DIY bosch gas stove repair

In detail: do-it-yourself bosch gas stove repair from a real master for the site my.housecope.com.

Cheap printed circuit boards that make up the electronic stuffing of household equipment cost $ 10. The consumer avoids repairing budget gas stoves with electric ignition with their own hands. A price exceeding $ 30 unwittingly provokes the thought of saving money. You visit the forum of radio amateurs: you see ... Ready-made electrical circuits of ignition devices. Wind step-up transformers, look for capacitors, solder, smoke equipment at your own peril and risk.

In contrast to most household appliances, repairing gas stoves with electric ignition forces you to master the technique of replacing resistors. A frequent, ongoing process. Newcomers challenging the appropriateness of the event cause general indignation among members of the forum. They call the dilettante offensive phrases, condescendingly explain, inside the high-voltage unit:

High voltage transformer.
Capacitor.
Diode.
Resistor.

The electrical circuit is specially filled with compound, the burdock will not get inside. You pick it up, saving your hard-earned $ 30. The self-taught ignore the manufacturer's thoughts about protecting products against unauthorized access.

The gas stove electric ignition unit optionally contains control elements - thyristors, triacs. It takes a long time to explain the exact principle of operation of the components of the electric ignition. It is worth noting: the behavior of semiconductor products resembles a key (a tap - plumbers are more accustomed to think). Semiconductor electronic elements are used to drive a power line through a voltage of 5-12 volts.

The analogy of a water valve is complete. A person makes a symbolic effort, opening the tap, releases the incredible power of the pump. The scanty voltage of the control electrode reaches the operating point, the thyristor opens, starting the electric ignition circuit. There are two positions: open, closed. Pure digital microelectronics. Any processor is formed by semiconductor keys - miniature, indistinguishable by the human eye. The PC is considered a logical evolutionary continuation of electronic circuits.

The high-voltage transformer increases the voltage (units of kilovolts) of the output winding, the slot of the burner arresters illuminates the electric arc. Gas is supplied by the handle of the same name, starting the electric ignition circuit. There are other models of devices. Thanks to the spark, the gas ignites:

pressing the button, the cook charges the capacitor with rectified voltage;
the capacity begins to accumulate electrons;
the voltage level of the control thyristor rises when it reaches the threshold value, the capacitor discharges, warming up the primary winding of the transformer;
the output of the electric ignition circuit generates a voltage that causes the arrester to operate;
the spark ignites the gas.

The principle of operation of electric ignition is based on charging a capacitor through a rectifying diode to a certain level. The specific implementations of the schema vary. Be ashamed to study an electrical engineering textbook: repairing the electric ignition of a gas stove with your own hands is easier than a steamed turnip. Know a couple of rules, be able to solder.

The mentioned resistor of the electric ignition circuit is more often with a nominal value of 3.9 kOhm. The dissipation power is 0.5, less often 1 W. The size of the capacity has long been known (according to the opinion of members of the forum) - a couple of fractions above 2 microfarads (the numbers go in jumps according to the rows given by GOST, it will not be possible to find exactly 2 microfarads, except from the E24 series) with an operating voltage of 250 volts. The radio amateur will not notice the difficulties. There were times when TVS were manually rewound!

The average person wants to know the sequence of actions. First, it is necessary to disconnect the electric ignition of the gas stove from the voltage source. The second step is to remove the electronic, high-voltage blocks. The design comes with separate printed circuit boards, a single substrate. There are other options.

Begin inspection by evaluating the quality of the tracks, soldered joints. The conductor layer, which looks like a silver stripe, is covered with a layer of varnish. Made to protect the electric ignition circuit from external factors, primarily moisture. The varnish reliably covers the conductive layer. Do you have nail polish at home? It will do one hundred percent.

Carbon deposits are cleaned with a zero skin, degreased with alcohol, varnished on top. The peeled, torn tracks of the electric ignition circuit are repaired.

