Regardless of the model and manufacturer, the gas hob can stop functioning properly at any time. The flame is of the wrong color or not uniform, the ignition does not want to work as expected, the gas control solenoid valve closes - there are many options for problems. And, if the burner on the gas stove does not work, then, first of all, there is a desire to contact the company with which you have signed a contract for the supply of blue fuel.
However, you must agree that paying a lot of money for calling the master, when it is possible to solve the problem on your own, also does not make much sense. Why involve gas workers, if you can restore the working capacity of gas equipment with your own hands. This is a little out of order, but with the right approach to repair work, it is quite acceptable.

Finding out the causes of the problem
If the burner on the gas stove does not burn well or does not ignite, then first you must disconnect the equipment from gas and electricity. The hob may only be inspected and repaired after shutting off the gas supply.
Basic security measures cannot be neglected here.
Whether or not there is a smell of gas in the kitchen after the burner goes out - it does not matter, any maintenance manipulation gas equipment should be carried out only with open windows and good natural ventilation premises
Many modern gas stoves are equipped with electronics and automatic ignition systems that require power supply. Often, inexperienced home craftsmen, when working with a gas hob, forget about this feature of this appliance. As a result, sparks ignite methane vapors. Therefore, before starting the repair, it is recommended to disconnect from the network not only the stove itself, but in general all electrical appliances in the kitchen.
Problems with gas stove burners arise due to:
- incorrect operation of the solenoid valve and / or thermocouple;
- nozzles clogged with grease and soot;
- malfunctioning spark plugs;
- long break in maintenance of gas equipment.
Owners of private houses and apartments where there is a gas stove are required to conclude regular inspection contract the equipment in question with a specialized organization. Without such an agreement, gas will not be supplied to the consumer.
And gas workers should come at least once a year, checking the efficiency of the hob and, if necessary, immediately repairing it. All other calls are charged separately.
If problems with the stove arose in the period between routine checks, then you will have to either call the master again, or make the repair yourself
Moreover, if during self-repair of the burners and other devices of the hob they are damaged, then it is forbidden to turn on the faulty device without gas workers. Even if the stove is more or less operational, then during an annual check, a specialist of the gas company will detect a breakdown and immediately turn off the gas until the defects are eliminated. And these are inevitable additional expenses. Plus, they can also impose a fine.
It is recommended to take on the repair of a gas stove with your own hands only if you are sure that you will do everything correctly. There are no particular difficulties in these works, but you can break something through negligence or ignorance.
Problems are as follows:
- The flame is not supposed to be blue - there is not enough oxygen or too much gas is supplied to the nozzle.
- The hotplate does not ignite - the spray holes are clogged with soot, or faulty thermocouple or a candle.
- The fire goes out - the gas supply is cut off due to a faulty gas control or problems with the gas pipe.
You can clean or replace the burner on the gas stove yourself. But if the problem area is a meter, directly a pipe with gas (cylinder) or an external gas sensor, then it is better to abandon arbitrariness.
In such a situation, you should seek help from the gas workers responsible for the serviceability of the VKGO and VDGO.
Self-repair instructions
According to the law, only a specialist of the service company with which you must have a corresponding agreement has the right to replace the burners and other elements in the gas stove. However, if there is an urgent need, minor repairs can be performed on your own, and you can say that this was done in order to avoid more serious problems.
If, after such work with their own hands, the stove is working properly, then the gas workers will not be able to make claims.
The first step before starting any inspection and / or repair of the gas hob is to disconnect the equipment from gas and electricity
Before starting work, remove all sources of open fire from the kitchen and prepare a flashlight so that you can look into the farthest corners of the gas appliance. Also from the tools you will need a wrench, screwdriver and pliers.
If the burner does not light up, then first you need to check the presence of gas in the pipe (cylinder). Perhaps the problem lies not in the gas equipment at all. Only after it has been clearly determined that the hob is the problem point, you should start examining and disassembling it.
Situation # 1 - the flame is not blue
If everything is in order, then the gas above the burner should rise from all nozzles with an even blue flame. If the fire contains pink or yellow tints, then the methane (propane-butane) lacks oxygen for normal combustion.
State regulations for kitchens with gas stoves set air exchange at 100 cubic meters / hour - if the inflow or exhaust air is less, then the gas will not burn completely
If the flame is not blue, then the reason for this must be sought in the ventilation. Methane simply does not have enough oxygen required for complete combustion.
