Why the burner on the gas stove does not work: common causes and solutions

Additional Information

It is not forbidden to use classic household methods, such as: soda, vinegar, citric acid or alcohol.

To clean the gas oven, you can use shop and folk remedies cleaning.

Use a regular foam sponge, you can use a soft washcloth or cloth. Apply funds only in a creamy consistency, evenly distributing them over the enamel.For a complete cleaning of adhering grease and stains, leave for 1-2 hours so that the product removes all dirt and germs from the surface of the gas stove. Next, remove the burners and soak them together with the cleaning agent in water for 1-2 hours.

Then rinse everything with a damp sponge, wipe with a cloth and put the dry burners in place.

Please note: Follow the safety precautions when using the stove and do not panic if you smell gas. Just turn off the gas pipe valve and try not to be in the apartment until the specialists arrive

Tips:

Do not unscrew the gas knobs to full power, as if the gas supply is too powerful, the flame from the burner can come off, thereby releasing carbon monoxide into the air.
Do not leave the switched on gas stove unattended.
Monitor the quality of the equipment, if you see a yellow flame, the oven in the gas stove does not burn, or some other problems occur, call the experts in a timely manner.
Do not splash liquid onto the surface of the stove, as this may cause the fire to go out and cause gas to leak.
Check your gas water heater.
Pay attention to whether the hood is working. It is very simple to determine this, you need to bring a burning match to the chimney, hold it for a while, if the flame is drawn in, then the hood is working properly

If the flame burns as usual or deviates to the side, then the water heater cannot be used.

It is necessary to periodically monitor the operation of the oven.

Safety rules for stove repair

When inspecting and repairing the stove, you must follow simple safety rules - turn off the fuel supply, turn off the power supply, children and animals should not remain in the room. Upon completion of work, you should make sure that the burners burn evenly and that the connection between the stove and the gas pipeline is tight.

In case of a serious breakdown, it is undesirable to carry out repairs on your own, without the appropriate experience. In this case, it is better to call the master from the organization with which the contract for the maintenance of gas equipment has been concluded.

For unauthorized intervention in the gas supply system, liability is provided for, specified in Article 9.23 of the Code of Administrative Offenses. The fine will be from 10 to 30 thousand rubles.

If a fire or explosion occurs through the fault of the owner of the equipment, he will be charged in accordance with clause 6 of part 3 of article 158 of the Criminal Code of the Russian Federation. The amount of penalties for illegal actions: from 100 to 500 thousand rubles. There is also a punishment for this offense in the form of imprisonment for up to six years or forced labor for up to 5 years.

If you have a faulty electric ignition

They are now equipped with almost all devices, which has a positive effect on ease of use. Let's decide for a start how electric ignition is arranged and works.

Electric ignition consists of four parts:

• transformer (block) operating from the mains for 220 V;
• electrical wire leading from the transformer to the ignition mechanism;
• ceramic candle;
• the ignition button located on the control panel next to the rotary switches.

The mechanism of operation of electric ignition is as follows:

1. When the button is pressed, the circuit closes;
2. The transformer generates current for the spark;
3. The impulse is fed through the wires to the gas burner;
4. The ceramic candle produces a spark and the burner ignites.

It is noteworthy that the candle fires on all burners without exception, however, only the one to which the gas goes is ignited.

It is very important to ensure that there is always one voltage in the network - 220 V. To protect your stove, you can buy a household voltage regulator, which will save you from unexpected power surges

Otherwise, short circuits and unstable operation of the network negatively affect the electric ignition, and can cause a breakdown. If your hob is experiencing the following problems, then the problem is with the ignition:

1. turn on the button, but the ignition does not work;
2. sparks one or all spark plugs;
3. you release the button, and the ignition works.

The button is turned on, but the ignition does not work

The first and most common cause is contamination of the mechanism button and / or burner with dirt and combustion waste. Cooking entails splattering food all over the stove, so this problem is not uncommon. Clean the ignition button, wipe the burner clean, clean the nozzle with a needle or any other thin stick, wait until everything is dry.

