Why the gas stove does not hold the flame, the oven goes out and the burner goes out: an overview of the causes and repair tips

self-repair

Almost all users make attempts to repair equipment with their own hands. At the same time, they often do not even think about opening the instruction manual. Without knowing which boards and design components are used by the manufacturer, you can damage individual elements, although they previously worked properly. In order not to increase the complexity of the repair, it is better to immediately contact the specialists.

In addition, in attempting repairs on your own, you take full responsibility for the incorrect installation of the stove, as well as the tightness of the connections. Wrong actions lead to the fact that the gas begins to seep through microscopic holes, and poison everyone in the room.

Common causes that you can solve yourself

Most housewives still opt for a gas oven when choosing kitchen appliances. They are distinguished by wide functionality, precise settings and simple operating conditions. Despite all the conveniences, when working with this device, a problem may arise - the oven goes out after a short period of switching on.

There may be several reasons for this:

• lack of oxygen;
• the gas supply valve is closed;
• slow heating of the flame sensor;
• pressure drop in the pipeline;
• burner contamination;
• incorrect installation of the burner after cleaning.

These factors can be solved independently. The process of work does not require specialized skills, and also does not take much time.

Solving the problem yourself:

1. Insufficient oxygen supply can cause the oven to go out. In such situations, experts recommend lighting the oven with the door open.
2. By inattention, you can forget to turn the valve to open access to the incoming gas. It is recommended to check if the turntable for gas supply to the stove is open.
3. For safety reasons, gas stoves with built-in ovens are equipped with additional flame sensors. This device detects the absence of an increase in temperature and shuts off the flow of gas.In such situations, you should hold the power button a little longer than usual. It will be useful to turn on the oven at the maximum temperature. This step will help speed up the warm-up. This situation is faced mainly by residents whose houses are equipped with bottled gas. Due to the low intensity, the sensor does not warm up, which leads to its shutdown. To solve the problem, it is necessary to change the cylinder to a full one or refuel.
4. In the process of cooking various dishes, droplets of fat and small particles of food fall into the holes of the burner, which gradually leads to its failure. This is easily noticeable visually: the burner ignites unevenly, with frequent interruptions, in some areas there may be a complete absence of fire. In this case, it is necessary to carefully remove the burner and carefully clean its surface from the formed soot.
5. After cleaning and washing, there is a risk of incorrect installation of the burner in the cavity. The signs here are similar to the previous factor: uneven flow of flame or its complete absence. If this is the reason, the burner must be removed from the installation area and correctly inserted into the cavity.

Fan failure

The cooler provides cooling for such important microwave components as the magnetron. When overheating occurs in the stove, a temperature relay is activated, which stops the operation of the cooler.

Also, the fan stops functioning if it has the following breakdowns:

• The cooler motor is broken. It cannot be repaired, so it will have to be replaced with a similar model in terms of power and external parameters.
• The cooler bearing broke, a ball pops out of it. If the bearing housing is cracked, it needs to be replaced.The popped-out ball can be inserted back and the device will serve you further.
• One of the blades is deformed or completely broken off. In this case, the microwave cooling efficiency decreased. Repair consists in replacing a part.
• Particles of food, drops of grease and dust stuck to the rotor. This was supposed to interfere with the normal operation of the apparatus. It needs complete disassembly and further cleaning.

The main reasons for extinction

Among modern plate manufacturers such as Veko, Hephaestus, Indesit, Darina, it is difficult to single out a leader, since the equipment from each of them is quite in demand among consumers. But sometimes, during the operation of a gas oven, the flame may go out, which causes indignation among the owner of the unit.

This is why the oven in the gas stove goes out during operation:

• premature release of the control knob;
• the thermocouple is burned or worn out;
• the solenoid valve is out of order;
• the oven thermostat has decalibrated;
• the oven door is too tight;
• the thermocouple is mounted above the flame;
• the connection in the gas control system has loosened;
• the flame smokes (gas burns incorrectly);
• the thermostat of the oven has become faulty;
• the gas valve is stuck.

Thus, the fire can go out due to many reasons. However, of all users of modern technology from Veko, Hephaestus, Indesit, Darina, the owners of Hephaestus stoves most often complain about this problem.

Oven bottom

Why does the oven go out in the Hephaestus gas stove

Often there is a problem of the disappearance of fire after releasing the handle regulating the gas supply. However, this does not cause such inconvenience as the disappearance of fire right in the process of cooking. Especially often this trouble haunts the owners of the Hephaestus gas stove.Why does the Hephaestus gas oven go out during operation? Most often, the problem lies in the built-in gas control.

