In detail: do-it-yourself repair of the Hefest gas stove oven from a real master for the site my.housecope.com.
Draw your attention to!
Without performing the manipulations specified in this article, it is impossible to replace the hinge (hinges) of the oven door, because without removing the inner glass of the oven, it is physically impossible to get to the hinge, because it is located inside the door frame, inside, between the glasses. Therefore, if the inner glass has not yet been removed, go here.
Breakage of the door hinge, after which the oven door is usually skewed and the complete impossibility of frying an appetizing, crispy goose crust, is a common thing.
Let's start first with the design of the hinge itself and with that little secret that you need to know .
In a hurry, you can rush to the door and try to remove it right away. Don't try - only a crowbar will help. The point is this. The hinge consists of two halves.
One half is bolted tightly to the frame of your gas stove.
Moreover, when replacing the hinge, it remains intact. The other half, equipped with a spring, is wound up with its own “hook” and, after docking, is fixed with a lock. You will not notice this lock at once. No need to break down the door. Just lift the flags on both hinges - then the oven door can be easily removed. In the photo, a red arrow points to the hinge lock. It's one thing, of course, when the hinge lies quietly on the table. Another is when we look at the stove. Therefore, we give a photo where the hinge lock is shown directly on the oven door, so to speak, in working order.
After removing the door, it remains only to unscrew the two screws. They are marked in the photo. The oven door hinges (hinges) are presented as a complete set ready for installation. This kit itself consists of two hinges. Moreover, they are interchangeable. That is, there is no concept of placing them on the door: this one should be on the left, and the other on the right. It is impossible to make a mistake when replacing the hinge. The mating part is not supplied in the kit, as it is unnecessary. Because nothing ever happens to her.

Sooner or later, the need to repair the gas stove overtakes almost all owners of these devices.
It is often costly to contact a master, and you want to troubleshoot at home so as not to waste time transporting tiles and repairing them.
There are a number of problems with gas stoves, such as the regulation of the electric ignition, which you can really deal with on your own.
An analysis of the most common breakdowns in plates and ways to solve them, as well as a video that reflects all stages of work, will help you with this.
Before doing repairs, you need to understand what a gas stove is, what details are present in it, and what kind of repair of a gas stove with your own hands may be required in one case or another.
There are many companies producing gas stoves: Gorenje, Ardo, Ariston, etc. But all tiles, even if they differ in price, have a similar type of interior arrangement.
The most visible part of any stove is the burners. Each hob is bolted to the stove table. The burner also consists of several parts: they have a lid, a divider and an injector.
A steel and copper tube is connected to each burner, which has a fastening similar to the American one. Due to this device, the burner receives gas.
Gas burner device
No special tools are required to work with the burners: you will need a key, most likely 13, to disassemble the parts of the burner if it needs repair or cleaning.
After completing the repair and assembly, you need to assemble the structure and check how tight it is in order to prevent gas leaks.
Each burner has two candles around the perimeter.
One helps to create ignition, working with piezoelectric elements or an electronic circuit, and the second serves as a thermocouple connected to the circuit that controls the combustion.
Gas burner (grid for dishes removed): 1 - nozzle, 2 - electric ignition plug, 3 - flame sensor (hot junction of thermocouple)
Candles differ from each other even externally, so it will be difficult to confuse them.
A candle for electric ignition has a ceramic caftan, it is needed to prevent sparks from breaking below the required level.
That is why it is important to properly ground the stoves where the electric ignition is built in. Also, electric ignition does not tolerate the use of liners for water supply and metal threads.
It is important to separate the slab from the riser with special gaskets during installation and repairs, otherwise there is a real risk of explosion.
The thermocouple candle has a bronze caftan, which is a powerful conductor of heat
How quickly the semiconductors cool down after the flame goes out, depends on the reliability and speed of switching on the protection that blocks the gas after you have finished using the stove.
A manifold can be seen under the slab table. It looks like a thick tube, from which the liners to the burners diverge.
The gas flow is controlled by solenoid valves, the number of which is equal to the number of burners on the stove.
This is necessary so that if the flame of one burner goes out, the others can still function.