Example. The conductive layer is torn. Both edges are slightly cleaned with emery, tinned, connected with solder. A varnish is applied on top of the cooled solder, alcohol is applied as needed. For wiping the PCB, of course.

Burnt resistor is black. The denomination is indicated above. It is not forbidden to put an element more powerful. Eyewitnesses unanimously say: the further process of exploitation is going excellently. Let's give the plate circuit a 9 kΩ resistor. It is better to take the dissipation power equal to greater than the analogous parameter of the original element. 1 watt will do.

The breakdown of the capacitor is visible from afar. Some (electrolytic) ones swell, the swollen keg cannot be missed by an attentive master. Regarding the denominations, it is recommended to ask the members of the forum. Modern marking of resistors with multi-colored rings is more complicated than the existing alphanumeric inscription. Tolerance was expressed as a percentage.

Repairing the electric ignition of a gas stove can be a simple matter. If the transformer windings are burnt out, you will have to buy a new one. Do you want to check the localization of the fault? For each output we find a pair that rings. The resistance (use a multimeter) is hundreds of ohms. There were "legs" hanging in the air: rather, there was a problem with the installation of the transformer. Rewinding a lesson is not easy. The vastness of the network will provide you with valuable information. A core of the form of the letter Ш is used. There are dozen primary turns, the secondary winding will have to be taken seriously.

After examining the circuit boards of the gas stove, pay close attention to the state of the button. Control panel element that initiates the process of ionization of the spark gap. The contacts of the electric ignition button are powered by the voltage of the centralized network of 230 V. Brass contacts with a short circuit of the circuit are easily melted by the welding arc. It is recommended to clean the pads, check the performance of the switch with a multimeter (ringing).

A product that can withstand the operating voltage is suitable. Electric ignition will not work any worse. At times, installation is accompanied by technical difficulties. The button does not fit the installation dimensions of the case. Modify with a file.

The main thing is to solder the jumper correctly, the necessary spare parts are often sold separately.

Each burner is equipped with a candle, a combustion control device (thermocouple). Electric ignition of a gas stove schematically differs little from an ordinary car. Do you want to check if the gas stove spark plug is working properly? Turn off the gas. Remove the reflectors, baffles of each burner (round things that form tongues of fire), look ... When the ignition is pressed, the products give a good spark. 1 candle broken? The reason for the breakdown of the electric ignition of the gas stove was found.

The combustion control circuit is composed of a thermocouple (temperature sensor of an arbitrary type). It happens that the electric ignition works 100%, the gas refuses to burn. The point is rather in this node. The command closes the blue fuel supply path. A properly beating spark of a gas stove is powerless to set fire to air devoid of a combustible mixture.

The electric ignition unit is equipped with 4 or 6 outputs, the literature ignores the reason for the need for the specified number of contacts. We assume 1 pair is used by the oven, grill. Modern trends oblige the manufacturer to produce two-in-one models. A gas stove with an electric ignition of the oven is convenient: you will find models where the opportunity is not realized, and those where you will have to modify the circuit with a copper core. Will need help from her husband.

We will be ashamed to call the electrical circuits for igniting a gas stove complex. Hams make it easier. The getinax board is etched out, the necessary elements are soldered. The original composition of the electric ignition of a gas stove provides a ready-made transformer, the button discussed above.

An experienced engineer can usually improve this by the manufacturer. The Internet gives an interesting scheme for the electric ignition of a gas stove, formed by a triac, striking a simple one.

The electric ignition Zanussi gas stove will make you forget the look of a matchbox. This is what company officials say. The business class segment is represented by products from Gorenje (Slovenia). Despite the abundance of brands, an almost complete list belongs to the Electrolux concern (headquartered in Stockholm). The mentioned Zanussi belongs to the category.