Oven repair

Handles don't turn

A fairly common problem is the inability to turn on the equipment due to the fact that the fuel supply knobs do not turn. There could be 3 main reasons for this:

• adhering grease and dirt prevent turning;
• dried grease on the faucet;
• element breakage.

You can fix the problem with contamination and lack of lubrication yourself, but if you do not know the design of your device, and which lubricant is better to use, then it is better to call the master.

If the handle turns with great difficulty, then you should not try to turn it through force, perhaps a small object has fallen between the body and the plug, which interferes with the stroke of the stem. You can eliminate the defect when disassembling the device, and in order to avoid such an annoying phenomenon in the future, it is necessary to carry out preventive measures.

Sometimes the opposite problem occurs, when it is not possible to light a fire due to turning the handle 360 ​​°. This usually occurs on devices during long-term operation. The reasons are loose seats in the handle, unscrewed screws of the crane holder, disconnection of the stem and studs. Such problems are eliminated by replacing parts and returning them to their original positions.

Why does the electric ignition on the hob not work?

Increased dampness inside the panel. Excess water that got inside the structure after heavy washing or boiled food can create increased humidity. As everyone knows, water is a good conductor of electricity, therefore, getting on the contacts of the power button, it closes them and thereby activates the electric ignition of the hob.What to do in this situation? Such a malfunction is not dangerous for residents, it cannot lead to irreversible consequences, the only thing that constantly clicking is crazy. As soon as the water evaporates, the clicking of the hob will immediately stop, so to help the water evaporate, turn on the oven for 30 minutes or turn off the stove for 2-3 days. Wipe the stove burners and the entire worktop dry before taking these steps. If the problem persists after the expiration of time, you should contact our repair shop and order
hob repair.

Fat and food on control buttons. Grease that has accumulated over time on the electric ignition buttons can jam it. In the design of the button for opening the contacts, a conventional metal spring is installed, which, when the handle is released, returns to the primary calm state. Fat that has got into all the slots of the button slows down the sliding mechanism and it is difficult for the spring to overcome such tension. Repeated switching on can lead to jamming or complete breakage of the button. If the ignition lock breaks, the electric igniter will continuously generate an electrical spark - even after the burner has ignited. In this situation, only a qualified person can help you.

Faulty ignition unit. Like all household appliances, the hob has its own service life. With prolonged use, natural wear of parts appears, for example, over time, the electric ignition unit may close, which leads to a constant clicking of the hob.In this situation, the right decision would be to invite a master to the house for
electric ignition repair
, or rather, the replacement of the entire block.

Cleaning and prevention

1. Clean the surface of the plate from food debris after each preparation of food, waiting for the plate to cool down.
2. Do not leave the switched on stove unattended, as the boiling liquid from the containers floods the flame of the burners, which leads to premature wear of the auto-ignition and gas control systems.
3. Do not forget to lubricate the rubbing surfaces of the adjusting knobs.
4. Cleaning of burners, jets, junctions of regulators and switches is carried out with a needle or thin wire, metal brushes and brushes are also suitable.
5. Perform periodic maintenance. To do this, the protective panel is dismantled, the studs are removed, the rods are pulled out, the parts are cleaned and inspected for mechanical damage and signs of wear. The mating and mating elements are lubricated with graphite grease.

The hob is becoming more and more common in the modern kitchen due to its convenience, enhanced functionality and improved appearance. We talked about the signs, causes of malfunctions and self-repair of hobs in our materials. You may find our experts' advice on how to repair induction cookers, timers, oven doors, electrical appliances with ceramic and glass-ceramic surfaces, and electric stove ovens useful.

Repairing a gas stove seems to be a difficult task. Armed with the necessary tools and troubleshooting instructions, you can repair household appliances yourself and save a significant amount of money.

Other Sources of the Problem

Consider other issues causing fading problem columns after ignition.

The fading of the wick may be due to the presence of powerful ventilation near the column. Exhaust air is drawn into the ventilation, which leads to attenuation. It is necessary to turn off the ventilation or turn its power to the minimum for the duration of the gas heater.

For the same reason, you should not place a powerful hood next to the column. During its operation, sensors may be triggered, diagnosing a malfunction.

Sometimes the reason is hidden in the absence of natural ventilation. It is necessary to open the window or install a supply valve.

The extinguishing of the wick can also occur in models with piezo ignition. The button must be held for at least 10 seconds.

"Smart" geysers may not ignite due to a burned out control board. They are sensitive to the quality of the electricity supply, so they must be connected through a stabilizer and not turned off at night

Also, during the operation of the heater, it is not recommended to mix hot and cold flows. This leads to a drop in pressure in the line and attenuation of the wick.

