DIY gas stove repair and shutdown

The gas stove has long been a reliable assistant to the hostess. Most homemade recipes for hot dishes and pastries are designed for this unpretentious and reliable unit. The cost of a unit of heat is also lower than in the case of using an electric stove. If minor damage occurs, the home master may repair the gas stove components with your own hands.

Disabling the gas stove during repair

Household gas and gas appliances are a source of increased danger. Improper handling can lead to fire or even explosion. Gas equipment is installed in places strictly defined by the design of the residential premises, their movement is possible only by agreement with the supervisory authorities.

Disabled gas stove

During the repair in the kitchen or just when moving furniture, the gas stove must be turned off. At the same time, operational norms and rules must be observed.

Legislation

Housing owners and responsible tenants are responsible for the correct and safe installation, connection, disconnection and operation of gas equipment in accordance with Article 210 of the Civil Code of the Russian Federation.

Details of the disconnection of gas equipment are covered in the Building Standards and Rules Gas Supply 2.04.08-87. If you decide to carry out a shutdown on your own, you need to attract qualified specialists certified by Gas Supervision and having a certificate.

Safety regulations

Leakage of domestic gas can cause a fire. When gas and air are mixed in certain proportions, an explosive mixture is formed. The slightest spark is enough to cause a strong explosion, which could lead to human casualties and to the destruction of the building. Inhalation of household gas can also lead to severe poisoning. Therefore, the following requirements for the safe handling of gas equipment should be strictly observed:

• Disconnect the kitchen completely, exclude the use of any self-powered electrical appliances, including smartphones.
• Open windows completely.
• Turn off the tap on the inlet pipe, disconnect the stove from the mains by removing the plug.
• Prepare a blank. It is possible to use a bottle cap of suitable diameter.
• Prepare a soap solution in a small container.
• After disconnecting the fitting, insert the plug immediately.
• Check for leaks by lubricating with soapy water.
• If whistling sounds, bubbles, or gas smell are detected, an emergency service should be called immediately.

When connecting the plate after repair, ALL connections should also be checked.

Tools and equipment

Fittings, hoses, gaskets for gas stoves have a long service life, so you should not save on their quality. You should buy them only in well-known specialized stores. Buying parts of unknown origin from your hands can lead to an accident. Bronze products have the best quality, safety and service life; hoses should be made of reinforced rubber with a yellow strip.

Gas key

As tools, you can use adjustable pliers, a universal gas wrench or special No. 1 and No. 2. When installing gas stoves connected to the mains, a special dielectric insert in the pipeline is used. It eliminates the leakage of current through the steel pipes of the gas main.To seal the joints, a linen tow on paint is used, as well as more modern materials - FUM tape or Teflon thread.

Progress

First of all, you should close the crane on the riser. Further:

• To fix a nut on the crane with a key No. 2, to tighten a captive nut of a branch by a key No. 1 and to smoothly turn.
• Lubricate the nozzle hole with soapy water, there should be no bubbles.

Gas stove shutdown

If possible, the valve should be left old, it is better to involve a specialist to install a new crane.

Next, with a gas wrench, unscrew the nut on the flexible eyeliner. If the plate is not changed, the nut is left. Next, unscrew the coupling on the nozzle. Over the years of operation, it can “stick” to the pipe, then it is cut with a hacksaw or angle grinder. Next, you need to move the plate from the wall and ensure constant ventilation of the room.

Stub installation

During operation, the inlet pipe from the gas line will need to be reliably plugged. Special plugs with rubber or plastic gasket can be bought at a plumbing store.

1/2 inlet pipe plug

After installing the plug, its tightness is checked with soapy water. If bubbles are found, remove the plug and seal the threads. The valve is wrapped with a piece of film or non-woven material during repair work. This will prevent dust or paint from entering it.

DIY gas control gas stove

Gas control is the household name for the safety system of gas appliances. It interrupts the supply of domestic gas when the burner flame goes out. All burners and ovens are equipped with such systems.

The system consists of a thermocouple that generates an electric current under the influence of high temperature, and an electromagnetic shut-off valve, structurally combined with a faucet - a regulator for supplying a gas burner.

Gas Control System

The system works like this: when you press the handle of the crane - regulator, the electromagnetic shut-off valve opens mechanically. The gas is ignited, the sensor heats up from the flame - a thermocouple, it starts to generate enough current to keep the valve open. In the event of a cessation of combustion (gust of wind, spilled liquid, etc.), the temperature of the sensor drops, the generated current becomes insufficient and the valve activates, cutting off the gas supply.

The scheme of the gas control system

During any repair of gas stove assemblies:

• Close the valve on the inlet pipe.
• Turn off power supply.
• Remove pets, children and adults not participating in work from the premises.

A sign of a malfunction in the gas control system is the fading of the burner after releasing the valve handle. The cause may be a malfunction or loss of contact of the thermocouple, as well as a breakdown of the electromagnetic valve itself. The valve cannot be disassembled and repaired; it must be replaced as a whole.

The fault is determined by consistently checking the components of the system. First, inspect the thermocouple. It happens that after a long use it "burns out".

Burnt thermocouple to be replaced

Such an item must be replaced. However, if there is no visible damage, you can try to strip the contact at the point of attachment to the solenoid valve.

If stripping the contact does not help, the thermocouple will have to be replaced. For cookers of well-known brands, such as Indesit, Hanza or Kaiser, original spare parts are quite expensive. It is quite possible to replace them with suitable electrical parameters (first of all, the output current) and connecting dimensions, like universal Chinese products. If the fastening nut does not fit, some home craftsmen remove it from the old thermocouple, make a cut with a file and put on a new one. Absolute tightness in this connection is not required, and such a modified nut will provide electrical contact.

Setting up a thermocouple solenoid valve

If the thermocouple is connected to the solenoid valve not with a copper tube, but with a flexible cable, then first of all, check the contact next to the burner. If the cable is burned or melted, replace it. If there is no visible damage, it is necessary to remove the connector and strip the contact of the thermocouple with a fine sandpaper or file.

Fixing a thermocouple with an old nut

If stripping does not produce an effect, the thermocouple will have to be replaced.

Electric ignition and its repair

The electric gas ignition system makes using the stove easy and convenient - the hostess does not need to keep matches or a lighter ready. In addition to convenience, this system also increases the safety of using the stove - ignition occurs simultaneously with the start of gas supply. Such stoves require connection to power supply.

Electric igniter

Over time, electric ignition may fail. The most common causes of problems are:

• breakdown of the arrester tip during wiping or cleaning the stove;
• contamination of the tip with soot and food particles.

First, rinse the tip without applying much force with a soapy solution or other detergent. Next, you need to wipe it dry with a paper towel or soft rag.

If you failed to repair the ignition by rubbing it, you will have to replace it. To do this:

• disconnect the stove from the power supply;
• shut off the gas supply;
• disconnect the stove from the gas line;
• remove the top panel (or the bottom panel of the oven);
• with pliers or a wrench, unscrew the nut securing the arrester to the bracket.
• replace item.

Assembly and connection are carried out in the reverse order. Minor repairs of a faulty gas stove can be done by yourself. The main thing is to strictly comply with safety requirements and not try to repair valves and burners. Serious gas stove malfunctions can only be repaired at an authorized repair center.