Beholding the experience of Audi, Volkswagen regarding DSG, S-Tronic, one involuntarily wonders how much the electric ignition systems for gas stoves differ in the presented apparent variety. The second thought that creeps into my head is that there will also be a division into premium models and budget brands by brand names.

When buying, check the availability of the oven electric ignition option. The function is not implemented everywhere. Sometimes something may need to be finalized. The average price of gas stoves hovers around $ 400, with Bosch, Ariston and Gorenje out of this range. What attracts the buyer so much.

Among budget models we will meet Hansa, Nord and Zanussi mentioned above. $ 240 and equip your kitchen with a real electric gas stove. Not expensive at all!

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 damagegoing 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:

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 disconnecting gas supply pipes and hoses must be carried out by a gas service employee, after which he draws up an act of repair performed. 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.

Previously, gas stoves were produced without electric ignition. In fact, this is not an obligatory function, but its appearance greatly facilitates the process of using a household appliance: there is no need to buy a special lighter or matches. However, over time, the function often fails. Let's figure out what to do if the electric ignition device does not work on the gas stove and whether it is possible to fix the breakdown on our own.Electric ignition burnerElectric ignition at gas stoves can break unexpectedly: the switch turns, gas comes out, but there is no spark. A breakdown of an additional function can occur for completely different reasons.But first of all, it is worth determining that the function of electric ignition of the gas stove is really out of order. This may be indicated by the following signs:

while pressing the control knob or the button for the burner, the electric ignition function does not work;

automatic functions of the device operate in a continuous mode, sounds similar to clicks are noted. In this case, there is no spark, the gas stove simply does not ignite;

when the handle or button is released, there is no system shutdown;

the device works even without pressing the button;

there is a knocking out of the circuit breaker in the area of the apartment panel when the device is turned on;

the presence of a malfunction can be established according to the piezo ignition and electric ignition circuit, it can be closed.

The electric ignition system is provided in gas-type stoves. Its main purpose is to ignite the fuel that comes from the burner diffuser. The electric ignition device can be of two types:Auto ignition has special piezoelectric elements, which, when the switch is turned on the panel, ignite the gas-air mixture. When using a mechanical device, a special button must be pressed. When pressed, a spark is generated, from which the gas is ignited and ignited.The principle of operation of electric ignition looks like this:

when the user presses the button, voltage is applied to the capacitor region;

after that, the charging of the capacitor begins;

further there is an increase in the level on the thyristor;

as soon as it reaches the permissible limit, the capacitor begins to discharge;

at the output of the device, a voltage appears, due to which the arrester is activated;

the generated spark ignites the gas.

Despite the fact that the process looks complicated, it happens in a matter of seconds. The spark always hits the area of the hotplate that is currently on. In obsolete products, the spark was supplied to all burners, but ignition occurred only on the one on which the gas supply was open.The electric ignition is powered from an electrical network with a voltage of 220 volts. Its work also depends on voltage surges, which can occur quite often. If a power surge occurs, a clicking sound may occur, this usually indicates a breakdown of the electric ignition device.High-voltage unit deviceMany owners of household appliances often have a question, why did the electric ignition stop working? The failure of this function can occur for various reasons, among which it is worth highlighting:

no spark on the electrodes;

moisture or grease has got on the surface of the inside of the system or on the candle;

breakdown of the electric ignition can occur due to the appearance of a crack or due to damage to the insulation of a candle from a ceramic base;

there was a burnout of the transformer - the spark generation unit. Normally no spark is observed when the button is pressed. You can do it yourself, but experts recommend changing the part to a new one;

