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

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 located below 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:
VIDEO
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, then it means that the ignition or autoignition needs to be correctly 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.
Thanks to such a versatile energy as electricity, the popularity of electric stoves is growing. This site has an article on how to connect an electric stove, and this page describes common problems, methods of identifying and eliminating them.
In many cases, a home craftsman or an ordinary user can make repairs to the electric stove with his own hands, without resorting to expensive specialist services.
Electric cooking
Regardless of the model of the electric stove and the type of burners used, the identification of the cause of the failure of the electric stove should be carried out according to the following algorithm:
Check with a voltmeter for the presence of a supply voltage (it is possible that the circuit breaker on the stove connection line has tripped, the wiring is damaged, or the outlet is faulty;
Make sure that the plug and the power supply cord are in good working order - the glow of the control lamp or electronic indication on the control panel automatically excludes this malfunction;
Disassemble and check the power outlet
Troubleshooting the electric stove
The task of any repairman is localize the problem ... Having gone through this algorithm step by step, you can repair the electric stove with your own hands, having a small set of tools available and having limited knowledge in electrical engineering.
The most important condition on which not only the successful repair of the electric stove depends, but also the safety of the master and those around him, is knowledge of the basics of electrical engineering and electrical safety. You also need confidence in your abilities - some measurements will have to be made with the voltage turned on.
From the tools for disassembling the body of the electric stove, you will need screwdrivers with suitable tips, perhaps a set of keys, pliers. For work inside the case, depending on the detected malfunction, you will need a soldering iron, wire cutters, electrical tape or heat shrink tubing.
Repair tool kit
Sometimes it is possible to identify a problem only by visual inspection (carbon deposits on the contacts, or a soldered wire). But, practice shows that in most cases it is impossible to repair an electric stove without measuring instruments.
Inspect the connections to the terminals
The most acceptable would be to use a multimeter - a multifunctional measuring device, which should be used by any master dealing with electrical engineering. In some cases, you can get by with a voltage probe and a homemade continuity from a light bulb and a battery.
If the mains voltage is normal, and the stove suddenly stops working after switching on, then it is worth checking the outlet itself - perhaps it does not correspond to the power, or the contacts are worn out, and they spontaneously bend during the heating process.
There are cases that in electric stoves with mechanical regulators and burner power switches, the control lamp burned out long ago, and the stove itself stopped working properly much later. At this stage, without starting to disassemble the case, it is possible to identify a malfunction in the switches, including various burners and switching modes their work.
The two burners of the electric stove do not work
If it is found that some of the heaters are working, albeit not at full capacity, then the malfunction of the power cord can be excluded, and you need to look for problems in the switches or in the spirals of the burners.
It is unlikely that all burners will burn out at the same time (although this is possible if all heaters were running during a power surge). Therefore, if there is no reaction to manipulation of the switches, the voltage may not be supplied to the controls.
Since electric stoves and hobs come in a variety of shapes, sizes and designs, there is no way to describe them all in one article, so the user must independently figure out how to disassemble the case. But common to all types of electric stoves is the presence of thermal insulation and it is necessary to work with it very carefully.
Various designs of electric stoves
If the thermal insulation layer of the electric stove is significantly damaged, its energy efficiency will decrease, as well as the readings of the temperature sensors will change, which will entail the stove's malfunctioning in the future.
It must be remembered that it is necessary to work with glass wool thermal insulation only with thick gloves, and the asbestos dust of the thermal insulation gaskets of old electric stoves is harmful to health.
Having disassembled the body of the electric stove, it is necessary to study the internal structure of the equipment, determine the type of regulators, switches and heaters. It will be very handy to have in stock plate layout ... But even without a circuit, knowing the basics of electrical engineering, you can understand the heater control system and identify the problem.
Attention, the following verification methods are contrary to the user's instructions, which prohibit turning on the electric stove when the case is disassembled, so you should be very careful!
If the electric cooker does not work at all, you should check for the presence of voltage at the input of the switches or the electronic control circuit. Imported electric stoves with an electronic control unit are vulnerable to power surges, and very often problems in them are not related to damage to the heating elements.