The problem is solved by adjusting the indicators to a comfortable level and reducing the pressure with a special handle. If you still have to mix water, you need to leave the main hot stream.

Attenuation can cause a malfunction of the solenoid valve or servomotor. Only calling the wizard will help here.

The design and device of the plate

All gas stoves are arranged in approximately the same way. Below the plate top you can see the following structural elements:

1. Burners. They are attached to the plate with strong bolts. In this case, each burner is decomposed into its component parts - a divider, an injector and covers.To have access to them, it is necessary to disconnect the copper or steel pipe attached to the base of the burners. This will require a key for 13.
2. Candles. Located around the perimeter of each burner. One is for ignition, and the other is used as a thermocouple. They are different from each other, so you can easily find the right candle. High-voltage candles are covered with a ceramic caftan.
3. Collector. This is a thick tube from which wiring is supplied to each burner. When the flame of one of them is extinguished, the rest will continue to work.
4. Distribution armature. Each ignition electrode is connected to single high voltage wires.
5. Capacitor, thyristor, diode and fuses. These details are located inside the plate. They work when the charge needs to be formed due to a surge of energy from a candle.

Why does the oven go out after releasing the handle

Reason #1. Thermocouple defective.

Today, most gas ovens and ovens use an automatic control system that makes them safe to use. One element is a thermocouple that attaches to the fryer bracket. burners at a distance of 147 mm from the vertical axis of the burner.

The gas oven is turned on by pressing and turning the tap handle. Electronic ignition ignites the burner where the thermocouple is located. The thermocouple is directly connected to the solenoid valve by a threaded connection. When heated, the thermocouple generates a weak voltage to magnetize the valve. The magnetic field keeps the valve open and gas flows to the burner.

If the tip of the thermocouple burns, the valve will instantly shut off the gas supply, so if the gas oven does not work after releasing the handle, the faulty thermocouple of the gas control system is to blame.

Reason number 2. Thermal solenoid valve defective.

The second element of the security system. Its purpose is to stop the gas supply to the burner in case of violation of the operating rules. The valve consists of: electromagnet, winding, bottom valve.

When the handle is pressed, the lower valve rests against the plate of the upper valve, as a result of which the gas is directed to the burner in the oven, where the thermocouple is ignited and heated. The resulting EMF from heating the thermocouple returns to the valve, where the electromagnet is able to be held open. If the valve has received mechanical damage (violation of the winding insulation), the valve will move away from the seat and shut off the gas supply.

OR, WE TRY TO CLEAN THE CONTACT

To a greater extent, the gas in the oven goes out due to poor contact between the thermocouple and the valve.

For this:

• We open the cooking table of the stove;
• Disconnect the thermocouple from the valve.
• We clean the contact with sandpaper and degrease.
• Screw the nut back.

Why does the flame go out in the oven?

In a gas oven, the flame goes out immediately after ignition or during a short operation for the following reasons:

• The gas regulator does not work. The oven cannot be ignited.
• Strong fit of the oven door. This leads to air deficiency during combustion. And as a consequence, the gas decays already during operation.
• The thermocouple is out of order or burnt. If, after stripping, it does not return to working condition, then the part must be replaced.
• The temperature sensor has left the flame zone.Restoring its position will return the oven to operation.
• The solenoid valve is defective. Parts need to be replaced.
• The thermostat has stopped working. The master will be able to adjust his work or replace.
• The contacts in the gas control system are oxidized. It is necessary to strip the contacts, and reconnect the circuit.
• Faulty thermostat. It needs to be replaced.
• Smokes a flame when burning.

It should be recalled that the gas is a potentially hazardous substance. And the repair of gas equipment should be carried out only by a specialist who has a special permit for this type of work. For repair, in addition to knowledge and experience, special equipment is also needed. Do not try to repair the gas stove yourself. This can lead to even greater damage and irreparable consequences.

Main causes of malfunctions

If your gas oven stubbornly refuses to work, do not panic. Most of the problems can be fixed and the operation of the device can be directed in a good way. The main thing is to accurately determine the cause of the trouble.

Practice shows that ovens fail for the following reasons:

• thermocouple failure - natural wear or simple burning;
• solenoid valve wear;
• thermostat calibration;
• the door does not fit properly;
• stuck gas valve;
• the connection in the gas control system is broken;
• broken oven thermostat.

Any item from this impressive list is eliminated with the help of a professional master. It is almost impossible to carry out repairs without specific skills, so it makes sense to take care of finding a good specialist.First, an accurate fault diagnosis is required. Please note that a number of spare parts will be required. Independent search is a troublesome and time-consuming task. But, with experience and time, you can handle it yourself and look for a good dealer selling spare parts for household appliances.

