What is the gas control on the hob

Automatic gas control(gas control).The principle of operation.The main failure.

When a gas leak occurs, that is, when the flame goes out on the burner and the flammable substance continues to flow. this is when the control starts working. It stops the flow of the substance inside the entire stove, oven or cooking surface. It turns out that when there is such a mishap as pouring water on the burner and extinguishing the flame. users can not worry about leaks, because the gas control will take care of your stove automatically.

    , which consists of a wire of two different metals fused at the end into a round ball. When the temperature rises to a predetermined level, a small electrical signal appears at the second end of the part to which this signal is applied, and that should open or close the supply to the desired burners.

  • wire made of special material, insulated. Its main task is to link the valve and thermocouple.

Disadvantages of control system

There is a small disadvantage of this control system in hotplates that comes from the inability of the thermocouple to heat up instantly. Thus, when switching on, it is necessary to hold the knob a little longer than usual so that the valve does not shut off the gas supply. Some stoves have heating speeds of one to five seconds, others can go up to 20 seconds. This inconvenience, of course, can be frustrating, but it is almost the only one in this type of stove. But, unfortunately, this is a must if you put safety first.

The main thing is not to resort to any tricks, because it can damage the gas control system itself and other parts for the stove. Methods such as fixing the handle in the right position can give results, but then you do not know what the consequences will be.

Table Burner Gas Control. Needed or not?

This is the question the buyer asks when choosing a gas cooktop or oven. After all, the difference in price between appliances with and without gas control is tangible. We will not talk about all the technical details of this system, but describe its advantages and disadvantages.

In all built-in gas ovens and ovens of gas stoves GEFEST presence of gas control system is mandatory, because the gas comes in a limited space. And if for some reason the flame goes out, the gas will build up, and when exposed to it with a spark there is a chance of an explosion. If the water or milk boils over and the burner goes out, the system automatically cuts off the gas. Gas control of burners of the work table is an additional function, its presence or absence is not regulated by GOST, and the manufacturer installs this system in the technique at his discretion.

Ease of starting the burner (if the ignition is built into the tap handle).

Not infrequently, gas control of the table burners is combined with electric ignition built into the control knob of the tap. This option creates the convenience of turning on the gas burner. You just have to turn the knob anti-clockwise and press and hold it a little. One hand is kept free and there is no need to press a separate ignition button. Almost all GEFEST stoves have the gas control system combined with such ignition (in the knob).

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

The same factor also affects the cost of post-warranty repairs for your money. If we talk about the gas control system of the table burners, it is installed a special valve for each burner, with an electromagnetic valve, a separate thermocouple. If the system is combined with an electric ignition built into the handle, it uses a button control unit. Within two years, any breakdown (within the warranty case) is fixed for free.

That’s not a typo. If the benefits include the fact that the ignition is combined with the electric ignition integrated into the tap, then the disadvantages include this point for a reason. The fact that when you press the knob, 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 don’t let go of the knob and go about your business, but stand by the stove and wait for the flame to lock.

control

You can’t turn the burner on with a faulty gas control.

This point is probably the most important in favor of technology without the system of gas burner control, as at least one faulty unit system, you can not turn on the gas burner, even if you use a match, the flame will go out.

If the gas stove will be used by an elderly person who forgets to turn off the boiling kettle in time, or you have young curious children who try to turn the knobs of gas taps, or you just want to protect yourself in case of a gas leak, then the stove with gas control is a good solution. This is your option and can not do without it.

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

Failure diagnosis

Like all technical solutions consisting of several components, gas control can fail. It is easy to diagnose. For example:

  • gas is supplied even without the process of ignition and combustion;
  • The burner turns off on its own;
  • The time it takes to start the flame (from pressing and turning the knob to the start of combustion) increases.

Worth noting: some elements of the gas control require strict alignment. That is, a clear placement and configuration. Therefore, it is recommended to involve specialists to repair the gas stove. Especially if the manufacturer’s warranty has not yet expired.

To prevent the gas control from malfunctioning, you must follow the rules for using the oven: keep its surface clean and regularly disassemble and wash the burners. In domestic conditions, with a minimum skill in possession of hand tools, you can clean the thermocouple.

