DIY gas stove repair

The most common breakdowns of gas stoves, which are used to contact our workshop, are as follows: weak or no gas flow on the burner; jamming or tight adjustment of the gas supply valve; gas smell when using the stove; switching off or not switching on the hotplate; flame smoking or different heights and much more.

Let's look at the signs and causes of plate breakdowns, the method for eliminating them with our own hands.

Gas leak. Leakage of domestic gas usually occurs in threaded connections of gas fittings, as well as in case of incomplete combustion of the gas or, in another way, the separation of the flame. You can find a leak using a soapy solution or a similar smell, for more details in this article: How to find a gas leak in a household stove. Repack the leak. Change the paronite gasket. If the gas leaks due to wear and an increase in the pitch of the thread, you should wind the Fum tape on the thread.

Crane turns tight... Stove breakage is inherent in gas stoves that were operated without preventive maintenance. To return the valve to its normal working condition, it must be lubricated. The valve should be lubricated with graphite grease.

The valve is lubricated according to the following scheme. 1. The common valve on the lowering to the stove is closed (central gas supply valve to the stove). 2. Removing the decorative panel of the hob to access the taps, if you have a hob, then you will have to remove the hob. 3. At the faulty valve, two shank screws are unscrewed, and a bronze plug is obtained. 4. The plug of the tap is not cleaned with a soft cloth. 5. Dip the pad of the finger in graphite grease and apply to the valve plug, lightly touching it. Make sure that no excess grease gets into the plug and valve openings.

High red flame... This breakdown is often found on old Soviet-era gas stoves. Modern stoves and hobs are designed so that the flame smokes only due to the deformation of the burner, so if you are faced with this problem and you have a modern stove in your kitchen, it is worth looking and buying new burners.

Further information for Soviet plates. The reason is caused by the lack of the required air for the combustion of the gas. Poor combustion of gas with a lack of air mixture is characterized by a high red flame, which leaves a black smoke mark on the heated dishes. To repair the gas stove, try adding primary air to the venturi. This is done by raising the flap on the injection burner. If, after raising, smoking does not go away, then we conclude that there is a large amount of supplied gas, that is, a nozzle is installed for a different type of fuel.

Gas combustion noise and flame separation from the burner. This failure occurs due to an air imbalance, excess air or due to an increased pressure of the supplied gas. If only one burner is faulty, close the aforementioned damper. If a malfunction appears in all burners, most likely a problem with the gas pressure.

It is impossible to imagine any kitchen without a hob, be it an electric or a gas stove, since it is on these units that the cooking process takes place. But unfortunately, these devices fail over time for various reasons. Repair gas stoves, fix all kinds of breakdowns and carry out maintenance qualified gas service specialist... But there are minor faults in which you can fix the gas stove on your own. So, you can repair a gas stove with your own hands with the following malfunctions:

  • one or all burners do not light up;
  • electric ignition does not ignite the gas;
  • after the gas is ignited, the burner goes out;
  • the oven lid is not covered.

This malfunction can be caused by a number of reasons:

  • clogging of the gas supply nozzle;
  • failure of the ignition plug;
  • damage to the insulation of the wire going to the candle;
  • faulty electric ignition control unit;
  • malfunction of the power button.

The nozzle (jet) of the unit can become clogged from food, detergent powder or gas combustion products. In this case, self-repair of a gas stove is very simple: you need to remove the burners and clean the nozzle a wooden toothpick (do not use metal objects such as a paper clip or needle for cleaning).

If you cannot clean the nozzle without disassembling the stove, then you should remove the top panel of your device by unscrewing a few bolts. For a good cleaning of the jet, it can be unscrewed.

Before disassembling the gas stove, you should disconnect from it the power supply (voltage for the candle - 220V), which is required for electric ignition. This malfunction of the electric ignition device can affect both one burner and all at once. If the spark does not skip on one burner, this means that the ignition plug (electrode) is out of order. On it, in the ceramic insulator, a crack may form, as a result of which the electrode stops working correctly.

