Previously, gas stoves were produced without electric ignition. In fact, this is not an obligatory function, but its appearance greatly facilitates the process of using a household appliance: there is no need to buy a special lighter or matches. However, over time, a function often fails. We will figure out what to do if the electric ignition device does not work on the gas stove and whether the breakdown can be fixed on its own.
Electric burner
Symptoms
Electric ignition of gas stoves may break unexpectedly: the switch turns, the gas exits, but there is no spark. Failure of an additional function can occur for completely different reasons.
But first of all, it is worth determining that the electric ignition function of the gas stove has really failed. The following symptoms may indicate this:
- while pressing the control knob or the button for the burner, the electric ignition function does not work;
- automatic functions of the device operate in a continuous mode, sounds similar to clicks are noted. In this case, there is no spark, the gas stove simply does not ignite;
- when you release the handle or button, there is no system shutdown;
- the device works even without pressing a button;
- there is a knockout of the circuit breaker in the area of the apartment shield when the device is turned on;
- the presence of a malfunction can be established according to the piezoelectric ignition and electric ignition scheme, it can be closed.
How the function works
The electric ignition system is provided in gas stoves. Its main purpose is to kindle the fuel that comes from the burner divider. The electric ignition device can be of two types:
- Automatic
- mechanical.
Auto ignition has special piezoelectric elements, which, while turning the switch on the panel, ignite the air-gas mixture. When using a mechanical device, you must press a special button. When pressed, a spark is supplied, from which the gas ignites and ignites.
The principle of operation of electric ignition looks like this:
- when the user presses the button, voltage is applied to the capacitor region;
- after that, charging of the capacitor begins;
- then there is an increase in the level at the thyristor;
- as soon as it reaches the permissible limit, the discharge of the capacitor begins;
- at the output of the device, a voltage is manifested, due to which the arrester is activated;
- the generated spark ignites the gas.
Electric ignition work
Despite the fact that the process looks complicated, it happens in seconds. The supply of spark always falls on the area of the burner, which at this moment is in the on state. In obsolete products, a spark was supplied to all burners, but the ignition occurred only on the one on which the gas supply was open.
The electric ignition is supplied from an electric network with a voltage of 220 volts. His work also depends on voltage drops, which can occur quite often. If a power surge occurs, a clicking sound may appear, this usually indicates a malfunction of the electric ignition device.

Breakdown reasons
Many owners of household appliances often have a question, why did electric ignition stop working? The failure of this function can occur for various reasons, among which it is worth highlighting:
- lack of spark on the electrodes;
- moisture or grease on the surface of the inside of the system or on the candle;
- breakdown of electric ignition can occur due to the appearance of a crack or due to damage to the insulation of the candle from the ceramic base;
- burned out transformer - spark generation unit. Usually when you press the button, there is no spark. It can be done independently, but experts recommend changing the part to a new one;
Spark Generation Block Check
- the presence of oxidation of the contacts of the power button or the appearance of a layer of carbon deposits on them, which was formed as a result of a short circuit.
Sometimes minor malfunctions can result from wet cleaning of the hob. This usually happens due to moisture entering the interior of the appliance. In order to eliminate everything, it will be necessary to carry out preventive measures: perform cleaning of contacts, drying of candles. All these actions can be carried out by any user without knowledge and experience in this matter.
Failure may occur during wet cleaning.
It happens that only one burner does not light. This may be due to a malfunction of the high voltage wire that goes to the ignition electrode. Possible failure of the ignition device itself, or failure of the block channel.
Breakage can sometimes occur when cleaning the hotplate.
Repair Features
You can repair the electric ignition device yourself, but you must first conduct a thorough inspection of the device. It is important first of all to establish the cause of the breakdown, the degree of difficulty. If the malfunction is simple, then you can fix it yourself.
Ignition button
If the electric ignition function does not work well, the repair process for all models of household products is usually performed the same way. For all gas stoves, this function is arranged stereotyped.
It is advisable, before starting the repair process, to carefully study the device of the stove: you can find information on the Internet or study the attached instructions for use. If you know how the device works, it will help to perform high-quality and correct repair.
Electric ignition unit
Electric ignition repair depends on the type of breakdown. To understand how it is made, it is worth considering the types of breakdowns and their elimination:
- The burner should be ignited using matches or a special lighter. Carefully inspect the type of flame: it should be even, bright, should be distributed around the entire circumference of the divider. If a yellow color is noted, then this will indicate incorrect indicators of the ratio of gas to air. To fix this problem, you need to clean the nozzle or replace it completely. Perhaps the cause of the malfunction is the clogging of the holes of the divider or the presence of moisture in them. It is also advisable to carry out preventive measures: blow through all the holes, remove the burner body and carefully examine it;
Normal flame
- usually all electrodes and switches are connected in parallel. Each electrode is powered from a single ignition unit, but they are turned off and on by various buttons. In order to establish that it was this button that stopped working, and the control unit is in normal condition, it is necessary to check the next ring. If the gas ignites, it is necessary to repair the button. It turns out that the remaining elements in the device are in good condition;
- sometimes cracking may occur in the ignition system. In these cases, a contact check is recommended.This problem can occur when they are stuck from plaque from fat, and a layer of soot may appear on them, which adversely affects the work. Before carrying out repairs, the stove must be disconnected from the network, then disassembly is required. All contacts should be well cleaned or dried using a regular hair dryer. However, it is necessary to comply with established safety requirements, this will help to avoid dangerous injuries.
When to contact a specialist
To repair electric ignition, you do not need to have much experience and knowledge, even inexperienced users can handle this.
However, sometimes it is necessary to conduct a thorough check and diagnosis of the device. A flashlight and a simple screwdriver, it certainly will not work. For this reason, it will be necessary to call a specialist. Of course, the services of a master can be expensive, but sometimes a breakdown in electric ignition can occur as a result of a serious reason, which can be a threat to humans.
Sometimes repairs should be entrusted to professionals
In any case, before starting to repair the electric ignition device, it is worthwhile to carefully study the circuit diagram of the device. This will help to fix the problem much faster, without harming the device. It is important to pre-check the combustion, sometimes it can be the case in the burner or in other components.