Removing the hob for this purpose. On some stove models, the thermocouples can be removed from the burner to access the thermocouples. After that the element is cleaned. This must be done carefully so as not to deform and displace the thermocouple.

If the user has no experience in disassembly of cooking surfaces, it is recommended to seek help from professionals. An additional motivation for this decision will be a list of simple facts: gas control may not work due to improper installation of the thermocouple, loose connections, jamming of moving parts, wear and tear of electromagnetic coils.

Advantages and disadvantages that characterize such a stove

Gas burner control has a number of significant advantages. Among the main advantages of this function can be attributed to the fact that just because of its presence, it becomes impossible to accidental leakage. In the event of an unexpected extinguishing of the fire, the valve automatically shuts off the blue fuel, ensuring the safety of people in the vicinity.

Despite all of the above advantages, gas control has several significant disadvantages. One of the main disadvantages is waiting for the thermocouple to heat up before lighting the burner. In addition, in the event of a breakdown of one of the elements of the system, the functioning of the burners is impaired. In such a situation, the blue fuel valve will remain closed.

In addition to all the rest, those who are planning to get a stove with a gas control, should understand that if necessary they will not be able to repair the failed system on their own. In such a situation, you should be prepared to wait for quite a long time for service in a specialized service center.

The gas control does not work

Gas control system is a set of elements that control the combustion of gas fed to the gas burner of a stove or cooktop, or any other gas equipment. The operation of gas appliances with a faulty gas control is almost impossible, because it will constantly turn off the burner due to the wear and tear of individual parts. In order to repair the gas control you should contact our service for professional assistance. As a gas appliance organization, we need to have a good understanding of what a stove gas control is and how it works, so we have written this article to demonstrate our knowledge.

Gas control is one of the main safety features in Lex gas appliances. No fire or explosion caused by a power leak because the system cuts the power as soon as the burner goes out.

What is gas control in a gas stove and how to adjust it?

The leakage of gas fuel in a cooking stove is a very dangerous process, which sometimes leads to catastrophic consequences. For this reason, the manufacturers of modern gas appliances use any methods to increase the safety of life and property of their consumers.

One such way is the gas control mode, which almost all modern stoves are equipped with.

What is the gas control system, and how it works

Household appliance manufacturers strive to improve the safety of appliances used in the home. Therefore, they develop special devices that prevent the occurrence of fire in the event of a gas leak. Gas control is a reliable system, the elements of which control the flow of fuel to the burners of the hob.

If the fire on the hob has gone out, but the gas continues to come out of the pipe, there is a leak. When for some reason this happens, the control mechanism cuts off the gas supply to the inside of the cooking surface. Leakage can occur due to accidental ingestion of liquid inside the burner (e.g. escaped milk). The fire can also be extinguished by a strong gust of wind.

Modern models of gas appliances are equipped with a gas control system that makes you feel completely safe. Even the least expensive versions of gas ovens have this.

This mechanism works quite simply. Each burner on the stove is equipped with a burner and a flame sensor. The main active components of the sensor are: a device called a thermocouple, a solenoid valve, wires.

Thermocouple consists of two wires fused together in a special way. They consist of different types of metals. At the junction of the wires is a round element that senses temperature changes. It is placed where the burner flame appears.

control

The electromagnetic valve is directly connected to the burner gas supply valve. And it’s connected to the thermocouple by a wire. All the wires are inside the insulating material.

When the stove is turned on, there is a fire in the burner and then the ball of the thermocouple is heated. This process takes a few seconds. When this element is heated there is an electrical signal at the other end of the wire. This signal is fed to the solenoid valve, which opens and presses the burner tap.

If the flame in the burner is stable, there is a steady electrical signal to the valve. Thanks to this the tap stays open and the gas supply is stable. If the fire on the hob or in the oven goes out suddenly, the heating element cools down and no electrical signal is emitted.

When the pulse stops, the valve closes the valve and the gas supply is cut off. This is how you ensure the safe operation of the gas burner.
