Gas control device for a gas stove - how to turn it off and how dangerous it is

Gas stove with gas control function: purpose of the system

What is it - gas control of the oven and burners in a gas stove? This is a function that prevents gas leakage and allows you to protect a person from a fire or explosion.
Function purpose :

• automatic shutdown of gas supply in case of flame extinguishment;
• there is no need to closely monitor the cooking process;
• prevention of explosions, fires, poisonings;
• providing the user with peace of mind even in emergency situations.

These are the main advantages of the system. But it is not without its drawbacks :

• unstable operation of the stove in case of system failure;
• complex repairs;
• long ignition of the burner.

In early models, the function was installed on the entire stove . In modern devices, each burner and oven are equipped with their own sensors, due to which the supply of flammable substances is stopped selectively, and not immediately to the entire stove.

Reference. Popular models with built-in gas control include De Luxe 506040.03g, Gorenje GI 5321 XF, Gefest PG 5100-04 002.

Operating principle

The design of the control system for the burners and oven of the stove consists of several elements:

• thermoelectric converter (thermocouple) - two connected wires, which are made of different materials and connected to the valve;
• solenoid valve - a device that shuts off the supply of a flammable substance in the event of a sudden extinguishment of the flame;
• flame sensor - a thermoelement placed at the fire level.

The principle of operation is based on the joint and sequential functioning of all elements of the system and looks like this:

1. Pressing, turning and holding the knob on the panel with built-in electric ignition opens the gas supply and lights a fire on the stove burner or in the oven.
2. The flame heats the thermocouple.
3. The thermocouple transmits the signal from the sensor to the solenoid valve.
4. During normal operation the valve is open.
5. If the flame goes out, the valve stops receiving the signal and goes into the closed position.

After the system is triggered, it takes some time for the stove to turn on , since the thermocouple does not heat up immediately. In different models this happens after 1-5 or 15-20 seconds, sometimes more.

How to choose a stove with gas control

@tehnopanorama.ru
Before buying a stove with a controller, it will be very useful to read reviews about the model you are interested in on the Internet. Owners of household appliances often share information that salespeople in household appliance stores do not provide.

The fact is that now this function is installed on most models, but the speed of operation and its reliability can vary greatly.

Pay special attention to information about how quickly the burners turn on and whether the sensor often fails.

In the store, ask whether the gas supply sensor is built into the oven or only on the stove. Also find out whether repair of the gas safety system is included in the warranty service of the household appliance.

The emergency gas supply stop system makes using a gas stove many times safer and more comfortable. The main thing is to choose equipment from reliable manufacturers with a long warranty period.

How to disable the system

The system ensures safety, but brings some inconveniences , the main of which is an increase in the time it takes to turn on the stove and unstable operation of the burners if the mechanism breaks down.

In this regard, many users refuse the gas control function in a gas stove.
To disable the feature, you must do the following :

1. Close the valve supplying gas to the device.
2. Determine the location of the system (it is different for all models).
3. Disconnect the thermocouples from the solenoid valve.
4. Remove the valve.
5. Unscrew the spring that provides the gas supply/shutoff mechanism.
6. Reinstall the valve and reassemble the entire mechanism.

It is when the spring is removed that the solenoid valve loses its ability to control the gas supply.

Important! The given algorithm should not be considered as a guide to action, as it is unsafe. You should invite a gas service technician who will turn off the system and, after carrying out the work, make appropriate notes in the equipment operation log.

Possible breakdowns and their diagnosis

The system is subject to breakdowns, like any household appliance.
Malfunctions are indicated by :

• switching on for too long;
• unreasonable extinguishing of the flame during cooking;
• continuation of gas supply after the flame extinguishes;
• gas supply to the burner stops.

During diagnostics, the following causes of problems are identified::

• wear of the solenoid valve, thermocouple;
• severe contamination of the thermocouple;
• thermocouple offset;
• weakening of the connection of elements in the system;
• stupor of the gas tap;
• disconnection of the connection chain.

The most common causes of problems are wear and contamination of the thermocouple . In the first case, the faulty system stops the supply of gas to the burners; in the second, the burner ignition time increases.

All elements can be cleaned and replaced, but this is a complex process that requires certain skills. It is better to entrust such work to a specialist.

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.

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.

How does gas control work on gas stoves?

Whether the gas control is mounted on the stove completely or on each element separately, there are no fundamental differences in the mechanism itself. It includes a thermocouple and a solenoid valve.

The first consists of two metal wires of different types, the ends of which on one of their sides are fused together. The melting point looks like a small even ball, when heated, an electromotive force is generated, which is converted into an electrical signal transmitted to the second element. Under this influence, the valve opens, and the pressure created turns the burner valve, releasing gas.