The solenoid valves are equipped with an inductor. When the thermocouple is heated, an EMF is formed, which fixes the device open.

A full repair of Hephaestus, Gorenje and other models of gas stoves requires the intervention of specialists, because it will be not only difficult to do it on your own, but also dangerous.
However, there are a number of works that can be done with your own hands at home, and bring the stove into working condition if its damage is not too serious.
The most common problem with gas stoves is the failure of the electric ignition. A video will help you fix this problem - watch it before starting the repair in order to do everything right.
Video instructions for repairing an electric ignition using the example of a Gorenje stove:
VIDEO First of all, you need to disconnect the stove from the power supply, remove the partition from it and inspect for deformations.
If you see that there are chips and cracks on it, it means that this is why the stove does not work, and the partition should be replaced.
It can be changed only when ignition or autoignition is disabled - do not forget about it. After replacing, check how well it works now.
If a piezo ignition is built into your Gorenje stove or another model, then the operating technology will be slightly different.
Replacing the spark plug
First you need to remove the device from the control, then remove the plate partition from the bottom and remove the igniter, which is screwed to the bracket with the fastener.
If it is cracked or otherwise deformed, it should be replaced with a new one. To install a new igniter, you need to turn off the module responsible for ignition.
The instructions for the stove will help you find it.
After that, in place of the old part, you need to install a new igniter and check how well the gas stove is now working.
Often, after prolonged use, the oven doors begin to stick or do not close properly.
To make a similar repair of Indesit, Gorenje and others gas stoves, you need to unscrew the screws that hold the doors and swing them in different directions so that the door is firmly fixed on the hinges, from which it may have fallen off.
After that, re-tighten the bolts, if everything is done correctly, then the door should snap into place, and the oven should close tightly.
Video instructions for repairing the oven door:

If the part still does not work, then perhaps you should replace the gasket, which is responsible for the tight fit of the oven door to the stove frame.
To do this, you need to unscrew the door hinges, which are located above the handles, and remove the plate cover.
Most likely, you will also need to remove the internal screws and panel edges, or you can simply move them aside and thus remove the cover.
The screws with which the glass is fixed on the panel block must be removed, and then the glass itself must be removed by disconnecting the gaskets that hold it.
Oven door hinge assemblies
Now you need to detach the gaskets themselves, which are between the door and the glass from the inside.
Now you need to change the gasket to a new one and put all the parts back in place, proceeding in the reverse order.
Use the manufacturer's instructions, as the device of different models will be slightly different, and you will have to act in different ways.
It often happens that the gas supply to the burner is not adjusted correctly. As a result, the flame burns intermittently or disappears altogether. If the device is working properly, the flame should be even and have a bright blue color.
Correctly adjusted minimum flame
If your device works in a different way, it means that the ignition or autoignition needs to be properly set up and adjusted the stove.
To do this, you must first turn off the gas supply and then remove the baffle. Then you need to turn it back on and determine which air damper needs adjustment.
Flame adjusting elements: 1 - gas burner, 2 - valve stem, 3 - minimum flame adjustment screw
To adjust the work, you need to unscrew the set screw that locks the plate - it is responsible for the proportion in which the gas mixes with air.
Having set it in the desired position, turn on the stove and check how it works.
It is impossible to imagine any kitchen without a hob, be it an electric or a gas stove, since it is on these units that the cooking process takes place. But unfortunately, these devices fail over time for various reasons. Repair gas stoves, fix all kinds of breakdowns and carry out maintenance qualified gas service specialist ... But there are minor faults in which you can fix the gas stove on your own. So, you can repair a gas stove with your own hands with the following malfunctions:
one or all burners do not light up;
electric ignition does not ignite the gas;
after the gas is ignited, the burner goes out;
the oven lid is not covered.
This malfunction can be caused by a number of reasons:
clogging of the gas supply nozzle;
failure of the ignition plug;
damage to the insulation of the wire going to the candle;
faulty electric ignition control unit;
malfunction of the power button.
