Gas control of gas stove burners and ovens: what is it and why is it needed?

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.

Criteria for choosing a stove

Let's consider the features of gas stoves, which do not relate to their technical characteristics, but relate exclusively to the design.

The design, content, and arrangement of elements are no less important than the power or number of operating modes.

If you are interested in a device for seasonal use in the country, do not even go to the expensive equipment department - a portable stove with a connection to a gas cylinder will satisfy your needs and will last a long time

For continuous use, it is necessary to choose a reliable functional unit from a proven brand. To do this, you can read reviews and testimonials posted in large numbers on the Internet.

When purchasing from a design point of view, pay attention to criteria such as:

• dimensions of the stove in general and the hob in particular;
• oven volume;
• set of oven accessories;
• control panel location;
• location of the gas connection pipe;
• possibility of replacing burners for operation from bottled gas;
• number and sizes of burners.

Any unaccounted for detail may cause discomfort and dissatisfaction with the operation of the stove in the future, so try to think through everything in advance.

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:

1. 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.
2. 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.
3. 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.

Possible malfunctions in which the stove burner does not work

RemBytTech specialists repaired more than 2,500 (!) gas stoves whose burners did not light. In our experience, the breakdown is associated either with the gas supply or with a malfunction of the electric ignition system. The most common faults are collected in tables. This information will help you diagnose the stove yourself and find out the approximate cost of repairing the burner.

Failures related to the gas supply to the burner

Gas does not flow to the burner or for some reason is blocked by the gas control system.

Malfunctions associated with the lack of electric ignition at the burner

If there is a problem with the automatic ignition, the burner will light from a match, but will not turn on automatically.

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.

Adjusting the flame on the stove burners

It is necessary to debug the normal operation of the burner in cases where the flame loses its efficiency and quality. Setting up a gas stove should also be done by a specialist. But understanding the algorithm of this process will be useful for any user.

First, it’s worth understanding what a properly burning stove flame looks like. The fire should be blue. An intense bright blue glow is a sure sign that the stove is working correctly and does not need debugging. A yellow, orange or red flame indicates an incorrect composition of the combustible mixture. In this case, there is clearly not enough air; its flow must be increased.

Sparks and flame separation are another sign of insufficient air in the fuel mixture for the burner. The composition is corrected by working with a special screw

To change the gas-air mixture entering the burner, it is necessary to adjust the operation of the air dampers, which are usually located near each burner.

Direct setup goes like this:

• after disconnecting the stove from the gas system, it is necessary to gain access to the adjustment mechanisms under a special partition or in the gas control knob;
• the stove is reconnected to the main line, gas is supplied alternately to each burner;
• the volume of air entering the mixer is adjusted by turning a special screw;
• As soon as the flame in each burner acquires the correct color, you can turn off the stove again, reassemble it and connect it to the main line.

When setting up the stove, you may need to work with the gas control valve and its thermocouple. If the flame regularly goes out at a minimum fuel supply level, perhaps the problem lies in the gas control. The operating principle of this option is based on a special sensor that responds to the energy released during the combustion process. If the flame goes out unexpectedly, the thermocouple sensor cools down, signaling the gas supply to stop.

The simple operation of a small sensor can prevent terrible consequences. Therefore, the working surface of the stove and its parts must be kept clean.

However, oxidation processes and a decrease in the sensitivity of the sensor due to the ingress of liquids or the formation of deposits from food deposits can provoke incorrect gas shutoff outside of an emergency situation. Therefore, both the stove and this block should be kept clean, and if necessary, call a professional to clean it.

If you are faced with unusually noisy operation of the burner, we recommend that you find out the cause of the noise of the burner and how to eliminate it.

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 is gas control in a gas stove?

Any type of energy can pose a danger to human life. In this regard, protection has been developed that responds in a timely manner in the event of domestic emergencies:

• if the gas supply stops and the burners stop burning;
• the flame is blown out by drafts or food gets on the burners;
• accidental rotation of handles, for example by children.

