DIY gas burner repair

In detail: DIY repair of gas burners from a real master for the site my.housecope.com.

Does the piezo ignition of a gas burner from a canister not work? Kallong title is drawn.

Today I inserted, holes-holes - and it does not light up. The gas goes on, hisses, the spark jumps, what the hell does she want more?
How are they arranged, are there any chips there? Worked fine yesterday.

The gas percentage may not be sufficient to ignite. Is the liquid in the bottle splashing? Does a match light up?

On the contrary, an excess of gas (little oxygen) leads to this effect.
That is, the spark gap is located in the area of the highest gas concentration.
If it lights up normally from a match, adjust the spark gap.

Sometimes a ring falls out of these golels, if not found, it can be replaced by making it out of copper wire with a cross section of 2.5 mm sq.

In-in, very similar. In this position, as in your picture, when viewed from the end, the spark regularly slips at the top of this tube (from the inside, essno). Where is that ring?

The ring is marked with a red arrow, if it jumps off, the spark will not fly at it, but in different directions and there will be no ignition.
If the photo matches the image of your nozzle at the moment, then the cause should be looked for in the ceramic insulator behind and around the ring.

the reason must be sought in the ceramic insulator,

Although on this burner, when dropped, the ceramic insert generally cracked, but the burner ignites normally without it, but without a copper ring, it does not want to work from the piezo.

Curious. Did not know. Does the material of the ring matter? Steel, aluminum are not suitable? Is copper a kind of catalyst?

My burner is similar to the one you attached the photo, and looks exactly the same. There is one more plastic ring just in front of the plastic body of the balloon landing. It turns back and forth, not a full turn, but like a quarter. Everything seems to be in place.
The spark is clearly visible, one blue lightning flies out from above this ring and hits the upper part of the outer tube of the burner (from the inside, essno). It looks like a beast. no worse than a good car.
But it was like that before. It worked great. What the hell?

Native brass, copper wire was just at hand and bends easily.
Apparently it is possible to replace it with another metal or steel, but this is clearly not aluminum.
Now it stopped falling off. What pleases. It starts to fall off after it cracked (apparently a tight fit and heating does their job), at first I found it a couple of times when I was working in a clean place. Then I sowed it on arable land.

... although it can grow when ringlet

A gas burner with a piezo igniter for a cylinder is a practical tool to use, the presence of which can significantly make your life easier. This tool can be used both in small chores around the house and in the set of a prudent tourist.

The piezo-ignited gas heater is a compact and mobile alternative to the building hair dryer. For operation, it does not need to be connected to wires, a gas cylinder acts as a fuel source, in this a piezo-ignited burner significantly bypasses a building hair dryer, which is less convenient in operation due to the need to connect wires, which are not always convenient to pull.

Gas burner application:

heating and melting of metal or plastic elements;
melting of pipes;
hardening of small metal parts;
quick kindling of a fire, stove;
soldering small parts;
other minor work that requires a mobile heat source.

The gas temperature during combustion reaches 1300–1800 ° C. The tool is easy to use with one hand.

This model of a gas burner is a stove replacement for outdoor enthusiasts. This thing is indispensable for fans of camping. Undoubtedly, you can try to challenge this fact by giving a classic example of making a fire. But in order to cook soup or porridge, it is necessary not only to collect firewood, but also to wait until they burn out a little. For hikes over long distances, this is a significant waste of time; for resting at a halt, you can limit yourself to a short break. Another significant bonus - in bad weather and in the pouring rain, you don't have to dream of a fire, but nothing prevents you from hiding under the crown of a tree and warming yourself up with hot tea or porridge cooked on a gas burner. Piezo ignition eliminates the need to look for matches or a lighter, gas is consumed economically and one cylinder is enough for a long time.

Advice! If you take a gas burner on a hike, watch out for the storage of the cylinder, do not allow direct sunlight to fall on it, overheating in the sun leads to an explosion of the cylinder. When putting it into a backpack, it is better to place the balloon in the middle so that it is reliably protected from high temperatures. Also, the gas is sensitive to low temperatures, the burners work properly at temperatures down to -20. For more severe temperatures, it is necessary to purchase a cylinder of a gas mixture that is not sensitive to cold.

For gas burners, odorless liquefied gas is used, this adds a certain specificity to the use of the tool. Firstly, when using the burner, do not turn it over and tilt it strongly, the flame can go astray and loses its static properties, it becomes uneven. Secondly, you need to be careful when using cylinders. In the event of a malfunction, gas leakage may occur, which cannot be felt due to the lack of smell. You can check the cylinder for leaks with a soapy solution, and you can also dip the cylinder in water for testing.