One or all spark plugs spark

If the spark plugs on all burners sparkle orange or yellow, work intermittently, then the problem may be in a faulty electric ignition unit. It needs to be replaced, but it is extremely difficult to do it yourself. The block is located in the middle of the panel, it needs to be disassembled, the contacts disconnected, so it is better to trust professionals in this situation. To finally make sure that the fault is in the transformer, do the following:

• in the dark, with the lights off, turn on the ignition button;
• if there is a spark on all burners of the color described above (yellow, orange) - the unit definitely needs to be replaced;
• if the spark is blue, the block is good.

If the integrity of the spark plug is broken or its stem is oxidized, it will sparkle orange or yellow, intermittently. This is solved by replacing the faulty spark plug. However, such problems are quite rare and this is due to the design of the candle itself. It is a steel wire, one millimeter thick, enclosed in porcelain. For a candle to become unusable, it must be in very unfavorable conditions of high humidity or be subjected to a blow.

You release the button and the ignition fires

This may be due to a faulty transformer or contact oxidation.

When washing the panel, boiling water, the liquid can penetrate into the middle of the device, onto the contacts. With constant leaks and heat coming from the included burners, the contacts are oxidized. They get rough, can stick together, break. Their technical cleaning and high-quality drying will help.

If there is a lot of fat: how to wash a gas stove

For the highest quality cleaning and cleaning of all contaminants, it is necessary to carry out preliminary preparation.

We sprinkle soda on a damp surface in an even layer and let it stand for 30-40 minutes. This method is not difficult and makes it possible to clean the stove and oven. The oven can also be cleaned in this way.

If there is too much fat, then it is better to apply a cleaning agent on it and leave it for a while, and therefore wipe it off

After waiting for time, you can start cleaning, water with baking soda must be removed from the surface of the stove with a soft sponge.

In no case should metal washcloths be used when cleaning the stove and oven, as they can harm the surface, but it is better to use a sponge and a toothbrush or cotton swabs, but this is in the most inaccessible places.

For cleaning grates on gas stove it is necessary to use the above written soap solution. Citric acid or juice, vinegar will also be excellent aids. They can be applied in place or separately. Ammonia and vinegar can remove dried and burnt dirt on the surface of a gas stove.

All gas stoves are equipped with removable handles.

The main thing here is not to rush, but to act carefully, slowly and without breaking the plastic.

Furnaces from different manufacturers certainly differ from each other. However, as experience shows, most design solutions from different manufacturers are VERY, VERY similar.

Shut off the gas supply with the shut-off valve before starting work.

Gas stove Hephaestus, Indesit, Electrolux, Darina (handles that need to be pressed and turned when ignited).

Just pull it towards you, along with the ring on which the symbols are drawn.

If you're having trouble, try treating with WD-40. Then, putting one knife into the gap between the ring and the handle itself, bend it a little. And from the opposite side, with the second knife, acting as a lever.

If it doesn’t go through the rag with pliers neatly.

Then soak the handles in water with the addition of fairies. After a while, the fat will turn white and come off with a toothbrush.

How to lubricate the swivel tight mechanisms of the crane?

Factory lubrication of the crane is designed for approximately five years. In Soviet times, gas workers used graphite grease (called NK-50), LG-Gaz41, LS-1P.

Graphite (crushed coal), which forms the basis of the lubricant, is able to fill in microscopic irregularities in parts, while reducing friction.

It has great refractoriness and does not dry out for a long time.

You can use grease or technical vaseline.

Tips for repairing gas stoves with your own hands

The main symptoms of a malfunction

If the gas oven has stopped working, it is necessary to carry out a basic diagnosis of the gas control. First open the top cover and the burner or burner table. To do this, unscrew and remove the two side plugs on both sides.