Thermocouple

A thermoelectric converter consists of two pieces of wire made of different metals welded together. When this junction is heated, a potential difference arises, allowing current to flow.

Solenoid valve

Consists of an electromagnet with a core. Thermocouple current is supplied to the coil. The rod retracts, compressing the spring and ensuring an unimpeded flow of fuel.

Tap

The body contains a conical bronze bushing and a spiral. When turning the handle, it ensures a flow of fuel to the burners.

When a flame occurs on the burner, the thermocouple sensor located in the fire zone heats up. Due to the occurrence of a potential difference, current begins to flow through the conductors to the electromagnet coil.

A magnetic field is formed that affects the core. It has a flap. It retracts it, overcoming the force of the spring and ensuring free access of gas.

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:

1. Open the gas control system;
2. Disconnect the thermocouple - this is done with a key;
3. Remove the solenoid valve;
4. Remove the spring from the valve;
5. Insert valve;
6. If desired, attach a thermocouple;
7. Assemble the slab;
8. 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.

Operating rules

A gas stove is the main assistant in the kitchen of any housewife. But when using it, you must strictly adhere to certain operating rules:

1. If there is no electric ignition, the match is brought close to the burner and only after that the gas supply valve is opened. It is necessary to ensure that the fire burns in all burner holes;
2. The combustion should be smooth, without jerking, the flame should be blue or purple. If small flashes and extinguishing occur, it is necessary to check the burner - water or food residues may have gotten on it. If the flame is yellowish, with signs of soot, you should reduce the gas supply by turning on the burner;
3. The size of the cookware must correspond to the selected burner, the flames should not escape from under the pan;
4. Do not turn on the stove with the burners removed. In this case, gas combustion does not occur completely, which can lead to poisoning.

Important: before using the oven, you need to ventilate it by sharply opening and closing the door several times. This procedure will allow you to get rid of the gas accumulated inside if for some reason the tap is open or a leak occurs. Under no circumstances should you use a gas stove to heat a room, as this can lead to carbon monoxide poisoning.

Under no circumstances should you use a gas stove to heat a room, as this can lead to carbon monoxide poisoning.

It is very important to properly clean your household appliance. It doesn’t matter what your household gas stove is made of, whether it has built-in automation and additional protection against electric shock, before cleaning and other maintenance operations it is necessary to disconnect the equipment from the network.

In general, people are absolutely satisfied with their purchase - this is one of the best models on the market.

Lada 14.120-03 WH

Budget and small-sized model made in Russia. There is a grill mode with a power of 1.5 kW. Simple controls, excellent oven lighting, automatic ignition of burners and gas control - all these functions make the stove an excellent purchase for older people who need simple and understandable appliances.

Cost: about 7 thousand rubles.

Analysis of reviews : this model is popular due to its price, but the quality is criticized in the reviews - the iron is thin, the paint does not stick to the grates, the sides of the baking sheet are low. Rather, this budget option is suitable for a summer house or a rented apartment.

Gefest 5502-03 0044

Another stylish stove from Belarus. This time it's black. Oven with a capacity of 52 liters with grill, spit, convection and even steam cleaning. It will look great in a modern style kitchen. No deficiencies found.

Cost: about 24 thousand rubles.

Analysis of reviews : not everyone can quickly get used to the electric ignition of this model, but it is not complicated. Most reviews emphasize the appearance of the device. But they also notice some disadvantages, for example, the black glossy surface needs to be washed almost every day, because after cooking every spot is visible on it. The functionality of the stove is simple and reliable.

Darina S4 GM441 101 W

Another white classic model without any frills. But this time it’s worth highlighting a powerful grill - 2.6 kW - perfect for lovers of baked poultry or barbecue. Russian production. An excellent budget option with the usual dimensions for the kitchen. The switches are mechanical, but comfortable. The oven has double glass, but it’s large—you don’t have to open the door to look at the dish being prepared. No drawer for utensils.