Electronic control unit for electric stove
If the power cord is OK, and the voltage is on, and the display does not light up, then the internal fuse of the electric stove control unit may have blown. But the indication of a working display does not always guarantee its performance - perhaps there was a breakdown in the power switching relays.
The most accessible way to check the control unit is to check the voltage supply to the terminals of the burner heaters. If the voltage comes in, but the heating element does not heat up, then you need to disconnect the electric stove from the outlet, then disconnect the terminals from the heating elements and ring them.
Checking the supply of voltage to the terminals of the coil of the burner
It will be safer if you first attach special crocodile clips to the terminals of the heating elements, which are put on the measuring probes, and then apply voltage. If only part of the burners is working, then it will be more expedient to ring the heaters first, and only then look for an open circuit in the power circuit. It must be remembered that heating elements can have several coils - the heating power is regulated by the way they are connected together.
If a burnout of the filament or a breakdown on the case is detected, the damaged heating element should replace .
VIDEO If the continuity of the spirals did not reveal any malfunctions in them, then the cause should be sought in the control unit. As already mentioned, heating elements can have several built-in coils, which are switched using switches or electronic relays. In both cases, a large current flows through the contact groups, from which carbon deposits form on them.
Switch for operating modes of the electric stove
Let's say the heating element of an electric stove has two spirals: C1 and C2. For their switching, a three-position switch with three contacts can be used: K1, K2, K3.
Connection diagram of a heating element with two coils
When K3 is turned on, both spirals are connected in series and will work at half their capacity. When K2 is turned on, the C1 spiral will heat up at full strength.The maximum heating will be obtained with the simultaneous closure of K1 and K2 - two spirals will be connected in parallel. All other possible options are meaningless and should be excluded by the switch design itself.
To fix such a switch, you need to disassemble it and get to the contacts to clean them with sandpaper or a thin flat file. You also need to check the tension of the hold-down springs and the fit of the contacts. Cleaning the surfaces, tightening the springs, and bending the contacts will help fix the problem.
VIDEO Connection diagram for a hotplate with three spirals
To ensure the versatility of the heating disc, the built-in coils have different power, and accordingly their resistance is different. More details about checking and connecting such burners are shown in the video:
VIDEO
In the absence of a characteristic click of the relay, ring its coil and check for the presence of a control signal. In the absence of a control signal, a breakdown may be in the output stage or in the microprocessor of the electric stove. To independently repair the electronic control unit, you must have its circuit at hand and have knowledge of radio engineering.
VIDEO For heating elements and disk heaters of electric stoves, it is often used stepless power regulator ... In old domestic slabs, a regulator on bimetallic plates was used, which reacts to the flowing current. In addition, a temperature sensor or thermostat can be installed that reacts to the heat of the heating element.
Electric hob heating thermostat
In such systems, heat generation is controlled by alternately turning on and off the electric stove heater when the temperature is below or above the range set by the regulator. You can get acquainted with the operation and connection of such a regulator by watching the video below:
VIDEO
In case of failure of such a regulator, an identical replacement can be found. But it will be more expedient to install a modern power regulator based on a triac (it works like a dimmer for a lighting system).
Since the triac power control is carried out by changing the shape of the sinusoidal voltage (cutting off part of the half-wave), almost any regulator designed for a given power and current, but taken with a reasonable margin, will do.
Triac power regulator
In some electric stoves, the triac is installed together with a heat sink on the board. If the burner is operating at full power and the heating does not adjust, then the transition in the triac is broken, and it must be replaced.
If there is no current at the output of the electronic regulator, you should check the sawtooth bias voltage at the control electrode of the triac when you turn on the operating mode of the electric stove. This test is carried out with an oscilloscope, which is available in special workshops and some masters with deep knowledge of radio engineering.
Sometimes the electronic control unit is OK, but reacts to incorrect readings of the thermal sensors of the heating control system. You need to find out the type of sensor, study its properties and test methods in order to exclude this option for an electric stove malfunction. It is also possible that the mechanical timer breaks down, the contacts of which are also susceptible to corrosion and oxidation.