The device is portable, the mechanism includes the handle of the gas opening valve. In most models, the flame flow control and piezo ignition are placed separately, which makes it easier to use, since by drowning or increasing the flame, you cannot accidentally turn it off completely. The burner body is made of plastic or metal. The time of continuous operation of the temperature flow of the burner on the cylinder is at least 2 hours.

Different models of burners may differ in the power of the gas flow and the ability to regulate it; for some simplified mechanisms, the force of the gas flow is practically unchanged.

Since the gas is liquefied, the flame can go out when the cylinder is tilted. This happens as a result of the ingress of gas in the liquid fraction into the mechanism of the device. But in this regard, it all depends on the device warming up, when it heats up enough (the first few minutes will pass), you can not be afraid of such failures.

The most common flaw in this type of burner can be a malfunction of the piezo ignition. First, you should check if there is sufficient percentage of gas left in the cylinder; for this, light the gas with a match. If everything is in order with the gas flow, then you should look for the source of the malfunction.

Many malfunctions of a gas boiler can be eliminated with your own hands, without resorting to expensive services of the gas service or no less expensive private specialists for the maintenance and adjustment of gas equipment. The only rule that we will immediately make a reservation about is that you need to understand what you are doing and for what purpose.

Seasonal maintenance of a gas boiler consists in cleaning it from contamination and checking its functionality. To access the boiler elements, it is necessary to dismantle the casing or casing. To do this, we decide on the method of its fastening, for different models of boilers this can be done in different ways. Most often these are several self-tapping screws and several latches in the upper part of the casing.

Having gained access to the internal parts of the boiler, we do not remove anything else when performing seasonal maintenance. Using a soft metal brush, a toothbrush and fine-grained sandpaper, we proceed to remove carbon deposits from all parts of the boiler:

heat exchanger;
burners;
igniter, if available.

We use the aforementioned tool wherever it is convenient, without especially leaning on the brush for metal. Next, blow out the collected dust with a compressor. You can use a rubber tube or a medical dropper tube by simply blowing into it and guiding the other end into the boiler.

Important! Any work on the boiler is carried out with the gas valve closed.

Using a thin awl or a strong needle, you need to clean all the holes on the burner and igniter, and then, after cleaning them again, for example, with a toothbrush, blow again. If there are overhead sensors, the places where they fit to the parts of the boiler should be lightly cleaned with emery paper and then wiped with a soft woolen cloth.

The ignition and flame control electrodes are well cleaned only with a woolen cloth, without the use of cleaning agents. If there are immersion temperature sensors, it is necessary to remove them from the sleeves, select the liquid present there from the sleeve, thoroughly clean the sleeve inside using a small metal brush or a loose piece of steel cable of a suitable size. After rough cleaning, the sleeve is cleaned with a cloth wound on a screwdriver, then the sleeve is filled two-thirds with machine oil and the sensor is installed.

After completing these works, the boiler is thoroughly vacuumed. In accessible places, dust and dirt are cleaned with a damp cloth. We put the trim in place. We check the presence of draft in the chimney by attaching a sheet the size of a notebook to the chimney opening, or by throwing a stream of smoke into the ignition ignition hole, the gas valve at the lowering to the boiler must be closed.

We check the seals and possible gas leaks using the soaping method. In the presence of normal draft, a test run of the boiler is carried out, which must be filled with a coolant. In parallel with the work on cleaning the boiler, it is visually inspected for mechanical damage and coolant leaks. At this point, the seasonal service can be considered complete.

It is produced with a solution of hydrochloric acid, purchased in the trade network and designed specifically for this purpose. Cleaning is carried out for the main heat exchangers of wall-mounted gas boilers and heat exchangers for hot water preparation. The channel cross-section of such heat exchangers is small, which is why they are susceptible to contamination with salt deposits.

Cleaning of the water jacket of floor-standing gas boilers, as a rule, is not performed. The heat exchanger must be removed for cleaning. To do this, remove the boiler casing, unscrew the supply pipes to the heat exchanger, after draining the water from the boiler.

We take out the heat exchanger from the boiler.Wear rubber gloves and use a plastic container to collect the used acid. The method is not complicated. Carefully pour the acid solution inside the heat exchanger until it is completely filled. In the event that the heat exchanger is clogged with scale, active foam will be released. Let us leave the heat exchanger for 10-15 minutes.

We drain the spent acid into a container and re-fill the heat exchanger with a new portion. We are waiting for the same ten minutes. We drain the solution and rinse the heat exchanger with running water. We put on a piece of hose on the nearest water tap and spill the heat exchanger with water. Let's fill the heat exchanger with the acid solution again. If there is no active foam generation, and when the heat exchanger is spilled with water, no significant resistance to the flow is visible, then the heat exchanger is flushed, and you can reinstall it in the reverse order.