Spark Generation Unit TestSometimes minor faults can appear as a result of wet cleaning the hob. This usually occurs due to the ingress of moisture into the interior of the household appliance. To eliminate everything, it will be necessary to take preventive measures: clean the contacts, dry the candles. All these actions can be carried out by any user without knowledge and experience in this matter.Malfunction may occur with wet cleaningIt happens that only one burner does not light up. This may be due to a fault in the high-voltage wire that goes to the ignition electrode. Possible breakdown of the ignition device itself, or failure of the block channel.Breakage can sometimes occur when cleaning a hotplateYou can repair the electric ignition device yourself, but you must first carry out a thorough inspection of the device. It is important first of all to establish the cause of the breakdown, the degree of complexity. If the malfunction is simple, then you can fix it yourself.If the electric ignition function does not work well, then the repair process for all models of household products is usually carried out in the same way. All gas stoves have this function arranged in a template.It is advisable, before starting the repair process, to carefully study the device of the stove: you can find information on the Internet or study the attached instructions for use. Knowing how the appliance works will help you perform a high-quality and correct repair.

Repair of electric ignition depends on the type of breakdown. To understand how it is produced, it is worth considering the types of breakdowns and their elimination: the burner should be lit with matches or a special lighter. Look carefully at the type of flame: it should be even, light, and should be spread over the entire circumference of the divider. If a yellow color is noted, then this will indicate an incorrect reading of the gas-to-air ratio. To fix this problem, you need to clean the nozzle or completely replace it. Perhaps the cause of the malfunction is a blockage of the diffuser holes or the presence of moisture in them. It is also advisable to take preventive measures: blow through all the holes, remove the burner body and carefully examine it; To repair an electric ignition, you do not need to have much experience and knowledge, even inexperienced users can cope with this.However, sometimes a thorough check and diagnosis of the instrument is required.It certainly won't work with a flashlight and a simple screwdriver. For this reason, it will be necessary to call a specialist. Of course, the services of a master can be expensive, but sometimes a breakdown in an electric ignition can occur as a result of a serious cause that can pose a threat to a person.Sometimes repairs should be entrusted to professionals.In any case, before starting to repair the electric ignition device, you should carefully study the device circuit. This will help to solve the problem much faster, without damaging the device. It is important to check the combustion beforehand, sometimes it may be the case in the burner or in other components.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 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.

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.

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.

Almost all modern gas stoves are produced with such a useful function as electric ignition. And only the most budget models may not have it. For example, there are such ovens from manufacturers Elekta, Flama, Gorenje and Hansa.The auto-ignition system is often prone to breakdowns. If problem with one burner, then you need to check her ignition electrode. There may be a crack on its ceramic surface, causing the spark to blow to the side.Then the integrity of the wire connecting the piezo and the electric ignition unit is checked. If the entire unit fails, ignition does not work for all burners... Defective elements must be replaced with new ones. The absence of a spark on all burners can also be caused by a malfunction of the power button. If the button is working, then check the power wires. The piezoelectric element in the oven is examined in the same way.It often happens that the oven door does not close. If the oven door does not fit tightly, there is a significant loss of heat, and the cooking process can be delayed indefinitely.. Reasons maybe two:

the mount is loose;

the sealing gasket has become unusable.

The mount must be tightened with a screwdriver. And the gasket needs to be replaced. To do this, remove the door from the hinges and remove the old gasket. Clean the gutter with detergent and install a new seal.May fail gas control devices: due to the constant temperature difference, the thermocouple often burns out. Gas control repair consists in replacing a part. But sometimes users prefer to turn off the protection function. How this is done is shown in the following video using the example of the Brest 1457 slab:

Not recommended leave running equipment unattended... The boiling liquid can overwhelm the flame on the burner, thereby reducing the service life of the gas control mechanism and auto-ignition elements.

Advice! You can use baking soda to remove burnt food from the surface. This will speed up the cleaning process and add disinfection. Cast iron burners and grates are cleaned with a wire brush.

Necessary regularly lubricate the rubbing surfaces at the control valves... How to do this was described above.

It is not difficult to repair a gas stove. But it's even easier to keep it clean and tidy. And then the irreplaceable kitchen appliance will serve for many years, delighting with impeccable work.

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 a gas stove oven 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. Image - DIY bosch gas stove repair

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.