The nozzle (jet) of the unit can become clogged from food, detergent powder or gas combustion products. In this case, self-repair of a gas stove is very simple: you need to remove the burners and clean the nozzle a wooden toothpick (do not use metal objects such as a paper clip or needle for cleaning).
If you cannot clean the nozzle without disassembling the stove, then you should remove the top panel of your device by unscrewing a few bolts. For a good cleaning of the jet, it can be unscrewed.
Before disassembling the gas stove, you should disconnect from it the power supply (voltage for the candle - 220V), which is required for electric ignition. This malfunction of the electric ignition device can affect both one burner and all at once. If the spark does not skip on one burner, this means that the ignition plug (electrode) is out of order. On it, in the ceramic insulator, a crack may form, as a result of which the electrode stops working correctly.
To repair a gas stove with your own hands about replacing a candle, it is enough to remove the burners, open the stove cover (by unscrewing a few bolts), and change electrode on new.
Also, a frequent malfunction of the electric ignition on one burner can be wire damage going to the candle. To check this, press the ignition button with the unit cover open. If the wire is “punctured” in any place, then you will see a spark slipping in this place either on the body of the device or on the foil that covers the oven. Repair of electric ignition of a gas stove with a damaged wire consists in replacing it with a new one, or it must be moved to another place so that there is no “breakdown” to ground.
In the case when the electric ignition does not work on all burners, including in the oven, this means that the ignition unit is out of order. To repair the autoignition, you need to replace the unit with a new one after removing the top panel of the device.
The process of repairing the electric ignition of Darin's gas stove is shown in detail in this video:

There are times when a properly working gas stove suddenly starts to present surprises. For example, you turn on the gas supply, it lights up, and after releasing the handle, it immediately goes out. Such symptoms speak of thermocouple faults - a sensor that turns on the supply of a combustible mixture.
A thermocouple works in the following way: when heated, it generates an electric current, which magnetizes the solenoid valve. The valve, in turn, opens and the gas flows freely into the burner. If the thermocouple stops heating, the electrical impulse is lost and the valve shuts off the flow. Thus, if, after opening the tap to turn on the gas and ignite it with an electric candle, combustion stops immediately, this means that the solenoid valve has triggered and cut off the supply of the combustible mixture.
It is quite simple to repair a gas stove with such a malfunction.
First, you need to remove all the handles and the top panel of the stove by unscrewing the bolts on the sides of the lid and under the burners (stove designs may be different, respectively, and the location of the fasteners may differ).
After unscrewing the fasteners, remove the top cover of the unit.
After disassembling the unit, you will see two protruding parts near the inoperative burner. White is the ignition plug, and next to it is the thermocouple.
A wire goes from the thermocouple to the connector, from which it should be pulled out. Disconnect the gas control sensor from the burner.
After removing the non-working element, install the new one purchased in advance.
Thus, it is possible to repair the Hephaestus, Ardo gas stove, Brest and Hansa stoves if the thermocouple fails.
Also, do not forget about safety precautions: before you repair the gas stove, you should disconnect it from the mains.
Sometimes a broken button can be the cause of a spark plug failure. This malfunction during the repair of Gorene gas stoves or other brands can be determined by throwing the wires (after removing the top panel of the device) to another button gas stoves. If the ignition works when the burner tap is opened, then the faulty button must be replaced.
The most common oven breakdown is poorly closing the oven door. It occurs most often when there is a small child in the house who simply sits on the open door, as a result of which the brackets holding this part bend and do not fulfill their function of pressing the sash.
To repair the oven of the Indesit gas stove, Brest 1457 or the Flama stove, you will need disconnect the door from the unit ... To do this, you need:
Since the door is held on hinges equipped with latches, they must be bent on both sides of the unit.
After that, you must carefully close the door until it stops in the latches.
Next, you need to pull the door slightly towards you and up, after which it will easily detach from the stove.
To get to the brackets when repairing the Gorenje gas stove or when repairing Darin's gas stove, as well as the Brest unit, it is necessary to remove the side walls of the oven. Removing the sidewalls, you will see brackets , which are responsible for the clamp.