Some experts offer home oven repair services

Caution does not hurt here, as unscrupulous businessmen invent a number of non-existent breakdowns

Gas oven goes out due to a faulty thermostat

The correct operation of the thermostat is very important, since the entire cooking process depends on it.

The thermostat provides gas supply to the main and frying burners of the oven and maintains the desired temperature in the oven by increasing and decreasing the gas supply inside the oven. If the oven starts to cool down, the thermostat will increase the gas supply, thereby increasing the heating. If the temperature in the oven reaches the set value, the thermostat reduces the gas supply to maintain a constant temperature. One of the malfunctions is the lowering of the flame to an unacceptable level, which leads to a cooling of the thermocouple and to an emergency shutdown of the oven.

Did you know that after 10 years, the gas in the oven can go out due to poor ventilation. Carbon monoxide accumulates and extinguishes the burner. Move the stove away from the wall by 5-10 centimeters, remove the towels from the handle. Wash the rear wall of the stove and the ventilation duct from grease.

Troubleshooting a Gas Stove

Typical malfunctions for each brand of gas stove, as well as the “weak points” of a particular model, we painted in the relevant sections. For more accurate information about breakdowns of a gas stove of a certain brand, follow the links ..

Before attempting to repair gas column malfunctions, make sure that there is access to gas and electrical communications (batteries are changed and all taps are open). We often come across customers who complain: “I open the water tap, but the column does not light up”, they call the craftsmen and pay money as if for a good overhaul, because they do not follow and do not know the simple operating rules that are described in the instructions.

1. Gas stove burner does not ignite or turns off. A common malfunction of the gas stove and hob is poor switching on or not turning on the gas burner at all. This malfunction can be caused by the usual clogging of the nozzle with food particles; crack or insulation failure on the spark plug; broken solenoid valve or burnt thermocouple. If your stove is equipped with automatic ignition, it is worth checking the presence of current in the electrical network by turning on another device.

2. The stove's gas burner goes out during operation. If the gas burner of the stove goes out during operation, it is worth observing the combustion of gas. The flame from the burner should wash the thermocouple from all sides. If the fire does not reach the thermocouple, clean the stove nozzle: - otherwise, the gas supply will need to be adjusted. If the above steps do not help, you will need qualified assistance to deliver and replace the burnt thermocouple.

3. Electric ignition does not work (does not click, there is no spark) This breakdown is not a sentence for the panel, most owners switch to matches. Cause of occurrence: lack of voltage in the network; the spark generation unit (ignition unit) burned out; the contacts of the power buttons are oxidized. Troubleshooting begins with checking the outlet.Plug a known-good appliance into the outlet. Contacts are visually inspected, if necessary, cleaned with alcohol. If these manipulations did not help, change the ignition unit.

4. The gas burns weakly (the burner may not turn on). If the flame on the gas burner burns sluggishly than usual (has a small corona), the cause of the malfunction may be a clogged hole in the atomizing gas jet. The burner needs to be thoroughly cleaned. The height of the flame directly depends on the amount of fuel and air supplied to the burner. Adjusting the air damper and cleaning the nozzle can correct the problem, but this work should be done by a specialized technician.

5. Stove burners burn badly (smoke). If the flame on the gas burner burns sluggishly than usual (has a small corona), the cause of the malfunction may be a clogged hole in the atomizing gas jet. The burner needs to be thoroughly cleaned. The height of the flame directly depends on the amount of fuel and air supplied to the burner. Adjusting the air damper and cleaning the nozzle can correct the problem, but this work should be done by a specialized technician.

6. Gas control valves are difficult to turn. To a greater extent, it is due to the sticking of fat on the rotary mechanisms (adjustment knob and plastic rings). Remove everything and wash with soapy water. To a lesser extent, it is due to the lack of lubrication inside the tap. You should disassemble the faulty faucet, clean out the old graphite grease and apply a new one. Do not overdo it with the amount of lubricant, otherwise, over time, the faucet holes will become clogged with excess.

8. The smell of gas.The smell of gas during cooking or at the end indicates that the gas stove requires maintenance. If you feel the presence of gas near the stove or in the room where the kitchen appliance is installed, immediately turn off the tap on the descent to the stove, open the windows and ventilate the room. Very often during repairs, we notice that a gas leak comes from a poor-quality connection. In the future, entrust the installation to trusted organizations. Such a malfunction of the gas stove is difficult to fix with your own hands, contact the gas service for help.

