At the beginning of the path to recovery, you should correctly determine the cause of the breakdown - this process is called diagnostics. In most cases, electric ignition does not work due to a faulty unit, oxidized contacts, or a burnt button. After reading the article to the end, you will learn: how to correctly diagnose a broken unit and safely repair a gas stove yourself.
Why did the electric ignition stop working?
1. The unit (high voltage pulse converter) - the main element in the circuit - is faulty. Induces high voltage pulses on the arresters. Consists of capacitors and induction coils. Parts cannot be repaired or replaced. Symptom: There is no spark on all burners.
2. The button or its contacts are faulty - the second element in the circuit. Electric ignition trigger. Consists of a housing and two contacts. The reliability of the contacts is not fully guaranteed; they oxidize, melt, and are destroyed. Symptom: does not spark when you press the handle.
3. The spark gap (spark plug) is faulty - it releases an electrical pulse of short duration opposite the burner fire hole. A crack in the insulator disrupts the stability of the spark and deflects it to the side. Symptom: One burner does not light.
It is worth mentioning the negative effects of moisture. If, after wet cleaning the stove, the electric ignition clicks spontaneously, there is no need to panic. Disconnect the device from power for 2-3 days, or until completely dry. You can speed up the process with a hairdryer by directing a stream of hot air under the faucet handles.
Why does the gas boiler not work?
A gas boiler is a complex technical device equipped with a protective group of control sensors that should protect against breakdowns during emergency situations. But no manufacturer gives a 100% guarantee against malfunctions.
A breakdown creates a potential danger not only for the residents of the house where it is installed, but also for their neighbors, since there is a threat of a gas explosion due to a leak. Therefore, at the first sign of a malfunction, it is urgent to repair gas boilers, and, in extreme cases, replace them. But in some cases, the reasons can be found on your own, which we will discuss below in the article.
4 types of breakdowns
Equipment specialists classify breakdowns into 4 types:
- Temporary and final. The first ones appear during a malfunction, for example, when there is no gas supply or an unacceptable decrease in pressure, and then, after eliminating the root cause, the equipment operates normally again. The second are malfunctions that cannot be eliminated by turning the lever or other simple actions. That is, the gas boiler requires serious repairs.
- If the boiler fails for the first time, then the failure, regardless of the cause, is considered primary. If it is not eliminated, and after a while new faults appear, then they are already classified as secondary, since they appeared against the background of the first fault.
- Obvious ones - for example, the gas power switching regulator has broken down, and non-obvious ones - for example, when the fault is “hidden” in the heat exchanger.
- Sudden - when the boiler suddenly stopped working for no apparent reason and gradual, which can also be classified as secondary.
Next, we will look at common faults and their possible causes. Let us immediately note that it is better to entrust the repair of a gas boiler to a specialist who will give a guarantee for his work.

