Previously, almost all household appliances belonged to stand-alone. However, progress does not stand still: now you can find many items of built-in type.
Vitroceramic hob
The hob for many users was the hob - in fact the same stove, only smaller. This technique can be gas, or maybe electric. Among the latest options, users give preference to glass-ceramic models, not only powerful, but also with an attractive appearance.
Creative surface design
A gas hob is no different from the lack of a built-in oven than an ordinary stove. To connect it, you need only a constant source of gas and a hose for supplying fuel. The panel is easy to put on a pedestal. It is compact and does not take up much space, which makes the equipment indispensable in small-sized kitchens.
Gas hob
Like any item of household appliances, the hob is subject to various kinds of malfunctions. One of the most common is non-working burners. The occurrence of such malfunctions is characteristic of both electric and gas models. Repair can be carried out independently, or by calling mechanics. However, often masters can take a lot of money for simple work in general.
We will understand why such problems arise and how to repair the hobs with your own hands. Each type has its own characteristics, which will be considered.

What causes the problem?
The situation when the ignition system fails is one of the most frequent. The situation applies to both electric and gas hobs. It occurs in panels that have been in operation for five years. For new ones, this is rather an exception than a rule. The causes of failures may be as follows:
- The operation of electric ignition is broken.
- Weak gas control.
- Gas burner clogged. It can be both the remnants of cleaning products and the remnants of food that fall under the lid of the gas burner.
- The surface of the panel is flooded.
- The button to turn on the current or gas is faulty.
Next, we consider the main causes of ignition problems and how to resolve them.
Ignition system issues
Suppose the hob is connected to the mains, but the hob power button does not work. This happens if the power supplied through the wires of electricity is not enough to work. This happens in homes with poor power supply, or when the hob is connected to a tee. In this case, a voltage stabilizer is useful. When you connect electrical appliances to it, it begins to evenly distribute energy between all the equipment. Thus, it is possible to provide 220 volt panels necessary for operation. Also, a voltage stabilizer will minimize the risk of burning electrical appliances in the event of a power surge or short circuit.

The following symptoms may indicate problems:
- When the button is pressed, the hotplate does not turn on.
- The candles sparkle when turned on, but the burners do not light up.
- The panel turns off after releasing the start button.
Repairing an electric hob can be done in several ways.
Plate cleanliness
Contamination of the stove, especially the ignition mechanism, is the most common cause of jamming of buttons. It occurs after sprinkling or boiling food during cooking. Over time, the mud freezes, clogging the mechanism and the burners themselves. Solving a similar problem is quite simple: wipe the surface and clean the nozzle with a needle. So the burner will be freed from the burnout and other particles clogging it. Once everything is dry, turn on the panel again and check whether the stove will work.

Burning candles
When the candles sparkle in yellow or orange, this is a sure sign that the power supply is broken. If you notice sparkling candles, then in this case, you should disassemble the panel to get to the electronic filling of the device. You must act as follows:
- Unplug the hob.
- Using a screwdriver and other tools at hand, remove the top cover.
- Now disconnect the contacts from the power supply.
Thus, you can replace the block: just take the broken one and show it to the store sales consultants who will offer a working part.
You can make sure that the problem is with the unit by turning on the hob in the dark. If the spark is blue, then the unit is operational, if yellow or orange - it requires replacement.
Sparking with yellow or orange light can also be associated with oxidation of the candlestick. The problem is solved by replacing the defective part. It is worth noting that such malfunctions are extremely rare and occur only where for a long time the moisture concentration in the air exceeds all necessary standards.
This can also happen with transfusions that are too frequent. Particles of water can penetrate inside the panel, which entails droplets falling on wires or microcircuits. In this case, quick and high-quality drying will help, otherwise the stem of the candles may oxidize. Otherwise, the wires will become coarser and can easily break, so you have to completely replace the electronic filling of the hob.

Gas control repair
Such problems are mostly characteristic of hobs used for a long time. The burners either light up too long or go out after releasing the handle. The cause of this kind of malfunction is a clogged thermocouple. This mechanism is responsible for supplying gas to the burner. If the burners go out quickly, disassemble the burners, find the thermocouple and clean with the help of improvised items. An ordinary wire, needle or knife will do here.
If the measures taken do not bring the desired effect, then perhaps the cause is a malfunction of the thermocouple or the solenoid valve. These parts will have to be replaced.

DIY induction hob repair
The induction model is considered one of the most high-tech and advanced in the world market. However, she is also not immune from all kinds of problems. Often the quality of heating of a particular dish depends on its type. So, the burner does not turn on. Problems may be as follows:
- They turned on the panel, but as soon as they released the button, it went out. In this case, the cause is not a breakdown of the ignition. Many induction hobs have a protective mechanism that responds to the diameter of the cookware installed on the burner or its type. When the cookware is removed from the burner, it also turns off, and in this case nothing extraordinary will happen.
- Interruptions when turning on the burners. This may be due to surface contamination. The most common cause of such problems is salt.Wipe the surface with a damp cloth and dry the hob, after which the device will be completely at your disposal.
- The hob does not turn on. In this case, it remains only to disassemble the panel and check the contacts. If one of the wires or fuses is blown, you will have to replace these parts with serviceable ones. Postings, if they are torn, you can solder yourself, but it is better to entrust such delicate work to professional masters.

Repair gas hob
In this case, you don’t have to figure out the reason for the sudden breakdown of the hob, since gas models have a fairly straightforward and therefore intuitive design. Here, manufacturers use far less electronics and microcircuits, so repairing a gas hob, if it does not light, will be extremely simple.
If the burners do not light up or burn very weakly even at maximum settings, we repair the equipment according to the following scheme:
- Check burners for clogging, especially electric ignition.
- If there is a large stagnation of liquid or debris, try to clean everything with a needle or a thin sharp stick.
In most cases, this will be sufficient. If the measures taken do not lead to the resumption of the equipment, check the electrical circuit for serviceability.
The reason that the hobs of the hob do not burn may also be a delay or blocking of the gas supply. In this case, no repair is required: just check the gas pipe.
If gas continues to flow while the faucet is open, but the burners do not ignite, clean the nozzles from debris or moisture. You can do this with a long needle or with a cotton swab. To do this, follow these steps:
- Remove the cover from the burner.
- Carefully disconnect the burner from the stove.
- We insert the sharp tip of the needle, the straightened paper clip or wire into the nozzle and carefully remove all the stagnant debris: food particles, burnout and other contaminants.
Now it remains to check how well the gas supply works. Remember: you can’t carry out a check without putting the iron cover on the burner in its place. The main thing here is to carry out prophylaxis in time and prevent boiling over of the prepared food, and most importantly, do not fill the nozzles while washing the stove, when the remnants of the cleaning agent settling under the burners cause clogging.