The visible signs of a malfunction are as follows:

• there is gas flow, but with the standard procedure of pressing the button, the flame does not appear;
• heating of food occurs unevenly: it can burn at the edges and be cold in the center, or vice versa;
• the oven does not close or the door is poorly pressed against the base, cannot be fully fixed;
• immediately after ignition, the fire slowly goes out;
• it becomes impossible to regulate the heat in the oven;
• as long as the handle is held, the gas cannot go out by itself;
• the oven smokes, and the fire at the same time emits a yellow-red glow;
• the flame emanating from the burners has a different height;
• the opening of the spirit door occurs with tension, as if it is being held inside;
• The oven gets very hot during low operation.

Important
If one or more of these signs occur, it is necessary to inspect the equipment and identify the malfunction. Gas is a dangerous thing, so if you are not confident in your abilities, then it is better to call the master to the house.

How is a gas stove

The design of gas stoves varies depending on the type of equipment. But all such devices include:

• burners;
• hob;
• oven.

>Some types of gas stoves are supplemented by an electronic control unit for the burner and other components. In particular, equipment is often equipped with a sensor that, if the fire goes out, cuts off the supply of "blue" fuel.

Burners

Burners consist of the following components:

• nozzle supplying gas;
• swirler;
• throttle;
• guides;
• lid;
• divider.

The latter divides the total flow of flame into several uniform tongues that go out. Diffusion and kinetic burners are used in old stoves. The first are installed in ovens. Diffusion burners are distinguished by the fact that the gas is mixed with air (due to this process, the fuel ignites) in a natural way. In modern stoves, combined burners are used.

Gas flow control

A thermocouple is located in the center of the burner near the stoves, which regulates the gas supply. This element, when heated, generates a current supplied to the electromagnet. The latter holds the damper open, so that the gas flows to the burner continuously. If the fire on the burner goes out, the thermocouple begins to cool. Because of this, the magnet is discharged, as a result of which the damper automatically closes, interrupting the gas supply.

This equipment significantly increases the level of safety of the plates. However, because of the thermocouple, you have to hold the knob down for a few seconds.

What to do when a problem is found?

It happens that the problem of weak gas supply and flame attenuation is caused by accumulated fat on the electric ignition or regulator.By cleaning them of contamination, you can eliminate this problem. Also check the spark plug, if the holes are clogged, the crown of the flame will be small or smoke.

It might be worth checking to see if oxygen is getting into the oven. To do this, check the tightness of the oven door.

Many, noticing that something is wrong, ask themselves: what is the malfunction and how to fix the stove yourself? However, if you encounter any problem that requires the appropriate qualifications, it is better not to try to fix the stove yourself. Such interference without the appropriate skills and knowledge is fraught with big problems.

If you yourself do not have the necessary tools and knowledge to troubleshoot problems, then calling a specialist will be the best solution.

If your gas stove has not passed the warranty period, then call the service center of the company where you purchased the equipment. If the warranty period has expired, then call a qualified specialist from other companies in your city. The master will be able to professionally fix all the problems and tell you how to care for the stove.

What else can happen

In addition, I will explain that the absence of a flame or its unstable combustion can be caused by a valve failure. Some models use high voltage safety valves, some use low voltage.

It is important to know which valve is in the oven, as outwardly they may look the same. If you install a low voltage valve instead of a high one during repairs, you can burn it

You don’t need to climb here on your own - this is the work of the master.

If the oven does not want to ignite and all of the listed components are working, the reason may lie in the gas supply.The problem is easy to recognize - in addition to the absence of combustion, when the knob is turned, there is no short-term hiss of gas. If the device is powered by a central network, it is better to check the shut-off valve, it is often tritely blocked. When powered from a cylinder, it makes sense to look at the state of the gearbox - suddenly it is also blocked. You also need to check the pressure in the cylinder, the gas suddenly ran out. If everything is in order, and there is no fuel supply, you should immediately call the gas service. The absence of gas in the system is a dangerous call and can lead to air.