The method of cleaning the burner from carbon deposits has already been described above. However, with strong soot, it is not always possible to cope with only mechanical cleaning. For such cases, special chemicals are used. It makes no sense to recommend anything, all tools are quite effective. The cleaning method is reduced to applying the agent in the form of a solution to the surface to be cleaned, holding it for a certain time and then removing the exfoliated carbon deposits, usually mechanically. In more detail, you must familiarize yourself with the cleaning method by this or that tool when purchasing it.

In especially difficult cases, for example, when a heat carrier gets on the burner, it must be completely removed from the boiler, immersed in a cleaning solution for several hours. Then remove the burner, ignite in the flame of a portable gas burner. After another application of the solution, using a metal brush or a brush, remove the remaining carbon deposits.

The flue gas duct is checked using a mirror. We introduce the mirror into the channel at a slight angle. In the mirror, we should see a light at the end of the chimney. When performing this operation, it is convenient to use the so-called selfie stick, with a mirror attached to it.

To eliminate the leak, it is necessary to unpack the connection, clean the threads from the old tow and paint. Then, using FUM tape, thread sealing or thread lock, seal the connection again. Check the quality of work by filling the pipeline and the boiler with water.

All accessible areas of gas leaks must be washed with a soap solution or a special gas leak checker. The solution for soaping is prepared from laundry soap by shaving it into a container with warm water and stirring until a thick foam is obtained. If gas leaks, a soap bubble will blow out on the foam. The leak can be repaired in the same way as the water leak through the threaded connections.

Replacing a gas boiler burner will require more attention and care. The purchase of a new burner should be exactly the same model as the one installed on your boiler. Never install a burner not designed for your boiler model.

The beginning is the same - we remove the boiler casing. Having gained access to the burner, we carefully inspect the tubes and sensors connected to the burner. Their location should be remembered so that when assembling a new burner you do not confuse which one to connect to.

How to remove a gas burner. 1. Fixing the burner to the combustion chamber housing. 2. Wires for electrode igniter and flame sensor. 3. A branch pipe for supplying a gas-air mixture

Due to the wide variety of boiler models, it is impossible to give specific recommendations, but in any case, there will be:

a tube for supplying gas to the burner;
gas pressure sensor to the burner;
gas valve.

It is possible that there is a control tube from the draft sensor or electrical connection (wires) from the same draft sensor or temperature sensor. When using a burner of the same model as yours, remembering and connecting all the wires and tubes will not be difficult.

Replacing a horn burner installed in a wood-burning stove is even easier to cope with. We unscrew the screws of its fastening to the plate and two tubes: gas supply and gas supply to the igniter. We take out the old burner, insert a new one, screw on the tubes, tighten the burner mounting bolts.

It is not worth repairing the primitive automation of such a burner, the result may lead to unsafe operation of the boiler. The most difficult thing is to replace the burner of a wall-mounted gas boiler, stuffed with electronics and a large number of sensors. But do not panic here, the principle is the same: it is good to remember the location of all connections to the burner.

Trying to increase their importance, gas specialists say that such a burner should be "tied" to the boiler by flashing the electronic unit or by adjusting the boiler. The burner is just iron, which cannot be adjusted in any way. The settings may require combustion as such, but this is no longer relevant to the replacement of the burner itself. If the burner is made for the model of the boiler on which it is installed, then the combustion will be correct, however, provided that no attempt was made to regulate it on the old burner.

The need to replace the temperature sensor arises when, when setting a specific temperature mode of operation, the boiler either does not comply with it, or, even worse, goes into boiling mode, which can lead to rupture of the water jacket of the boiler or its heat exchanger.

Temperature sensors, according to the method of installation in the boiler, can be overhead and submersible. Clamp-on sensors are installed on the boiler pipes with clips that press the sensor against this pipe. Replacing them is very simple. Disconnect the old one - put the new one. We put the chip (electrical contact) in place of the old one.

Immersion sensors can be of two types: direct immersion and located in a well filled with oil. When replacing the first, it is necessary to drain the water from the boiler, unscrew the sensor. Pay attention to how the threads were sealed at the sensor mount. This can be simply a tapered thread, using a thread lock (adhesive), gaskets, or O-rings. Sealing with flax and other materials is not used. Install a new sensor using the same sealing method.

When replacing the sensors installed in the sleeves, there is no need to drain the water from the boiler. After loosening the fixing nut, pull out the sensor, check for the presence of oil in the sleeve, install a new sensor, fixing it with the nut. The simplest version of such a sensor is an alcohol thermometer installed in the sleeve for visual monitoring of the temperature in the boiler.

