DIY gas stove repair

You cannot imagine any kitchen without a stove, because the process of preparing a variety of food takes place on it. Mostly everyone knows why gas stoves are more in demand than electric ones. The very first advantage of a gas-powered stove is that food is cooked much faster.

Second - this stove can immediately proceed to its immediate purpose, that is, to cooking or frying. But for an electric stove, it takes some time for the full glowing process to take place. And the third advantage is the rapid cooling of the burners, that is, after turning off the stove, the dish that remains on it will not burn. Do not leave a dish on the electric stove, the hotplate will be hot for a long time.

Gas stoves are much more different from their Soviet-era counterparts. This concerns the technical characteristics and their modern design. Today, the choice of plates is as diverse as their functionality. Therefore, it is important to know which stoves are available for free sale, what structural elements they consist of, and how to repair a gas stove with your own hands.

As always, we start with the most important structural element, which in this case are the burners. The main role here, of course, is played by the nozzles that supply the gas-air mixture to the surface of the burner. The diameter of the nozzle is distinguished depending on the gas used and the level of its pressure. The diameter of the nozzle orifice should be correspondingly smaller at higher gas pressures.

Nowadays, gas stoves have become more versatile, as they are equipped with a set of nozzles. That is, it turns out that, if necessary, you can remove the nozzles installed by the manufacturer and put the necessary ones, this is not difficult to do. You also need to know that if the tile still has a warranty, you can contact the service center for help.

They will change the nozzles for the required ones and at the same time regulate the gas-air process by setting the minimum flame. Provided that the warranty has already ended, you can do the repair of the Darin gas stove yourself, the procedure is not particularly difficult if you read the instructions beforehand.

To the standard number of burners, manufacturers decided to add another high-power burner, which is intended for faster cooking. This additional nozzle has a larger diameter, which creates a more powerful flow of fire.
Also today, manufacturers have begun to make combined burners. This means that there are gas and electric burners on the hob. This option is very suitable for areas where there are frequent interruptions in the supply of electricity and gas.

Gas appliances are usually fitted with hobs made of enamel or stainless steel.If you use plates with enamel coating, then you can choose a product of any color. These hobs are much cheaper.
The stainless steel hob is more practical because it has excellent chemical resistance, does not corrode and is easy to clean.

The modern way of arranging the hob is the use of special tempered glass. This solution for the worktop for gas stoves is borrowed from electric ovens, which have glass-ceramic hobs. If the glass is tempered, then it has increased strength and impact resistance. Such a surface is usually wiped off as it gets dirty with a damp cloth. The color of the tempered glass can be varied.

Gas cookers can be equipped with the following types of ovens: electric, gas or combination grill. Experts believe that uniform heating is carried out only in electric ovens that are equipped with an electric grill. Before you buy some kind of electric oven, you need to check with a specialist whether your apartment will withstand such loads, and find out how to repair the Kaiser gas stoves. Everyone knows that electric ovens are capable of consuming a large amount of energy, and this definitely affects the load on the electrical network.

Gas ovens are classified as follows: designs made without a fan, which has two heating modes, multifunctional designs with forced air circulation.

Usually the first version of ovens is equipped with a lower gas burner and, in addition, sometimes an upper electric or gas grill. In order to achieve the greatest effect of charcoal grilled meat, it is better to use a gas grill. On the other hand, electric grills warm up the dish more evenly. Gas multifunctional stoves have hollow burners so that the fan does not blow out the flame.

Electric ovens are divided into two types: conventional classic and multifunctional. The first model has electric heating elements that are located at the top and bottom. The second model has 4 heating elements: bottom, top, side and rear. These ovens also have a fan to distribute the heated air evenly inside the oven.

The stove, like all other devices, breaks down over time, therefore, a qualified repair of Hefest gas stoves is necessary. But in some cases, you can do the repair yourself, then we will tell you about the most common breakdowns, which, with very great skills, can be eliminated by yourself.

Cleaning the gas stove does not pose any difficulty, and even more so, it does not pose a danger. But you need to take the guidelines and regulations seriously. The very first thing that is recommended to be done before starting maintenance work or repairing an Indesite gas stove is to disconnect the equipment from electricity. If you are working with gas equipment, it is necessary to close the gas valve, because you could accidentally turn on the gas supply.

There are several common problems with gas stoves. One of the most common failures is in the ignition system. To begin with, it is worth shutting off the gas supply in order to deal with this problem. You should also open the doors to ventilate this room. Then bring the match to the burner. If suddenly the stove does not light up for three minutes, you need to turn the screw, which delivers gas in a large direction, until a blue flame appears.