Common breakdowns and causes of their occurrence
5 reasons why the boiler does not turn on when ignited
Repair experts have identified 5 reasons why the boiler does not turn on. The first, the most easily correctable and does not require repair, is that the equipment is not plugged into the outlet or the power supply is turned off.
The boiler may not turn on due to blown sensors and fuses that require replacement. As a rule, this happens when there is a short circuit in the wiring. The devices are part of the so-called “safety group” and take over voltage surges, protecting the main systems from breakdown. But sometimes the surges are so strong that even fuses cannot help, and then the varistor fails. Upon inspection, the master will immediately see this.
The third reason why the boiler does not turn on is a clogged coarse filter. In order to bring it back to normal, the equipment must be disconnected from the power supply and the gas must be turned off.
If the batteries in the thermostat are dead or the room sensor is accidentally turned off, the equipment may also not turn on. The fact is that all gas boiler systems are combined into one circuit; a failure even in one link is critical.
And the last, fifth reason why it is not possible to warm the radiators in the house is the failure of the pump that pumps the coolant. As a rule, this is due to stagnant air, which causes failure in the rotor.
The flame goes out in the open combustion chamber - check the draft and chimney
The first thing you need to check in an open combustion chamber is the presence and type of draft. You can check its presence or absence using a special device or a piece of paper. If you do not have a special device, hold a piece of paper to the smoke or ventilation duct. If there is a draft, then the sheet of paper will be pulled inward; if the sheet of paper blows out or it does not move, then there is no draft. We do not recommend checking the presence or absence of draft with an open fire, since only an employee of a specialized organization can verify the complete absence of gas contamination in the room where gas-using equipment is installed using special instruments such as a gas analyzer or a gas leak detector.
If there is no draft, first of all you need to check the chimney and clear it of blockages. If, on the contrary, the air flows are very strong, they need to be adjusted using dampers. The chimney can not only become clogged with soot, but also freeze up in winter.
5 reasons why the burner does not work in a turbocharged boiler
A turbocharged boiler is distinguished by the fact that there is a fan inside the device, which provides draft for gas combustion and forced smoke removal. The experts have identified 5 reasons why the burner may not ignite in a closed combustion chamber.
The first reason is power surges, which can cause breakdown of the circulation pump. If network fluctuations occur too often for reasons beyond the homeowner’s control, then installing a stabilizer will help. But let’s immediately note the second reason, also related to the circulation pump - when the phase and zero are reversed during connection. A specialist will help correct the situation.
The third reason is that the igniter may be faulty. To check, you need to check the condition of the ignition electrodes. The fourth reason why the burner in a gas boiler does not light is due to a malfunction of the draft sensor. To make sure the assumption is correct, you need to ring the sensor. And the fifth and final reason may be a broken piezo ignition button.
2 reasons why the boiler starts to smoke
Sometimes after ignition, soot starts coming out of the combustion chamber. It occurs due to the fact that the gas does not burn completely. This happens when there is too little air in the chamber. To increase it, it is necessary to equalize the flow when the burner is lit. The required amount of air can be easily determined by the flame. If there is enough of it, then it has an even bluish color, if there is not enough, then the fire will be red with yellow dots, if there is too much, it will vibrate and make a lot of noise.
The second reason for the appearance of soot in the chamber is clogging of the burner with combustion products. It is enough to clean it so that the flame lights up again as usual.
2 reasons why the fire goes out in the summer and the flame comes off the nozzles
Despite the fact that in summer there is no need to heat the house, draft must be maintained in the boiler. It often happens that in the summer a fire can spontaneously go out for two reasons: The draft sensor is broken - it needs to be replaced. There is too much temperature difference in the house and outside. The problem can be solved by heating the exhaust pipes.
For the same reasons, another malfunction occurs - flame separation from the injectors. But, in addition to traction, it may be necessary to replace the injectors themselves.
4 reasons why the coolant does not heat up
If the fire in the boiler is burning, but the batteries remain cold and there is no hot water flowing into the tap, this means only one thing - the coolant is not heating up. The masters have identified 4 reasons why this happens.
- The first is that the boiler settings are not selected adequately for the season of the year. It is enough to adjust them to heat up the batteries.
- Second, the pump does not work. See the reason above.
- The third is the accumulation of scale in the heat exchanger. It can be removed using special means.
- The fourth is breakdowns of temperature sensors.
If the radiators are warm, but there is no hot water in the tap, then the reasons may be a malfunction of the three-way valve, a leak in the internal systems, or in the low-quality coolant itself, which caused blockages.
Additional overview of three types of boiler failures
If the device makes a suspiciously loud noise or whistles, then the main reason is the accumulation of scale or too much air in the area of the nozzles. If the boiler systems wear out before the manufacturer's warranty expires, then perhaps the reason is due to clocking. The fact is that the systems work to maintain a predetermined coolant temperature. When it is reached, the boiler turns off, and as the coolant cools down, it turns on again. But if the working fluid cools too quickly, then the on and off cycles also speed up. The problem can be resolved by installing additional thermoregulation devices. Overheating of the boiler is usually caused by the accumulation of scale and blockages.
Why you shouldn’t fix boiler problems yourself
Most modern gas boilers are equipped with digital displays, which themselves indicate a malfunction using a code. By the number you can immediately determine the problem. But this does not mean that you need to disassemble the equipment yourself, risking breaking it at best, and causing a gas leak and explosion at worst.

Electric ignition does not click
A common and very common root cause of failure is a burnt-out radio component in the ignition unit. The unit is powered from a 220V network. After pressing the button, current is supplied through the switch to the transformer, resistor and induction coil. The formation of a spark is carried out by the voltage supplied to the primary winding of the transformer. After pressing the button, the transformer is discharged and a discharge is sent to the ceramic spark plug. If the converter is destroyed or the conductive paths in the ignition circuit are damaged, spark production stops. Repair comes down to replacing the entire unit, since the parts are filled with epoxy resin and are difficult to solder.

Electric ignition does not light one burner
Automatic electric ignition of burners is made up of numerous units. The most important element is the spark gap (spark plug in white ceramic). A violation of the insulation of the armored wire or a crack in the ceramic will disrupt the operation of the entire device - the spark on one burner disappears. A crack or chip on the insulating surface diverts the spark to the side (pierces the housing). The defect is clearly visible in the dark. It is impossible to restore the integrity of the insulator using twisting or electrical tape; the only option is replacement. The candle is installed in the hole and secured with a cotter pin to the gas burner; it is connected to the block in 100% of cases using a male-female connection. Instead, only the original spark plug is installed; the analogue has a different seat and electrode height, which is the main criterion for correct operation.

Own schemes
We are ashamed to call the electrical circuits for igniting a gas stove complex. Radio amateurs make it easier. The getinax board is etched and the necessary elements are soldered in. The initial composition of the electric ignition of a gas stove is provided by a ready-made transformer and a button discussed above.
An experienced engineer can usually improve upon this from the manufacturer. The Internet provides an interesting circuit for electric ignition of a gas stove, formed by a triac, strikingly simple.
Electric ignition no spark (does not ignite gas)
The gas is ignited by pressing the microswitch for electric ignition before opening the burner tap. Microswitches are located under the handles of the stove and have two movable bridge-type contacts. Under the influence of moisture and heat, a non-conducting film is formed on the contact pair. The oxidized layer has low electrical conductivity; therefore, when you press the button, the circuit does not close. To repair, remove the oxide using ethyl alcohol and a toothbrush. The microswitch cable has 4-5 power buttons. The button body is separated by latches. Work is carried out on a de-energized stove.
Electric ignition does not turn off (does not turn off)
During prolonged use, spontaneous activation occurs due to contamination of the buttons with grease or food. Residues of food and water fall on moving mechanisms. The return spring is not able to overcome the resistance and return the mechanism back, so the ignition continues to click after turning on the burner. In this case, maintenance of the rotating mechanisms of the crane and push button units should be carried out. Remove the plastic handles (turntables). Soak a cotton swab in ethyl alcohol. In the holes under the handles, carefully wipe each button. Grease is removed with a dry cloth. Soak the handles in soapy water and rinse under running water.