If the oven is working, the flame pressure is catastrophically small, there is an incorrect ratio of the air-gas mixture supplied to the burner. If you want to increase the intensity of combustion, adjust the air damper.

How electric ignition works

Electric ignition provides the ability to ignite the stove safely. It reduces the possibility of getting burned to a minimum, because with piezo ignition you do not need to use lighters or matches. There is also no contact with the flame. With electric ignition, gas ignition occurs from the operation of a piezoelectric element on a gas device. The piezoelectric element gives a spark, after which automatic electric ignition is performed without the use of other devices. Repair of gas stoves with electric ignition can be done both with the help of a master and with your own hands: it all depends on the type of breakdown and knowledge about the operation of the structure.

Causes of failure

Why doesn't the gas stove work? In total, there are two most common causes of poorly working electric ignition:

• electrodes do not produce a spark;
• electrodes spark non-stop.

One of the reasons for the poorly working electric ignition of a gas stove is grease on the buttons. Solving the problem is very simple: it is enough to clean and dry the components of the hob, all the buttons in order to repair the electric ignition of the gas stove caused by pollution.

Another possible cause of failure is a cracked or broken ceramic insulation on the spark plug. A dirty spark plug can fail if dirt builds up on it. Also, the candle may stop working properly due to impaired tightness or oxidation of the rod made of steel. In addition, the element may crack due to careless handling. In this case, the spark starts to beat to the side. The only way out of the situation is to replace the spark plug.

When the spark generation unit (ignition transformer) burns out, the button you press does not generate a spark. If the piezo ignition does not work on a gas stove, it is easier to buy than to repair. It is realistic to repair this element, but it is too expensive - it is cheaper to purchase a new one.

When washing the stove, very often water enters the contact point of the power buttons. High humidity creates all the conditions for these contacts to oxidize over time, become rigid and break. In some cases, the opposite happens - the contacts may stick together and not work correctly. It is easy to solve a similar problem with a non-working auto-ignition - enough cleaning and drying, after which the hob will be restored to working order.

The oven does not work - the main reasons

Before calling the master to repair the oven, you should check if there is a gas supply in the pipe. To do this, try to light the burner on the hob.If gas enters the burner, then the oven is really faulty.

The second point that you should pay attention to is the presence of electric current in the network. Without it, the electric ignition will not work.

If everything is normal, then the oven is really faulty. Do not attempt to repair it yourself. Without the necessary spare parts and experience, this will be very problematic and even dangerous.

The main malfunctions of gas ovens for Gefest, Hansa, Mora and others include:

• When the ignition button is pressed for a long time, a hiss of gas is heard, but the flame does not ignite.
• The flame caught fire, but after releasing the button, it immediately fades.
• The flame burns for 5-10 minutes and goes out on its own for no apparent reason.
• The flame is very weak. The food cannot be cooked.
• The flame is very strong and it is impossible to regulate it. The food is on fire.
• The gas supply valve cannot be turned on.

The design and main components of the electric stove

The electric stove looks very impressive - it is a complex household appliance, but its design is quite simple, and all the main working elements are in a special heat-resistant case, which is made of stainless steel.

The principle of operation is similar to all electrical household appliances: the current, passing through the heating elements (heater), heats them up to a predetermined temperature. The stove has several burners on the hob, and their number varies: at least two, and the standard is 4 pcs. For example, the budget electric stove Mechta 15M has only two burners and a small oven, while the product of Belarusian engineers Hephaestus has a standard set of burners and a large oven.

The structure of the burners is quite diverse.The classics are burners on an enameled hob with a heating element inside, modern ones are solid ceramic surfaces with various types of heaters built into them. Consider the main types of burners.