Today, the popularity of household appliances powered by electricity is constantly growing, but minor breakdowns sometimes occur during operation. The electric stove is present in every modern kitchen - it is the heart of this space. When a kitchen assistant fails, many home craftsmen are interested in whether it is possible to repair an electric stove with their own hands?
Firstly, a home craftsman who decides to repair an electric stove on his own must at least understand electrical appliances, know the elementary fundamentals of electrical engineering and safety rules when carrying out this type of work. Secondly, you need to be sure that you can perform such a complex repair, and most importantly, find and eliminate the root cause of the breakdown. Third, it is necessary to prepare special tool.
When dismantling electric stoves, you will need screwdrivers for various purposes: for a cross or slot, with different thicknesses, the so-called tip specialists. You will definitely need keys - open-end and capscrews, pliers, wire cutters. For internal work in the body of the product, a soldering iron, side cutters, an insulating tape and, of course, a special device for measuring voltage and resistance are useful.
The photo shows only an approximate set of the necessary tools - during work, the assortment of the tools used tends to significantly expand.
The electric stove looks very impressive - it is a complex household appliance, but its design is quite simple, and all the main working elements are in a special heat-resistant housing which is made of stainless steel.
The principle of operation is similar to all electrical household appliances: the current, passing through heating elements (TEN), heats them to a predetermined temperature. The stove has several burners on the hob, and their number varies: at least two, and the standard is 4. For example, the budget Mechta 15M electric stove has only two burners and a small oven, and the product of Belarusian engineers Hephaestus has a standard set of burners and a voluminous oven.
Burner structure quite varied. Classics are burners on an enameled hob with heating elements inside, modern ones are solid ceramic surfaces with heaters of various types built into them. Let's consider the main types of burners.
Old domestic options are equipped with products cast iron , they slowly heat up and also cool down, creating a steam effect in the kitchen, but they are resistant to moisture and high temperatures.
Tubular spirals - they are made from a hollow tube , when heated, such devices not only give off heat, but also promote the circulation of warm air inside their case, which significantly increases their efficiency. These products are very difficult to repair yourself.
Hotplates ceramic very simple in design, they are easy to repair at home - a nichrome spiral is placed in special cells in a circle and fixed. In modern models, glass-ceramic solid plates are increasingly used - they are more durable and easy to clean.
Halogen devices - these are special burners with a similar emitter, which are installed in different places on the hob. A stove with such burners provides quick heating, in a second, and low energy consumption, so they are the most economical, but only professional craftsmen can repair them.All models of modern stoves to transfer current to the burners use power wire special section, in addition, they are connected to regulators and thermostats, ensuring their protection against overheating.
In different models, the heating level is controlled in different ways: by manually changing the cooking mode or special timers and alarms that control.
During the operation of electric stoves, users may encounter such typical malfunctions.
Sometimes when the product is turned on, burning smell - it is necessary to turn off the stove and inspect the burners, on which the remains of burnt food could remain, which can be easily removed. When there is a smell of burnt plastic or rubber, then you need to call the master.
The heating element does not heat up - here is the fault of the burner or the connecting wires, but first you need to check the controls, maybe the contact has gone away.Impossible adjust the optimal temperature heating the hotplate - it is necessary to repair the switch.
The hotplate does not heat up - if you have a spiral inside, then it often ruptures from overheating or moisture ingress. In this case, it is very easy to repair the electric stove - replace the spiral, that's the whole repair.The oven is not working well - it is necessary to ring the heating elements, in 100% it is their fault, replacement is required, since they are not being repaired.Attention! If the electric stove was connected independently, then not a single service will do repairs for free - you have lost the right to warranty service.
The process of finding equipment failure does not depend on the model of the product and the type of hob or the burners installed on it.
First, using a voltmeter, you need to check the voltage. Do not exclude the possibility of the circuit breaker being triggered, the insulation of the wiring may be broken or the reason lies in the outlet ... If so, then it is necessary to disassemble it, and clarify the reason.