Cost: about 10 thousand rubles.

Review analysis : users note that the instructions include a drawer for utensils, but in reality there is none. Since the model is budget, no complex things or functions are expected from it in advance, so buyers are satisfied. The only common problem is rust on the burners.

Gorenje GI 5321 XF

Gas stove from Slovenia with a huge 67-liter oven. There is gas control, auto-ignition and even an electronic timer separately for the hob and oven. You can highlight telescopic guides - the baking sheet itself moves out when you open the oven door.

Cost: about 34 thousand rubles.

Analysis of reviews : the main disadvantage of this model is the lack of a thermometer, so it is not clear whether the oven is warm enough to cook in it. Some people don’t like the fact that the electric ignition turns on on all burners at once, and not just on the one whose handle is turned. But these are trifles; the advantages like electronic separate timers and a thermostat outweigh. They are satisfied with the stove.

Gorenje GI 62 CLI

Another model from the Slovenian manufacturer with full gas control (both hob and oven). It is not made in the classic white color, but has an ivory tone, which is suitable for a classic interior, Provence and similar trends. The advantages include: timer, alarm clock, bottled gas nozzle and Aqua Clean cleaning.

Cost: about 33 thousand rubles.

Analysis of reviews : in this case, buyers agree that they are overpaying for the beautiful appearance of the stove, since it does not represent anything special in terms of functionality. 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.

Beware, scammers!

The work of Mosgaz is greatly hampered by scammers. They go from door to door, posing as gas workers, but their goal is to sell goods or services to gullible people at greatly inflated prices. And this is the first way to identify scammers - employees of Mosgaz JSC never offer paid services.

To understand that this is a scammer, you need to know what gas workers look like. One employee always goes to scheduled inspections, dressed in a dark blue uniform with orange inserts and reflective stripes, with the inscription “Mosgaz” and the company logo on the back. The employee has an identification card with a hologram, the coat of arms of Moscow and a seal; it indicates the number, position, name, surname and patronymic of the specialist, and a photograph is pasted in.

Now, due to the epidemiological situation, Mosgaz employees always wear masks and gloves. In addition, specialists have a protective suit with them, which they are required to put on if there is a sick person in the apartment.

Please note: how to distinguish a volunteer from a scammer

Tatyana Kiseleva says that the danger of scammers is not only that they deceive gullible people.

Tatyana Kiseleva emphasizes that scammers often wear similar dark blue overalls with inscriptions that contain the word “gas” - “Gazstroy”, “Gazkontrol” and so on: “Or they can call themselves Mosgaz. I called one of these people to ask how this happened. They told me that we are not Mosgaz JSC, but Mosgaz LLC. So you need to be very careful."

If there are doubts about whether there is a fraudster at the door, then you need to find out his name and surname, call 104 or the district's in-house gas equipment service and check with the operator whether such a mechanic really works at Mosgaz JSC and whether he should service this apartment today.

Basically, scammers take advantage of the gullibility of pensioners - they are good psychologists and know how to play on fears. For example, when offering some goods, scammers sometimes talk about cases of gas explosions that were recently discussed in the news, and may refer to laws, including non-existent ones. Elderly people are offered “discounts” that only pensioners can get and only today.

In 2022 alone, Mosgaz JSC received 4,830 reports of people walking around apartments and introducing themselves as gas workers. In January of this year, the Ministry of Internal Affairs uncovered a group of fraudsters that deceived more than 50 pensioners. According to Tatyana Kiseleva, the prosecutor is now checking several more groups of swindlers.

Thank you for the article. I was about to search the internet, but found it here in time and closed the other tabs. For one thing I learned that there is such a community here. I had a suspicion that there were capillary temperature sensors and I don’t understand what kind of gas opening drive, but everything turned out to be my favorite electric one, tomorrow I’ll try to restore one burner. A vague thought is still floating around: is it possible to somehow connect the timer with closing the gas? I’ll think about it, maybe I’ll invent something, I’ll post a mini-post here.