1. Old domestic options are equipped with cast iron products, they slowly heat up and also cool down, creating a steam effect in the kitchen, but they are resistant to moisture and high temperatures.
2. Tubular spirals - they are made of a hollow tube, when heated, such devices not only give off heat, but also promote the circulation of warm air inside their case, which greatly increases their efficiency. These products are very difficult to repair yourself.
3. Ceramic burners are very simple in design, they are easy to repair at home - a nichrome spiral is laid in special cells in a circle and fixed. Modern models are increasingly using glass-ceramic solid plates - they are more durable and easy to clean.
4. Halogen devices are special burners with a similar emitter that are installed in different places on the hob. A stove with such burners provides fast heating, in a second, and low power consumption, so they are the most economical, but only professional craftsmen can do repairs.

All models of modern stoves use a power wire of a special section to transmit current to the burners, in addition, they are connected to regulators and thermostats that protect them from overheating.

Expert advice

Specialists in the repair of gas ovens are advised to pay attention to such points:

• Some models of gas stoves have plastic faucet handles put on the stem by means of a metal plate that is inserted into the groove. The handles begin to loosen as they are used, the record flies out and is simply lost. The problem can be resolved. It is necessary to take a metal canning lid and cut a plate of a suitable size on it. By inserting the part into the groove on the handle, such a delicate problem can be avoided.

• The extinction of the fire is connected not only with a lack of gas or a small amount of incoming oxygen. The problem may be that the iron part that is next to the burner heats up and causes current to flow. It delays the solenoid valve in its working position and may prevent the flow of gas to the burner. The problem is solved with sandpaper: it cleans the details.

  Advice
  If the procedure does not help, the gas stove also does not work, you need to change the thermocouple.

• If a misalignment occurs in a gas burner, it is worth checking its correct installation. If the problem occurs after washing, then the installation was not performed correctly. You need to remove the part and reinstall it. If the second attempt fails, then it is better to call the wizard. In rare cases, the problem lies in defective products, their overhaul is required. Although this case must be confirmed by the master.
• To make the fire in the oven stronger, since it started to burn weakly or goes out at the wrong moment, switch to blue fuel with a lower pressure: in this case, it is necessary to replace the burner nozzle (with a wider jet nozzle) and adjust the oven thermostat.

It's not just gas stoves that break. Our site has useful materials about breakdowns and repairs of electric stoves and their ovens, induction cookers, hobs, ceramic and glass-ceramic.

Solenoid valve - the second element of gas control

Most gas stoves and hobs are equipped with safety sensors - gas control solenoid valve. They cut off the gas supply in case of danger during the operation of the gas stove. If the gas burner or oven, for any reason, goes out or is blown out by an accidental air flow, the solenoid valve will shut off the gas supply after 5 seconds. The solenoid valve starts working after 4 seconds with constant heating of the thermocouple, if this does not happen or the time to turn on the burner has increased to 10 seconds, we can say that the gas control system of the stove is not working properly and most likely you need to repair the hob.

Nagar on pipes

Everyone is used to thinking that natural gas burns cleanly. This is true, but not 100%. In any fuel there is a minimum amount of impurities that form ash during combustion. Over time, it accumulates and clogs the holes.

What to do if the gas burner does not light up

The presence of soot creates pressure, the correct functioning of the device is disrupted. The flame may not burn or go out too quickly. Remove and clean the burner. Depending on the model of the oven, disassembly of the body is required here. Most often, to access burners with a jet, you need to remove the door and the bottom panel of the device.

I note that in some models, to dismantle the door, it is not enough to unscrew the hinge screws. The loops may need to be unfolded and folded back.

By the way, immediately it is advisable to pay attention to the condition of the seals. If necessary, they are replaced with new ones.

When opening the case, be aware that some metal parts have very sharp edges.

You have to be careful not to cut yourself

As a rule, the branch pipe is put on the gas supply pipe and fixed with 1-2 bolts. The burner itself can be of different shapes, but in fact it remains a piece of iron with holes, there is nothing to break here. However, there are air holes near the burners. If they are clogged, they should also be cleaned. Despite the simplicity of the work, it is better to entrust it to the master. If you act without experience, you can hook the gas control, causing it to break.