If the indicator lights up on the control panel, and the stove does not work, then there is no power supply to the burners, which means that you need to disassemble the stove.
The correct operation of the mechanical or electronic control unit should be checked - measure the current flow to the burner terminals with the device.
Check the heating element of each burner to find a burned-out coil.
Inspect all thermal sensors, relays and various regulators.
Our task is to find a malfunction and localize the resulting problem. After following all the recommendations, you will find the reason for the failure of the equipment, and we will tell you how to fix it a little later.
Models of slabs are different not only in external shape, but also in size, design - it is impossible to describe a disassembly algorithm that will fit all products. Common factor for all is the presence of a thermal insulation layer - here you need to work with him very carefully. Users should be aware that the asbestos dust of the gaskets under the burners in older models is very harmful to health - keep this fact in mind when disassembling archaic stoves.
initially the hob is dismantled - it is fastened with screws, if you unscrew them, then it can be easily removed. Under it are the burners, supplying wires to them and mechanical temperature regulators, which are located on the front panel.
All this must be dismantled in order to get to the lower part, where the heating elements of the oven are located.
At a modern electric hob with a hob made of glass ceramics disassembling the case for repair will be different - in order to get inside, you just need to remove the top panel.
Important! Repair of glass-ceramic hobs is carried out only by specialists of the service center - amateurs with superficial knowledge and lack of experience are better off not touching such complex equipment.
Below are the common breakdowns of electric cookers.Some of them can be fixed by yourself, others require professional diagnostics and repair.
If you have a stove with burners, then in order to change them, you need to act according to this method.
We unscrew the nut and remove the grounding.
There may be a ring or bracket under it that presses the part to the base.
The burner is fastened with a threaded connection or simply inserted into a special hole. In the first case, we lubricate the thread with oil and carefully try to unscrew it from the case, in the second case, we pry it with a screwdriver and take it out.
If the model is of the old model, then it is better to immediately replace the burned-out burners with modern and economical models that are suitable in size.
If the burners are in good working order, then the reason for the failure lies in control unit - a large current flows through the mechanical regulators, and carbon deposits can form on delicate contacts, which are cleaned with fine sandpaper.
Here's a step-by-step guide on how to repair or replace a switch on an electric cooker.
If there are no clicks when turning the regulator, this indicates that it is defective.
There is an original check of its condition: we put the regulator in the middle position, apply voltage to the stove, the automatic protection should work - turn on and off after 30 seconds.
Before removing the handles, you must study the instructions - on some models they do not understand (Gefest, Kaiser).
First, the control knobs are removed from the outside, then we unscrew the front panel.
A bar is installed under it, which must be removed in order to get to the broken regulator.
If the click is inaudible when the relay is turned on, then it is necessary to check for the presence of a signal - if it is absent, the reason lies in the microprocessor itself or in the cascade at the output. To repair an electronic unit, you need to have a schematic diagram and understand the complexities of radio engineering ... If there is no knowledge and skills, then it is better to turn to specialists - otherwise you will have to buy a new electric stove.
Modern electric stoves on heating elements quite often use a cascade-type burner thermostat.
Sometimes there is a breakdown of such a regulator, for which an identical replacement can be found. Experienced masters advise to install triac type such a device, you just need to take it with a margin of power and current strength. In some models, it is installed on one board along with a heatsink. When the hob burner is operating at maximum, and the heating control cannot be changed, this indicates that it was the regulator that failed for an unknown reason - it urgently needs to be replaced.
Each user should understand that modern household appliances are crammed with electronics, each model has its own, different from others, nuance of manufacturing and control - mechanical or electronic. Outside interference without special knowledge and skills can negatively affect the delicate filling of electric stoves.
If you have a simple stove with burners on an enameled hob, then you can repair it on your own by watching the video:

Why doesn't the oven or gas stove burner with a gas control system ignite? It's all about the pen.
The oven of a gas stove with a gas control system does not work. If the gas control repair did not help, then you can.
What to do when the oven door does not close tightly.
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 divider 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 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 begin 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 used so 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.