To repair a gas stove with your own hands about replacing a candle, it is enough to remove the burners, open the stove cover (by unscrewing a few bolts), and change electrode on new.

Also, a frequent malfunction of the electric ignition on one burner can be wire damagegoing to the candle. To check this, press the ignition button with the unit cover open. If the wire is “punctured” in any place, then you will see a spark slipping in this place either on the body of the device or on the foil that covers the oven.Repair of electric ignition of a gas stove with a damaged wire consists in replacing it with a new one, or it must be moved to another place so that there is no “breakdown” to ground.

In the case when the electric ignition does not work on all burners, including in the oven, this means that the ignition unit is out of order. To repair the autoignition, you need to replace the unit with a new one after removing the top panel of the device.

The process of repairing the electric ignition of Darin's gas stove is shown in detail in this video:

There are times when a properly working gas stove suddenly starts to present surprises. For example, you turn on the gas supply, it lights up, and after releasing the handle, it immediately goes out. Such symptoms speak of thermocouple faults - a sensor that turns on the supply of a combustible mixture.

A thermocouple works in the following way: when heated, it generates an electric current, which magnetizes the solenoid valve. The valve, in turn, opens and the gas flows freely into the burner. If the thermocouple stops heating, the electrical impulse is lost and the valve shuts off the flow. Thus, if, after opening the valve to turn on the gas and ignite it with an electric candle, combustion stops immediately, this means that the electromagnetic valve has worked and cut off the supply of the combustible mixture.

It is quite simple to repair a gas stove with such a malfunction.

    First, you will need to remove all the handles and the top panel of the stove by unscrewing the bolts on the sides of the lid and under the burners (stove designs may be different, respectively, and the location of the fasteners may differ).

  • After unscrewing the fasteners, remove the top cover of the unit.

  • After disassembling the unit, you will see two protruding parts near the inoperative burner. White is the ignition plug, and next to it is the thermocouple.

  • A wire goes from the thermocouple to the connector, from which it should be pulled out. Disconnect the gas control sensor from the burner.
  • After removing the non-working element, install the new one purchased in advance.
  • Thus, it is possible to repair the Hephaestus, Ardo gas stove, Brest and Hansa stoves if the thermocouple fails.

    Also, do not forget about safety precautions: before you repair the gas stove, you should disconnect it from the mains.

    Sometimes a broken button can be the cause of a spark plug failure. This malfunction during the repair of Gorene gas stoves or other brands can be determined by throwing the wires (after removing the top panel of the device) to another button gas stoves. If the ignition works when the burner tap is opened, then the faulty button must be replaced.

    The most common oven breakdown is poorly closing the oven door. It occurs most often when there is a small child in the house who simply sits on the open door, as a result of which the brackets holding this part bend and do not fulfill their function of pressing the sash.

    To repair the oven of the Indesit gas stove, Brest 1457 or the Flama stove, you will need disconnect the door from the unit... To do this, you need:

      Since the door is held on hinges equipped with latches, they must be bent on both sides of the unit.

  • After that, you must carefully close the door until it stops in the latches.

  • Next, you need to pull the door slightly towards you and up, after which it will easily detach from the stove.

  • To get to the brackets when repairing the Gorenje gas stove or when repairing Darin's gas stove, as well as the Brest unit, it is necessary to remove the side walls of the oven. Removing the sidewalls, you will see brackets, which are responsible for the clamp.

  • The brackets must be removed from the oven of the gas stove and visually determine where they are deformed. Using a hammer and pliers, you can try to straighten out the deformed places.But in the event that this part is broken, it must be replaced with a new one. The stores sell different types of spare parts for repairing the oven and stove. Select the brackets that match your gas stove model.

  • Summing up, we can say that only the above malfunctions can be eliminated with your own hands. All types of troubleshooting of gas stove malfunctions associated with disconnecting gas supply pipes and hoses must be carried out by a gas service employee, after which he draws up an act of repair performed. The same rule applies to connecting the gas stove to the mains - it must be carried out by a specialist. To carry out self-repair, it will not be superfluous to get acquainted with how the gas stove is arranged.