To clean the burner channels, it is better to call a master for this, and you can also do it yourself in the following sequence:

You need to know what a properly configured stove looks like in order to properly repair Ariston gas stoves. The flame, of course, should be bright blue. There should be no intermittent tongues of flame, which indicates a large amount of air. If the color is yellow-orange when burning, it means there is not enough air.

There are several ways to adjust the hob, for example:

Then you need to make certain settings to ensure the normal operation of the hob. Next, repair the brest gas stove and adjust the minimum flame level of each burner and set the desired position of the thermocouple contacts, which are part of the gas control system valve. This is the so-called electromechanical valve, which regulates the process of gas supply to the burner and remains in the open position due to the current generated by the heating of the thermocouple.

If the contacts on the valve and thermocouple are oxidized, it can close and the gas will go out. Gas can be cut off if the minimum flame of the burner is not adjusted. The main concern is security. All modern stoves usually have a fuel leakage protection system. Manufacturers call such a device gas control. It was invented so that, for example, if milk escaped, extinguish the flame by stopping the gas supply.

The scheme of operation of the "gas-control" system is quite simple: when the flame goes out, the sensor cools down and sends a signal to the valve, which in turn closes the gas supply channels. Some modern systems can re-ignite the flame, “thinking” that it was blown out, for example, by a draft. If the attempt fails twice, then the system gives up this business.

It often happens that ignition elements fail. At the beginning of the repair of ardo gas stoves, it is recommended to turn off the stove, remove and inspect the partition. Also, if you see defects in the form of fragments and cracks, then the partition should definitely be replaced. Make sure the ignition control is off before replacing. Test the repaired stove.

How to properly check and replace the piezo ignition tile:

If there is such a problem as a jam or a loose closing of the oven door, and the hansa gas stoves need to be repaired, it is still a little worth unscrewing the door screws and shaking it in different directions so that it fits snugly on the hinges. Tighten the bolts further, then the door should close tightly.

You can correctly replace the door base gasket using this instruction:

Replace the gasket as follows. It is necessary to disconnect the stove from the gas and move it away from the wall. Next, you need to unscrew and remove the gasket. Then you should loosen the bolts on the back panel of the plate and slightly move them away from the body by light shaking. After such repairs and similar actions, the gaskets are disconnected from the installation body, and they must be replaced with new ones.

Gas stove connection

About twenty to thirty years ago, there was no question of how to connect the stove, since Soviet standards allowed only rigid piping using pipe systems, corners and elbows. All this was assembled by the masters of the gas service, who also carried out the repair of the Ariston gas stoves, and the stove was chained forever. It was impossible to move her aside.

At the beginning of the 90s, a stream of imported equipment poured in and brought such a convenient tool as a flexible gas hose. In our time, flexible eyeliner has gained existence because they have fixed all this with regulatory documents. Because of this, modern kitchen design has become individualized.

Today, stoves have many additional functions, so they are connected not only to gas, but also to electricity. With practically the same functions, the price of a gas stove is less than that of an electric one. In addition, gas stoves have a very long service life, which reaches 50 years.

Using special flexible hoses that allow you to change the position of the stove in the kitchen within certain limits, the stove is connected to a gas source. Hoses over 4 meters are not certified, therefore, hoses up to 4 meters are used, which, by the way, cannot be interconnected.

And finally, remember that the transfer to another room of the gas stove and any redevelopment must be coordinated with the relevant authorities. Provided there is good ventilation and a room of the required volume, the installation of a stove is allowed. It is imperative that when self-repairing a gas stove and installing a stove, the tightness of all nodes must be present. With an unprofessional installation, that is, without skills, unpleasant consequences for property and for life can occur.

There is a categorical prohibition, supported by administrative and criminal law, on unauthorized interference with the operation of gas equipment. But not everything that is called gas is directly it. But in reality, repairing a gas stove with your own hands is not only possible, but also necessary. After all, it is not always advisable to pay for the call and work of the master who replaced the faulty pen or adjusted the fuel supply level. And, all the more, there is no need to take an official permit from the gas service for this.

The principle of operation of gas stoves is as follows. Natural gas is supplied to the burner from a centralized gas main or an autonomous cylinder. At the moment of transition from the nozzle of the burner to the diffuser on the burner, the fuel is mixed with oxygen from the air. After that, it becomes possible to ignite the gas-air mixture, the combustion of which will continue until the gas valve is completely closed..

The furnace includes several systems that are responsible for the correct operation of the entire unit:

• gas system, which includes pipes and hoses with taps and burners;
• an electrical component designed for lighting, auto-ignition and grill operation;
• the body of the device, which has a template set of parts and is made of enamelled sheet steel.

