Many apartments and houses still have gas stoves. Most often, owners have no choice, because if there is a gas pipe, then an electric stove may simply not be suitable due to high electricity consumption.
However, gas is a dangerous substance, and its leakage can lead to catastrophic consequences. But manufacturers think about safety, so almost every modern stove has a gas control system. Let's look at what it is - gas control of burners and ovens, how it works and whether it is worth buying a stove with this option at all.
Design and principle of operation
The essence of the gas control is extremely simple - if the fire is extinguished by something, accidentally or not, then the gas stops flowing to the burner, thereby preventing its leakage and accumulation in the apartment. The most popular reasons for the unintentional extinguishing of a fire are considered to be a draft or boiled-over liquid.
But how does the system figure out that the fire has gone out? In fact, the gas control device is extremely simple. The main part can be called a thermocouple - these are two fused metal wires from different materials, the end of which is led to the burner, namely to the fire.
When you turn the stove handle, the fire turns on, the wire heats up and creates an electromagnetic field - this is the basis for the operation of the gas stove thermocouple.
This field affects the magnet to which the handle of the plate is connected. The magnet acts on the spring, opening the gas supply valve. If the fire suddenly stops, the wire will no longer heat up and, therefore, create an electromagnetic field. The gas control valve will simply close without the action of the magnet and the gas supply will stop.
If this happens, then simply repeat the ignition. It will take 5 to 20 seconds for the thermocouple to heat up again. All this time you will have to hold the burner knob in the desired position, otherwise the cold thermocouple will extinguish the flame again.
If previously the thermocouple was connected as a whole to the hob, now it is connected separately to each burner. If one burner stops working due to a breakdown in the gas control system, the rest will be able to cook dinner.
The device is quite simple, but proven, so malfunctions occur extremely rarely. It is also important that the operation of the gas control is completely autonomous and does not require electricity - this will ensure uninterrupted protection of the apartment even when the lights are off.
What to do if the gas control of the stove does not work
If a gas oven is equipped with gas control, then there will be a corresponding sensor near each burner. It contains an electric couple - a mechanism that converts heat into electricity. When the burner is ignited, the sensor heats up, the resulting thermal energy is transferred to the valve and opens the gas supply tap. If the fire goes out, the sensor will cool down and the valve will close due to loss of energy.
This function is useful for ovens without automatic ignition. In budget models, to start the oven you need to remove the tray, open the feed valve and simultaneously light it. After this, the door is usually closed to allow heating. It is not always possible to clearly see the flame in the oven. Therefore, if you are concerned about your own safety, it is better to buy a stove with a gas control function.
Advantages and disadvantages
The main advantage of gas control is safety. News reports often contain reports of gas explosions in residential buildings. All of them could have been prevented if the stove had a working gas control system.
This option is especially useful for families with small, inquisitive children or elderly and slightly absent-minded parents.
The gas control system allows:
- relax a little and don’t sit in the kitchen all the time cooking to watch the fire;
- prevent accidental gas leaks, and therefore explosions, fires and poisonings;
- provide protection from children who like to twist the handles. When you press it briefly and release it again, the gas stops flowing. Usually the child is not able to hold the handle in one position long enough to allow the gas to turn on.
But such a system also has negative sides:
- The first thing people complain about is how long it takes to turn on the burner. The fact is that the thermocouple sensor does not heat up instantly, so the knobs must be held for about 5 seconds before the gas control starts working. If the stove is old or not properly maintained, this time can be increased to 20 seconds.
- The second negative point is related to the fact that the gas control is a device made up of several parts. This means that it may break, malfunction, or simply not work. This is quite rare, but still occurs. Replacing or repairing this system yourself is not so difficult, but it is dangerous and prohibited by law.
- The third common complaint from people is that the gas control is activated even on a small fire and turns it off. That is, it will not be possible to simmer the porridge over low heat, since it will constantly simmer. This is not a completely correct situation - ideally this should not happen. Most likely, we are talking about loose thermocouple contacts, so it is better to call a technician.