When the fire goes out, the temperature at the thermocouple drops. As a result, the electrical signal first becomes weaker and then disappears completely. The valve remains open while the latter is acting on it. After the electrical signal disappears, the solenoid valve closes, and the gas stops flowing.

If we ignore the technical structure of the principle of operation of the security system and approach the issue from the point of view of its operation in everyday life, actions are carried out in the following sequence:

1. To open the gas, you need to press the corresponding button or turn the knob with pressure. This depends on the type of gas control.
2. Using a match or automatic ignition, light the fire by pressing the gas control and holding it in this state until the thermocouple warms up. After a few minutes, release the button. If you release it earlier, the flame will go out, since the signal of the required strength has not yet reached the valve, which would keep it open.

For reference. In most gas control systems, it is possible to relight the burner without waiting for the thermocouple to warm up if only seconds have passed since the fire went out and it has not yet completely cooled down.

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.

Pros and cons of a stove with gas control

@stroy-podskazka.ru
Gas control of the stove has a number of significant advantages:

• The need to hold the handle down before the fire ignites eliminates the possibility of a small child turning it on.
• Regardless of the reasons for the flame extinction, the system turns off the fuel supply within a minute.
• There is no need to constantly be near the stove; even if something escapes, the burner will turn off automatically.

Owners of stoves with fuel supply control also note the following disadvantages:

• Some stoves with a safety system turn on after 5 seconds, others need to hold the knob for up to 20 seconds until the fire lights up.
• If the thermocouple fails, the burner stops functioning.
• It is impossible to repair a broken sensor yourself; you must call a qualified specialist;
• A stove with a sensor is more expensive.

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.

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

https://www.youtube.com/g0wfotZxikI

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.

Gas control of table burners. Is it necessary or not?

25.01.2018

This question is asked by the buyer when choosing a gas hob or stove. After all, the difference in price between equipment with and without gas control is noticeable. We will not touch on all the technical details of this system, but will try to talk about its advantages and disadvantages.

Advantages.

Safety.

In all built-in gas ovens and in the ovens of GEFEST gas stoves, the presence of a gas control system is mandatory, because gas enters a limited space. And if for some reason the flame extinguishes, the gas will accumulate, and when exposed to a spark, there is a possibility of an explosion. If, when water or milk boils away, the fire on the burner goes out, the system will automatically shut off the gas. Gas control of desktop burners is an additional function; its presence or absence is not regulated by GOST, and the manufacturer installs this system in the equipment at its discretion.

Convenience of turning on the burner (if the ignition is built into the tap handle).

It is not uncommon for gas control of table burners to be combined with electric ignition built into the tap control handle. This option creates convenience when turning on the gas burner. You just need to turn the tap handle counterclockwise and press and hold it a little. In this case, one hand remains free and there is no need to press a separate electric ignition button. In almost all GEFEST stoves, the gas control system is combined with such ignition (in the tap handle).

Flaws.

Price.

The presence of additional, complex elements in the gas control system of table burners leads to a significant increase in the cost of such equipment.

Cost of maintenance and repairs.

The same factor affects the cost of post-warranty repairs at your own expense. If we talk about the gas control system for table burners, then a special tap is installed on each one, with an electromagnetic valve and a separate thermocouple. If the system is combined with an electric ignition built into the handle, then a button control unit is used. Within two years, any breakdown (under warranty) will be repaired free of charge.

It is not convenient to turn on the burner.

And this is not a typo. If the advantages indicated inclusion combined with electric ignition integrated (built-in) into the faucet handle, then the disadvantages included this moment for a reason. The fact is that when you press the faucet handle, it must be held in this position for 3 to 5 seconds. It sounds simple, but in real life it's not fast. One, two, three, four, five... At this time, you do not let go of the handle and do not go about your business, but stand near the stove and wait for the flame to register.

Do not turn on the burner if the gas control is faulty.

This point is perhaps the most significant in favor of equipment without a gas burner control system, since if at least one faulty component of the system is present, it will not be possible to turn on the gas burner even if you use matches, the flame will go out.

Conclusion.

If the gas stove will be used by an elderly person who forgets to turn off the boiling kettle on time, or you have small curious children who strive to turn the control knobs of the gas taps, or you are simply a person who wants to protect yourself in case of a gas leak, then stoves with gas control are yours option and you can’t do without it.

If all of the above does not concern you, then do not waste time thinking and buy a regular stove without gas control of the table burners. After all, our grandmothers and parents lived without him, and we will also live without problems.

Popular models of stoves with gas control and reviews of them

When purchasing a stove, you need to check the presence of gas control not only on the burners, but also in the oven. Different stove models have different equipment. We invite you to familiarize yourself with the rating of the most popular gas stoves with gas control.

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.

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.