Important! The overall design is the same for all ovens. Some models differ only in design and functionality.

The hotplate is the final stage of gas delivery.An already burning jet of a gas-air mixture, moving along the base, fed to the lid, reflected from which it enters the divider... There, the flame divides into uniform little tongues. When the burners are removed for cleaning, the burners with nozzles at the ends are visible. They are also called jets and nozzles. There are three types of burners used.

1. Diffusion... In them, gas mixes with air in a natural way. Used in the oven.
   
2. Kinetic... The pressure in the gas line of the furnace is low. Its energy is just enough to suck in the mixing air and supply it to the burner.
3. Combined... Modern ovens use two methods at the same time.

Panel can be manufacturedbut from enamelled steel sheet. But today most slabs are made from specially hardened impact-resistant glass. Directly under the hob are electrical devices and a gas system, into the pipeline of which several control valves are embedded. The intensity of the flame depends on the degree of opening of the regulators.

The electrical component of the oven includes timer, thermometer and lighting elements. It also includes electronic controls that control the operation of heating elements and fans, which are present in some samples.

Gas ovens are divided into two types.

1. Dual mode, without ventilation. Sometimes a grill is attached to the top of the oven.
2. Multi-mode... The air in the oven is moved forcibly by the fan. And so that it does not extinguish the flame, special hollow burners are used.

To preserve heat in ovens, thermal insulation is used, and the door is made of two or three layers of glass.

Gas leakage is controlled by a thermocouple, which is located in the center of the flame and, when heated, generates a current that feeds a small electromagnet... The task of the latter is to keep the valve on the gas pipeline open. In the event of a sudden cessation of combustion, not associated with turning off the fuel supply manually, the sensor quickly cools down and the magnet turns off. This leads to the interruption of the gas supply.

It takes a few seconds for the hob to turn on for the sensor to reach the desired temperature. AND all this time you need to hold the regulator knob pressed. Some users consider this a serious inconvenience and choose ovens without gas control. Such models can be found from several manufacturers - Mora, Gefest, Ardo, Ariston, Darina and Indesit.

Important! It is better to diagnose a malfunction of a gas oven when it is turned off. Failure to do so may result in a serious accident using a damaged device.

If there is a smell of gas in the room, and the stove is not working at that moment, then somewhere there is a leak of blue fuel. It is necessary to disassemble the oven and smear all connections of the gas pipeline with soapy water both outside and inside. Air bubbles will show where the gas is coming out.

To inspect regulators and shut-off valves, you need to remove the top cover. To do this, remove the grates and burners, unscrew the fixing screws with a screwdriver and lift the hob lid.

To check the inside of the oven for leaks, first you should look at which side of the plate the gas supply goes into it. Depending on what you see, you need to shoot the right or left wall. After detecting a leak, it is required to re-twist the nodes by winding more sealant in the form of a FUM tape or a Loctite 55 thread onto the thread.

Advice! For work involving gas leaks, it is recommended to call the emergency gas service.

Gas stoves, like any other complex mechanisms, are also prone to malfunctions, which are as follows:

• gas stops burning;
• ignition does not occur immediately;
• uneven flame;
• work is accompanied by noise and foreign smell;
• problems with the oven;
• difficulty in turning on and others.

To fix such breakdowns, it is not necessary to call a foreman. Spend self-repair is quite within the power of everyone. But before repairing the device, you must turn off the gas supply to it.... The shut-off valve handle is located on the wall behind the stove or directly on the stove in the area of ​​the back wall.

Troubleshooting should start with cleaning the stove. If small food particles enter the burner, the nozzle is often clogged. Debris is blocking the fuel path. In this case, the flame does not ignite at all or burns unevenly. Sometimes, because of the obstacle, the fire burns only at a minimum. Clean the nozzle you can use a thin needle.

Likewise, food pieces or other debris can fall into the divider. Being in the path of the flame a foreign object can give off an unpleasant odor... Remove the hotplate and clean it thoroughly.

The power or height of the flame is adjusted using the knobs on the hob. Sometimes she can turn with difficulty or stay in place at all. To spend handle repair complete disassembly of the faucet will be required. To do this, you first need to remove the controls and the front panel.

At the faucet, carefully pull out the pin, then remove the spring and plug. All parts must be cleaned of grease and debris. Sharp objects must not be usedso as not to damage the integrity of the plug. After cleaning, coat the surfaces of the parts with graphite grease and reassemble them in reverse order.

Advice! In order to regulate the flame when using canned gas, among other things, it is necessary to change the entire set of jets. For this job, you need a specialist from the gas service. Only he will be able to make the correct setting of the equipment so that the fuel burns out without residue.
