite with matches. And, if the gas ignites, but not in automatic mode, then this will be proof of a malfunction of the electric ignition.

And the reasons are traditionally:

• ignition button breakage - this happens due to defects, resource depletion;
• malfunction of the autoignition unit, which is responsible for generating a spark when receiving a command signal from a button.

If the gas burner with electric ignition does not ignite due to the listed malfunctions, then you should be ready to replace the failed elements of the stove structure. And this must be entrusted to specialists.

When one burner is problematic, then first of all you should pay attention to the spark when the button is pressed. If it is there, but is directed to the side, and is weaker than on other burners, then the cause of the breakdown is in the candle. Moreover, you should not rush to replace it.

Since it is often the fault of incorrect operation is a layer of dirt that has covered the specified device, because of which the spark does not correspond to the established parameters.

In this case, all that is needed is to clean the surface of the candle from food debris, detergents, carbon deposits. They act in the same way if a wire sticks to its body and breaks it through the insulation onto the plate body.

In addition to cleaning it from dirt, it is necessary to remove traces of oxidation from the steel rod.

If it was not possible to restore operability by cleaning, then this indicates the destruction of the insulation of the candle or its wiring. In these cases, both elements are replaced. What must be entrusted to the master.

When there is no spark on all burners, this indicates a break in the wiring from the button to the electric ignition unit. This can happen due to a defect or mechanical damage to the wire. Usually, such a malfunction is typical for private houses.

In addition to problems with the burning of the burner, gas appliances also experience other breakdowns. We recommend that you familiarize yourself with popular plate breakages and methods of their repair.