To solve this problem, you must:
- provide additional air flow by opening a wider window or transom;
- check the hood for clogging;
- reduce the amount of gas supplied to the burner by slightly closing the valve.
If the air exchange is normal, and the fire is still of the wrong color, then the minimum flame level must be adjusted.
Adjustment of the flame level in the gas burner (1) is carried out using a special adjustment screw (3) on the valve stem (2)
When the screw is turned inside the valve, the plate is displaced, which is responsible for the mixing ratio of gas and oxygen. It is necessary to set it to the desired position, and then light the burner to check the color of the flame.
Situation # 2 - the valve is difficult to open
If the gas control valve on the stove turns with difficulty, then grease has adhered to the stem inside its mechanism, which interferes with the free movement of the handle. It is necessary to remove and clean it from dirt.
The knobs are usually located on the front of the gas stove. You don't even have to lift the top plate to clean, repair or replace them
The pen is cleaned from grease using ordinary soapy water and water. After it is wiped dry and dried, and then smeared with a thin layer of grease and put back.
Situation # 3 - burner nozzles clogged
Grease and / or soot accumulated in the nozzle outlets is the most common reason for stopping gas hob operation.
If the burner on the gas stove stops turning on and does not light up, then the root of the problems must first be looked for in this place.
Each soup that escaped from the pan onto the burner is an additional drop of greasy dirt not only on the upper surface of the stove, but also inside the burner
The design of the hob is such that most of the food leftovers on it remains on top of the hob. Only its upper surface and the grate, on which pots and pans are placed, are stained. However, even a small part of this fat still gets into the holes of the burner and under it into the gas supply channel. As a result, at some point, blue fuel simply ceases to flow for combustion.
To clean the burner nozzle, you must:
- Remove the grate, divider and burner, and then lift the top panel of the stove.
- Clean and rinse the burner in warm water and soap or detergent.
- Clean the gas inlet under the nozzle.
It is recommended to clean the holes in the burner from dirt with wooden toothpicks. If you use metal objects for this, you can widen the holes too much. Then the flame will burn unevenly.
The inner pipe under the burner has a diameter of up to 1 cm. It can be cleaned with a thin metal wire. Toothpicks won't help here. They are too small and fragile. If cleaning the nozzles did not help, you will have to resort to them replacing.
Situation # 4 - incorrect operation of ignition
Each hotplate has a thermocouple flame sensor and a spark plug (if available). Both elements are designed for continuous operation in burning gas at high temperatures. However, over time, even they burn out and fail.
When the flame is extinguished, the thermocouple with the help of an electromagnet shuts off the gas supply to the burner, thereby excluding its accumulation in the kitchen to explosive concentrations
If gas comes out of the burner when the valve is open, it hisses, but does not light up from automatic ignitionthen the problem is the candle. It is necessary to check the wiring for breakdown multimeter, as well as the reliability of its connection to the terminals.
If the insulation is damaged in the wiring, then it is best to replace this cable. Moreover, it should be exclusively in a heat-resistant sheath. Do not cover the damage with electrical tape. The metal body of the gas stove is heated to sufficiently high temperatures. Ordinary insulating tape will melt sooner or later.
The candle itself can only be cleaned of carbon deposits using sandpaper. If there is no scale, and the wire passes the current as it should, then the candle will have to be changed.
If, after ignition, the fire over the burner goes out, then the problem point is the thermocouple, which is responsible for monitoring the presence of a flame in the burner.
To restore the functionality of the thermocouple, it is necessary to clean the tip of the burner with emery paper from carbon deposits. Plus, you need to check the wire connection contacts and the wiring itself. If this does not help, then only replacement will help.
If one burner does not work on the gas stove, then the cause of the problems should be looked for in it. This can be due to both the clogging of the burner holes with fat, and the combustion of a thermocouple or a candle. But if all the burners do not work, then first you need to check the flow of gas into the gas equipment.
Conclusions and useful video on the topic
What to do if the burner on the gas hob does not light:
Why the burner does not ignite or go out on the gas stove:
A failed gas stove is not only an inconvenience with cooking, but also a possible fire due to cotton gas. If a fault is found, the hob must be repaired immediately.
Cleaning and replacing nozzles or thermocouples can be handled on your own, and in case of more serious problems, you will have to call a wizard. And, before calling the gas workers, you should carefully examine the equipment to identify the cause of the breakdown. It is likely that you will not have to pay for the call of a specialist.