Please. What else is there a timer for? My method works, I haven’t disassembled the stove since the publication, but one burner is still stuck, I’m too lazy to disassemble it.

Well, here's my update: in our case, it turned out that the problem was not with the electrics, but with the electromagnet being faulty. I didn’t do anything further. They wrote here about disassembling the faucet, but this is generally difficult, to remove the faucet you need a 7 wrench, to disassemble it you need a 13 wrench (plus it doesn’t turn easily, I didn’t force the installed one), plus after moving the faucet on the gas the tube needs to be washed out, because... Even strong movement without removing it can cause a leak! I measured the current through this circuit, 100 mA through a heated thermocouple both on the working and on the faulty faucet. Let's re-post here the designations from the tap so that they are there. A 6489 CE 20703/179 I tried to look for a new one, several codes come up, the price is about 2 thousand, almost directly from Italy)) And, I must say, our electrics are clumsily arranged, the timer is not connected with the burners in any way, but I would like to sometimes set the shutdown time, because there is no multicooker. There is an option to increase the wiring of thermocouples, install “dry” normally closed relay contacts in each circuit, which can be controlled by a special circuit either from a piezo (then any sound will trigger it) or from a certain segment of the indicator (then only from a certain timer). But this is a fair amount of witchcraft, and even “dry” relay contacts can worsen this snotty design.

graphite lubricant. but it’s better not to smear anything there. I had it worse - at minimum heat one burner turned off. I had to disassemble the part where the connector is put on and bite off a couple of turns from the spring. Since then, everything has been working perfectly for 4 years.

I didn’t see any springs there)

did you understand? )) there is a simple electromagnet, when the sensor heats up, a current flows and the rod is attracted and opens the gas. when the heating current disappears, the rod is thrown back by a spring to its original closed position.

Now I understand what we're talking about. I don’t want to go there yet, it works. But thanks for the valuable thought

There’s a lot of bullshit in the comments, I’m tired of reading. Thanks for the report, that’s what I was guilty of. I'll do it one of these days. to bookmarks

You're welcome. I hope it helps

I have almost the same stove, the “ignition” has stopped working, what could be the problem?

I can't say it works for me

copper grease for calipers

Are you guessing or have you tried?

I didn’t try it on the stove, but I smeared the nozzle connectors on the car, everything is fine

gee. 1 Why the hell should I coat the connectors on the injectors with copper? 2 does not confuse the two orders of magnitude (TWO ORDERS) of voltage difference, and the order of current difference?

The contacts were burning. Pasta doesn't care about voltage

tension doesn't care about pasta! If a drawdown of 1 volt is not noticeable at the nozzle, then 1 tenth of a volt puts an end to flame control. no lubricants required! there you just need normal contact. All.

Damn, it feels like 90% of those advising thermocouples have only seen them in pictures. There is no need to lubricate anything there, do not spoil the equipment! and after annealing the thermocouple, you can most likely go for a new one.

check the thermocouple itself, you need a tester. voltmeter. on a cold thermocouple the voltage is 0 volts. when warmed up about 0.2 volts. The electric magnetic valve holds confidently at 0.1 volts. and at the same time, the current flows there is quite significant, therefore the contact must be excellent (ideally soldering or threading) and the test is simple: turn it on, warm it up, measure the voltage at minimum gas. The voltage is less than 0.1 volt, the thermocouple is more and the gas control does not work, bad contacts or electric solenoid valve.

Nuances

The mode and operating principle of gas control has some nuances:

• For each ignition, you need to wait 15–20 seconds until the required temperature is reached.
• If the ignition time increases, it means that the electric couple is clogged or dirty.
• It is unacceptable to independently change the operation of the system in an attempt to reduce the ignition time.
• The reason for lack of ignition is not always the gas control sensor. Sometimes fuel may not flow into the burner due to clogged holes.

To avoid problems and fines, be sure to call a professional if there is any problem with your gas equipment.