9. The burner turns off when the handle is released. Modern imported gas stoves are constantly “suffering” due to the poor performance of the gas control system. The thermoelectric valve often breaks. We recommend that you do not try to repair it, let alone turn it off, the right solution would be to replace the worn valve with a new one. Gas control is, first of all, your safety and the safety of your property.

Types of ovens

There are two types of ovens: gas and electric. In the entire history of the existence of gas ovens, their equipment and principle of operation have not changed dramatically. Therefore, their main difference from each other is the volume, design and brand of the manufacturer. The difference between a gas and an electric oven is that a gas one heats food from a maximum of two sides, since here the heating elements can only be located from below and from above. happens evenly.

Troubleshooting Options

If the control system fails, it is necessary to replace its components: thermocouples or valves. In some situations, a complete replacement of the entire system is required.
If the thermostat malfunctions, the heating level decreases. For stable operation, its calibration and timely diagnostics are necessary. When broken, replace.
In the process of prolonged use, the handles fail. In this case, it needs to be replaced.

When buying, pay special attention to the identity of the new part. It is easy to replace it yourself: gently pull the old handle towards you, it can be easily removed

We fix a new part, check the oven.
In most cases, to fix the last problem, you need to disassemble the gas valve, clean it completely, and lubricate it with special grease. In some situations, it may be necessary to change parts. In this case, it is better to turn to professionals.

The stove goes out after turning on the oven, fix

It happens that the hob of the electric stove works quite well, but immediately goes out as soon as the oven is turned on. There are not so many reasons for this behavior of technology, and I will discuss all of them below.

The oven itself is defective

Simply put, the oven closes, which knocks out the machine, so the entire stove does not work. The reasons for a short circuit can be different and more on that later. If this happens, the device is immediately disconnected from the network. Next, you need to check the wiring for damage.

Poor contact insulation

This leads to contact between the contacts or in a certain area with the metal parts of the case. It is necessary to repair the insulation or replace the wires. For a complete check, it is worth examining the condition of the insulation and the contacts of all wires, including those with a power switch, a backlight cartridge.

Worn wiring on heating element

Most often, during long-term operation, a burnt out phase wire comes off the heater. It contacts the metal case, as in the previous case, this leads to a short circuit. The solution is stripping and fixing the wire on the heating element. It makes sense to check all the wires going to the oven heater in order to avoid a recurrence of the problem.

Additionally, you can check the heater itself for a breakdown, it may be damaged itself. In practice, it happens that the cause of problems is improper storage of equipment. If condensate gets on the heating elements and they are wet, the stove will turn off. Usually, the heaters are dried, for which they turn on the device for about five hours.

Faulty control module

Electronic filling with control functions is an essential attribute of almost any electric stove. If there is a malfunction, this also leads to a short circuit. Repair comes down to replacing the old module with a new one, which should be entrusted to a specialist.

Something is wrong outside the stove

The surroundings of the device are also full of electrical things that can break under certain favorable circumstances.

The machine in the apartment is not designed for the load that the oven creates

A familiar picture is observed here - when the oven is turned on, the machine knocks out and the entire appliance does not work. The problem can be much wider: incorrect connection of the plate, especially the terminals, incorrectly selected power cable. It makes sense to check exactly how the equipment is connected with a reference to the instructions in the operating instructions.

When everything is normal for this part of the installation, it is necessary to install a more powerful machine. Although this does not always help, after all, an electrician is a delicate thing.

You may have to pull a separate wiring, since the old one in terms of material and cross section does not match the power of the device, and install an additional machine for the stove.

A more powerful device does not always save, in addition, under other circumstances, such a step can lead to sad consequences. In general, it all depends on the situation. Contact an experienced electrician.

I note that sometimes even the most powerful switch works out its service life and ceases to hold its nominal current. Here, too, only a replacement will save.

leakage current

Current leakage cannot be ruled out. This point can be verified. The total leakage current almost always causes the machine to operate, due to which the stove refuses to work.

There are three possible options here:

• if the leakage current is higher than 16 mA (I remind you that in everyday life it often happens that the minimum tripping differential current on the RCD with the installation is designed for 30 mA), you need to dig towards the faults of the oven itself, which I mentioned above;
• there is a current below 1 mA - we change the machine without unnecessary ceremonies;
• if 5-10 mA, you need to sort out the oven and change the RCD.

What is the result

In such a situation, three options emerge: either a complete overhaul of the stove with the help of a professional electrician, or its replacement (if the warranty has not expired), or a direct path to the official service.

I don’t advise joking with electricity - if, after turning on the oven, it cuts down the entire stove, measures must be taken immediately.

I note that among the whole heap of possible causes, most often the source of problems is bad contacts, poor connection, damage to the power cord, broken ground wire, and so on, this is where you need to steer in the first place.