The brackets must be removed from the oven of the gas stove and visually determine where they are deformed. Using a hammer and pliers, you can try to straighten out the deformed places. But in the event that this part is broken, it must be replaced with a new one. The stores sell different types of spare parts for repairing the oven and stove. Select the brackets that match your gas stove model.
Summing up, we can say that only the above malfunctions can be eliminated with your own hands. All types of troubleshooting of gas stove malfunctions associated with the disconnection of gas supply pipes and hoses must be carried out by a gas service employee, after which he draws up an act of performed repairs. The same rule applies to connecting the gas stove to the mains - it must be carried out by a specialist. To carry out self-repair, it will not be superfluous to get acquainted with how the gas stove is arranged.

Gas stove device: 7 requirements for operation
Everyone knows that combustible gas mixed with air is explosive, which is why, for the sake of safety, a special substance with a pungent odor is added in small quantities. In the event of a gas leak, it is imperative to call the Gas Control Service.
In order to completely protect yourself and your home from a gas explosion during repair work, it is imperative to comply with certain requirements, namely :
Completely de-energize the apartment, turn off the main machine or unscrew the plugs;
Take out mobile devices with autonomous power supply and de-energize uninterruptible power supplies;
Open wide doors and windows throughout the room;
Use only special tools and accessories;
Close the shut-off valve;
Eliminate existing faults;
After work, apply gas by opening the valve.
If, after carrying out repair work and supplying gas, an incomprehensible hissing or gas smell appears, close the valve again and contact a gas service specialist. You can easily and quickly repair the gas stove and eliminate the existing faults on your own, the most important thing is to follow the instructions carefully and follow the safety rules. If you need to repair the gas stove yourself, then initially you need to decide on how exactly the device is arranged and which components and parts allow it to work normally.
A modern gas stove consists of such systems as :
The base part consists of the burners, burners, shut-off valves and pipes.The electrical part is responsible for good lighting, electric ignition, and sometimes, in some models, also for the grill system if it is installed in the oven. The supporting structure is mainly the body of the product, made of stainless steel.
Each gas stove has a standard set of parts. Depending on the model of the device, it can have a different configuration and certain nuances, however, their equipment is unchanged.
One of the main parts of the gas stove is the burner, located inside the stove under the hob itself, and on top of the burner there are burners with dividers, which can be removed and washed during wet cleaning, however, the most important thing is that no water gets into the dividers. Each burner is characterized by a specific specific power and is determined by such indicators as: minimum flame when the handle is in the extreme left position; medium fire - the flame regulator is in the middle; maximum combustion when the regulator is in the right position. When choosing a product, you need to pay attention to such an indicator as the maximum combustion power. It is determined by the level of gas combustion and is indicated in the technical characteristics of the gas stove itself.
In all gas stoves, without exception, burners of three types are used, namely :
Kinetic;
Diffusion;
Mixed version.
Diffusion burners are characterized by the fact that the gas stream enters the burner, where it mixes with air. When the oven burner is lit, air is drawn from the inside of the hob. The principle of operation of a kinetic burner implies that the gas is mixed with air during movement and then the combustible mixture passes to the burner. In modern models, a mixed version is used, that is, part of the air is taken from the inside of the device, and the rest comes from outside.
Repairing a gas stove requires certain skills and it is very important to know how to properly disassemble the device in order to perform the required work. Before disassembling the product, turn off the gas valve. If you follow all the steps according to the instructions, then you can disassemble the stove and troubleshoot yourself. Then you need to disconnect the stove from the gas network and electricity.
Dismantling the slab consists of several stages, namely :
Remove the burners, unscrew the bolts, lift the top cover;
To access the oven slide, it is necessary to remove the side wall;
Remove the burner nozzle.
If there are problems with the operation of the stove and the burners do not ignite well, then a mandatory ignition adjustment is required. If only the burner is faintly lit, then the problem may be a blockage. The repair is very simple, as it is enough to clean the nozzle using a thin wire or needle. Getting to the oven nozzle is not always easy, for this you need to unscrew the bottom wall of the oven, remove the burner and clean the nozzle.