A separate category of people is based on the fact that previously there was no gas control in the stoves, and everyone lived somehow. In their opinion, this option only increases the cost of the gas stove. In fact, the prices for equipment without and with gas control are approximately equal. The difference of a couple of thousand rubles is completely incommensurate with the security that this system provides.
How to determine a breakdown?
Usually, if we are talking about a breakdown of the gas control, this becomes immediately obvious, since the hob simply will not work. In this case, they most often talk about a broken thermocouple. A failed thermocouple is considered a potentially dangerous breakdown and therefore requires immediate repair.
But there are also a number of not so obvious signs that will help identify the problem. These include:
- the fire goes out for no reason during cooking;
- the fire goes out after lowering the handle;
- the fire ignites after a long time interval after turning on the stove;
- when the flame is blown out, gas still flows;
- gas control of the oven turns off the flame during operation;
- the oven does not turn on;
- other malfunctions or malfunctions of the mechanism.
Causes
It is important to understand why the gas control system may fail.
If we are talking about a long time to ignite the fire when turning on the stove, then most likely the problem is a dirty thermocouple. Someone solves this problem by simply fixing the handle in the required position so as not to hold it manually.
It is better to eliminate the problem itself and call a specialist for this. If you have the skills to repair electrical equipment, then you can do it yourself - simply by removing the hob and cleaning the heating element.
If after this the problem does not disappear, then we can talk about a malfunction of the gas control system. It could be:
- solenoid valve wear;
- displacement of the thermoelement relative to the flame;
- stupor of the burner tap;
- bad contact.
There are also possible more distant reasons for the unsatisfactory operation of the stove - for example, insufficient gas pressure. It can be caused either by problems at the gas distribution substation or by a gas tap in the apartment that is not fully open.
If the problem is in the tap, then you just need to open it all the way. If the reason is in the substation, then you will have to submit an application to the local gas department.
There are few options for what to do if the gas control breaks down. It is best to immediately contact a specialist, since independent repairs are prohibited.
What to do if the gas control of the stove does not work
Gas control (or, as more than 2 times fewer people write, gas control) of most, if not all gas stoves, works on the same principle: we have a thermocouple located near the corresponding burner. When the fire burns, it heats the thermocouple and it begins to produce electricity - only 30 millivolts, which are transmitted to the solenoid valve installed between the main gas line of the stove and the gas regulator of this burner, which is closed by default, but opens when the above voltage is applied to it .
In many modern stoves, for example, Gefest, where gas control is built into all burners, pressing the gas control knob itself opens the gas control valve, so after the gas ignites, the knob must be held down a little, and not released immediately, so that the thermocouple ignites The burner had time to heat up and the gas control valve began to be held in place by the current from it.
The handles of the gas taps of the burners here turn without pressing, and the gas control here is installed only on the upper and lower burners of the oven, therefore, in order to light them on such a stove with a properly functioning gas control, we need:
- Turn the gas regulator in the oven to maximum (or set it to the “top burner” mode). In this case, gas should not flow.
- Light a match and bring it to the desired channel at the bottom of the oven or to the top burner.
- Press the red gas control button, which will open the gas supply valve, it will flow into the burner and it will light with a match.
- Keep the gas control button pressed until the thermocouple heats up and the solenoid valve “seizes” from the current it produces.
- Release the button, it will come back out, because... spring-loaded, and the gas will continue to burn as if nothing had happened.
Moreover, if you turn off the gas after this and immediately try to light it again, you will no longer have to press the button: heating the thermocouple is enough for 10-15 seconds to hold the gas control valve open, after which it snaps back quite loudly, cutting off further gas supply.
Here is such a simple scheme. But what should you do if the gas control on your oven does not work as it should, the gas goes out spontaneously and you cannot bake or cook anything normally? Let's figure it out, let's move on to diagnostics!