If cleaning did not help, it may be a violation of the tightness of the structure. In this case, there may be a smell of gas, which requires immediate repair.

Electric ignition does not work on two burners

In some cases, a gas stove on two burners does not light up. Sometimes ignition with a match helps - everything works normally, without interruption. The cause of this malfunction is damage to the spark plug responsible for ignition. We repair the electric ignition as follows: we clean the candle and look at its condition, perhaps it is enough just to clean the candle power wire.

If there is a crack on the element, we buy a new part and put it in place of the old one. Electric ignition can also break down due to a malfunction of the ignition button. Moisture or small debris could get into it, or it could be damaged mechanically.To fix this, you need to clean the oxidized buttons or replace them if they are mechanically damaged.

How to eliminate?

Most often, in case of violations in the operation of gas ovens, the owners are in no hurry to contact specialists, hoping to carry out repairs on their own. What breakdowns can and safely be repaired with your own hands? More on this below in our article.

• Cleaning the regulator knob. Shut off the gas supply before starting repairs. Troubleshooting starts with cleaning the faucets. After removing soot, dirt and grease from them, the spring is cleaned. The cork is wiped carefully, so as not to damage it. Violation of the surface will cause gas leakage. Use only a soft sponge. Next, the cork is treated with graphite grease, without touching the holes. The greasy coating is removed from the rod with a knife. After assembling the handle in reverse order.
• How to fix oven doors. Over time, the fasteners of the oven door become loose, then it does not fit snugly or does not close. To fix the problem, unscrew the fastening screws connecting to the plate. Having loosened them well, move the door in different directions until you find the position in which it has sat firmly on the hinges. To control, place a sheet of paper between the seal and the edge of the oven. If it does not clamp well, do the procedure again. After installation on the hinges, the bolts are tightened into place.

If it is noticed that the loss of heat is associated with damage to the seal located around the perimeter of the door, it will not be difficult to replace it.

1. Remove the old seal. In some oven models, it can be attached with screws, to get to them, pull off the protruding edge of the rubber, in the rest it is glued.
2. Wash the channel and door with liquid detergent.Clean off the remnants of old sealant or glue. Degrease.
3. Install a new seal, starting to mount it from above, then down and to the sides. Finish the process by joining the edges at the bottom center. If the elastic needs to be glued, choose a food-grade heat-resistant adhesive up to 300º.

Among other breakdown options.

Checking and cleaning the thermocouple. The oven burns as long as you hold the handle - then you need to check the fastening of the thermocouple. In the lowest position, it should touch the tongue. In case of incorrect placement in most models it is allowed to adjust with screws. It is possible that the thermocouple contacts are dirty and this interferes with the maintenance of the flame. Try sanding the part with sandpaper.

Broken "gas control" burners

If after cleaning the burner continues to go out, the fire burns, but is not fixed, the cause of the malfunction lies in the automation. It is possible to determine the state of automation using a multimeter. The thermocouple measures the voltage under heating. The solenoid valve is called for a broken winding.

6 reasons why the gas stove burner does not work.

We repair automation. "Gas control" is a set of parts working in pairs (thermocouple and solenoid valve). When heated, the thermocouple generates electricity to magnetize the valve. Loss of contact, as well as mechanical wear, will lead to a rupture, and the combustion of the gas will stop. It is easy to repair: we dismantle the table tray and securely fasten it in an upright position. A thin copper-colored wire from the burner to the gas stove faucet is called a thermocouple. The junction of the tap and the thermocouple is a contact.Separate the parts and clean the contacts with sandpaper, connect and screw securely.

Tip: If the gas control stops working, replace the thermocouple or solenoid valve. Install original spare parts according to the hob model. Universal parts differ in the diameter of the seats. The fit and installation height of the thermocouple plays an important role.