Important! The structure of almost every gas stove is the same, therefore, it is enough to study the features and technical parameters of one model and it will be possible to carry out repair work without much difficulty.
Gas can periodically disappear if the thermocouple is damaged, therefore, if there are problems with the fuel supply, you need to inspect the integrity of the part. If the flame ignites for a very long time, then the solenoid or gas valve of the burner fuel flow rate must be replaced or repaired. In addition, it is necessary to correct the operation of the thermostat. There may be other malfunctions of the stove, therefore, if there is no experience with gas equipment, it is best to give it to a professional master, let him repair the device.
Very often it is necessary to turn off the slab to replace the flooring or carry out repairs.When you turn off the electric stove, there are absolutely no problems at all, you just need to unplug the cord from the socket. When turning off the gas stove, it is important to observe safety precautions and it is advisable to contact the gas service technician.
Regardless of the model of the gas stove, turning it off consists of such actions as :
Blocking gas access;
Removing the locknut;
Removing the coupling on the lowering to the plate;
Installing the plug.
Regardless of how long it is necessary to turn off the gas stove, it is imperative to control the flow of gas into the burner, since an explosion can occur when mixing fuel with air. If the stove needs to be turned off for a long time, then a plug must be installed on the pipe leading to the gas main.
Regardless of whether the old gas ovens, in particular, such as Darina, Wrozamet, Brest 1457, Elekta or new, modern models, the principle of their design and operation is identical. Models in which the hob surface is separate from the oven are considered very convenient and functional. In particular, such Hephaestus, Ariston, Indesite, Ardo, Kaiser, Hansa can be distinguished. Multifunctional devices that are easy to maintain and repair are considered to be such as Hansa, Gorenje, Bosch, Zanussi.
Some gas ovens may not close the oven door tightly enough or have other problems. If the electric ignition function does not work well, it means that the device is clogged and requires urgent cleaning.
When carrying out repairs to ovens, it is imperative that :
Inspect the integrity of all its parts;
Check the tightness of the connection to the gas hose;
Inspect the door for damage.
If the door breaks or it does not close well, then you need to either carry out repairs and tighten all existing fasteners more tightly. In the event of a serious breakdown, if the oven cannot be repaired, it will be replaced. In addition, when carrying out repair work, you need to inspect the handles of the gas stove, as they can often break and for this reason the device does not turn on well.

You can repair the gas stove yourself. The most important thing is to study the principle of operation of the device, its main parts, and also strictly observe safety precautions.
Almost every owner of a gas stove at least once in his life has encountered its breakdown. It is often quite costly to seek help from a master, so home craftsmen try to fix the problems on their own so as not to transport the stove once again. There are models of gas stoves that can be repaired by hand, especially if the problems are related to flame adjustment, replacement of electric ignition and other minor breakdowns. In this article, we will tell you how to repair the oven, gas stove and hob with your own hands, we will give a number of the most common breakdowns and ways to eliminate them.
Many gas stoves from different manufacturers have the same design. It is enough to consider, using one example, how the repair takes place in order to understand the technique of performing the work. To withstand the pressure of natural gas, you will have to stock up on useful information.
Important! If the setting is correct, the flame glows steady blue. If orange flashes occur, this indicates an imbalance in the fuel mixture.
After reading the information below, you can repair the Hephaestus gas stove or any other brand with your own hands. Having decided to master the correct cleaning of such equipment, you need to figure out what is inside.
Important! The oven is an integral part of the gas hob and requires the same care and attention as the hob.In a separate article, we have collected the best tips - click on the link and read about effective ways to clean the oven.
The following elements are located under the slab top:
Hotplates. As a rule, they are bolted to the stove, and each burner consists of a divider, a cover, an injector. A copper or steel tube is suitable for each of them. To remove the hotplate, you need a 13 key.
Important! The main thing is not to rip off the head or thread during cleaning. It is better to check the tightness of the assembly with a soapy solution. It is necessary to apply foam to the nodes, test the part.
Candles. They are located around the perimeter of each burner: one is used for ignition, the other is a thermocouple, that is, an included combustion control circuit. It is quite easy to distinguish them from each other. The high-voltage spark plug is covered with a ceramic caftan.