If the gas control of the stove does not work, the first thing you need to do is contact a service center that repairs gas stoves and other gas equipment. It is better to repair the gas control system by professional technicians. Independent intervention in the operation of the stove without original spare parts will push you to turn it off, which can lead to disastrous circumstances.

Is it possible to turn off the gas control yourself?
Correct and safe installation, connection/disconnection and even operation of gas stoves rest on the shoulders of apartment owners and tenants. This responsibility is spelled out in the Civil Code of the Russian Federation, in Article 210.
If you want to turn off gas equipment without permission, you must read the document called “Building Codes and Rules for Gas Supply 2.04.08-87.” It says in black and white that it is necessary to call a qualified specialist with a certificate from the Gas Inspectorate and a certificate.
You can try to disable the gas control system yourself only if you have already had experience in repairing similar devices, and their structure seems familiar.
The most important thing to do is turn off the gas supply. In addition, it is important to follow the following safety rules :
- completely de-energize the kitchen and remove all self-powered appliances - even smartphones;
- open the window wide;
- turn off the tap on the gas stove and unplug the appliance from the socket;
- put a plug on the pipe;
- check the quality of the plug using a soap solution - it should not bubble;
- If the solution bubbles, there are whistling sounds or a smell of gas, you must urgently call emergency services.
After that:
- Open the gas control system;
- Disconnect the thermocouple - this is done with a key;
- Remove the solenoid valve;
- Remove the spring from the valve;
- Insert valve;
- If desired, attach a thermocouple;
- Assemble the slab;
- Check the quality of the connections with a soap solution.
How to turn off the oven gas control. How to do it directly at GEFEST
The procedure does not look complicated, but you need to understand that there is interaction with an explosive substance. If such repairs are discovered, the regulatory authorities have the right to impose a fine.
If a person considers the gas control function unnecessary and wants to disable it, then it is best to call a specialist who will carry out this procedure. After this, the controller must make entries in the device operation book indicating the date and reason for this procedure.

It works well, but there are also minor flaws - for example, the grate is not quite level, the oven door is not closing quite smoothly, and so on.
Gefest 3200-08
Another Belarusian stove. It is distinguished by good quality and budget price, which determines the enormous popularity of this model. It has a small width of 50 cm, so it will fit even in the smallest kitchen, but for a large family it may not be very convenient. One burner has a quick heating function. There is a drawer for dishes. An excellent classic model without unnecessary bells and whistles.
Cost: about 9 thousand rubles.
Review analysis : buyers note that this is the best budget model on the market. But there are also small drawbacks, for example, for some, after two months of active use, the handles begin to turn tightly - you need to make an effort. Some people find the grate slippery because pans and pots roll around. The main reviews of this stove from Hephaestus boil down to the fact that the stove is simple but reliable.
In reviews, many tell stories about how gas control came in handy. For some, children were simply playing, for others, elderly parents set the soup to cook and forgot. After stories like this, they have no questions about whether gas control is needed in a gas stove and oven or not.
Gas control in a gas stove - what is it?
There are buyers who, when they see the word “gas control” in the passport of a product, do not understand what it is, what it is for, and whether it is worth overpaying for it. Gas control is an auxiliary safety system designed to prevent gas leaks. Its presence protects against the risk of unfavorable situations such as an explosion or fire, which can cause varying degrees of damage or even kill people. Basically, this is a device built into the stove that stops the gas supply if for some reason the fire goes out.
In previous models, the device was mounted on the entire stove. Some of them still exist. Now the burners and oven, each of them, are equipped with an individual sensor. This makes it possible not to completely deprive the entire unit of gas, but to prevent its flow to just a separate element. Using this privilege, you can leave the stove while preparing food and not worry about emergency situations.
Important! The presence of a stove with gas control makes it possible to somewhat relax your attention to the progress of cooking, but does not allow you to leave the device for a long time completely without supervision, much less leave the apartment, leaving the stove on.