Do-it-yourself gas stove repair is prohibited by the legislation of the Russian Federation. True, criminal liability has not yet been provided for, if an accident occurs, troubles are foreseen. In the hero-city of Volgograd, one wise guy brought the combustion products of a water heater into the ventilation hole. 4 people were killed. The authorities classified the case under the heading of causing death by negligence. Gas service technicians have the right to replace equipment and perform service work. Actual, starting with liners, ending with the transition to another type of fuel. Here are a couple of guidelines, not a user guide, just general techniques.

Darina, Hansa, Ardo - so different and the same at the same time. The repair of gas stoves Hephaestus is like two peas in a pod like the repair of Ariston; gas stoves are made up of standard units. It is enough to consider a single device to understand the circuit. Stock up on a handbook to properly withstand gas pressure. When set correctly, the flame is even and blue in color. Orange flashes indicate an imbalance in the fuel mixture. If the settings are incorrect, the flame breaks out (especially in horn ovens).

For those who have read the reviews of the VashTechnik portal concerning gas flowing water heaters, self-repair of gas stoves will seem like child's play! You cannot do it yourself, but you can clean the device. The master will have to clean candles, combustion sensors, burners, and sometimes nozzles. There are many interesting things inside the gas stove. Those who master the correct cleaning of equipment should understand what we see inside. Under the gas stove table:

If the charge is formed by an electronic circuit, you will find a simple thyristor, diode, capacitor, fuses inside. The circuit works, fed by the charge of the capacitor, followed by a surge of energy from the spark gap of the candle. Repair of electric ignition of a gas stove applies to the listed elements. The malfunction is easy to spot. Burnt parts are black or similar.

Gas is endowed with two significant characteristics:

The calorific value is determined by the composition. The higher the methane content, the lower the parameter. The calorific value of natural gas is predetermined by the field of extraction of the natural resource.
The pressure depends on the type of gas. The liquid needs higher. The main line has a typical value of 13 mbar. This parameter ensures the correct operation of solenoid valves, injectors, burners.

If the pressure is too high, the gas does not burn out completely, soot and orange flames will appear. The system may not work correctly. I have come across instructions recommending the use of a reducer in order to obtain a 13 mbar balloon. There are probably limitations. It is not for nothing that it is recommended to put two cylinders in parallel. Please note that the main gas is actually liquid, supplied through a reducer. It is pumped from cisterns into containers from which houses are supplied. Find out the wiring diagram of the house at the place of residence. There is natural gas, distributed centrally, with lower cost, pressure, and heating value. The pressure is assumed to be 13 mbar. It is necessary to consider the aspect when installing and repairing a gas stove.

The reason to call professionals for installation and configuration is that the wizards know the parameters. Of course, the person with the certificate is also aware of the local conditions. Now imagine what happens if you unknowingly connect the equipment incorrectly! This is gas, no jokes. This is especially true for the hinterland, where neighboring houses may have different connections. It is recommended to buy a set of replacement injectors for a different gas pressure. They described the process of self-boring jets, they mentioned: the law prohibits reworking. The work is unsafe. Before buying, ask the gas service for the parameters, ask the store if the equipment is suitable. It’s not too late to do some inquiries during the next cleaning. Not the fact that everything was done correctly.

How to adjust the jets. The size of the center hole changes. Less pressure, the hole is taken more. Verticality and alignment must be maintained, otherwise the gas will be vented to the side, which will lead to an accident. It is pertinent to recall that in old Soviet gas stoves, the jets are hidden in the depths. The design of the burners is unusual. Between the nozzle and the splitter is a tube with a pair of ears attached to the frame. There is one ram for every two burners. In pairs, the pipes are attached with ears inside the case. A bowl with a nozzle is placed at the lower end, a divider is inserted into the upper end. The gas stove is powered by a jet stream. Propane-butane is heavier than air.The peculiarity is that opposite the nozzle there is a tube with a radial cut. Needed to unscrew the hex nozzle without using a long socket wrench. In modern gas stoves, the jet is under the flame. A different arrangement improves traction, discourages ordinary people from climbing inside the stove. Do-it-yourself gas stove repair is a dangerous business.Electric stoves today and for summer residents look more appropriate option.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.

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

The reliability and speed of switching on the protection that blocks the gas after you have finished using the stove depends on how quickly the semiconductors cool down after the flame goes out.

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.

Solenoid valve with induction coil

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:

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.

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 assembliesNow 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 flameIf 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 screwTo 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.