Collector. This is a thick tube from which the wiring runs directly to each burner. The gas supply is controlled by a solenoid valve. Their number corresponds to the number of cooking zones. If the flame of one of them is extinguished, then the rest will still burn.
Distribution reinforcement plate. Single high-voltage wires run to each ignition electrode.
Important! If the hob is not grounded, there is a risk of electric shock.
Thyristor, capacitor, diode, fuses. These parts are present inside the cooker if the charge is generated by means of an electronic circuit. It is powered by a capacitor charge and starts to work from a surge of energy from a candle.
Important! If one of the parts listed in the last paragraph burns out, then it is easy to replace them yourself.
Let's figure out how to fix a gas stove, if, for example, the burner began to burn weakly. By the way, this is the most common problem with such devices: gradually the flame begins to partially disappear due to clogging of the diffusers or burner nozzles.
Important! If you cook inaccurately on the stove, the small holes will be clogged with the remnants of boiled milk or soup, crumbs. This happens even if an excessive amount of detergent is used. Therefore, try not to bring the burners to the point where the blue fuel stops flowing into the burner.
If the problem still arises, then it is necessary to remove the burner, thoroughly clean the divider or nozzle with a knitting needle or needle.
Important! Some models of gas stoves have plastic valve handles, put on the stem by means of a metal plate that is inserted into the groove. The handles begin to loosen with use, the plate flies out and is simply lost. Don't be upset, you can fix the problem. Take the most ordinary metal lid for canning or from a tin can, carefully cut out a suitable plate with scissors and insert it into a special groove on the handle.
If over time the handles of the valves began to turn tightly or sink, then they should be lubricated and the drains should be cleaned from oil, grease, and dirt. Enough:
Remove the handles, the front panel of the plate, which is more often fastened with latches or bolts.
Then carefully disassemble the taps, unscrew the pins holding the stem.
Then remove the spring, plug, use rags to clean them from dirt.
Important! The plug should be cleaned as carefully as possible so as not to scratch it, as this can cause gas leakage.
Next, you need to lubricate the plugs with graphite grease, but it is important not to close up the holes here.
Then you need to take the stem, clean off the dirt and grease from it with a knife, insert the plug back, insert the springs into it, and secure the stem with a hairpin.
Many housewives are faced with such a problem as a jam or a loose fit of the oven door. Repairing a gas stove in this case is very simple:
It is necessary to unscrew the screws that secure the door to the plate, but not completely.
Swing it slightly so that it returns to its place and sits firmly on the hinges.
Then it is necessary to tighten the bolts in place and check the tightness of the door. This is done simply: insert a sheet of paper between the seal and the top edge of the plate, make sure that it is firmly pressed by the seal.
Important! Working with modern technology can lead even the most advanced person to a dead end. We bring to your attention articles with the most common questions from oven users. Their name speaks for itself:
Not less often, the owners of gas stoves face a problem when the gas control system fails: when the burner is ignited, you press the button, and the flame burns, as soon as you release it, it immediately goes out. Don't panic right away.
The first step is to clean the thermocouple, in other words, it is the iron part that is next to the burner. When it heats up, a current is generated that holds the solenoid valve in its working position and does not allow it to interfere with the flow of gas to the burner. If for some reason the gas goes out, the thermocouple cools down and the valve closes immediately, preventing the gas from entering the room. In order for the system to start working in the previous mode, it is necessary to clean this part with sandpaper.
Important! If this procedure was not enough, then you will have to change the thermocouple.

Is there a Burning gas stove in your kitchen? You can easily perform DIY repair of this device if you listen to the advice of professionals. But if suddenly you smell gas, then immediately turn off the fuel supply valve and call the master. Do not forget to regularly clean and wash the stove, take care of it, because it will answer you with high-quality and durable work.
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.
Diffusion ... In them, gas mixes with air in a natural way. Used in the oven. 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.Combined ... Modern ovens use two methods at the same time.Panel can be manufactured but 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.
Dual mode , without ventilation. Sometimes a grill is attached to the top of the oven.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.
