Do-it-yourself electric ignition unit repair

I know for sure that if the electric ignition unit stops working, then it’s not necessary to buy a new one right away, you can repair it yourself, but I don’t know how.

We will divide the task into several small ones, based on this we will carry out diagnostics and find out if we are suitable for repair or not. Electric ignition consists of a power cord, a high-voltage converter, a start button, a sparkling contraption (I’ll call it conditionally a spark) and a wire (from the button to the converter and from it to the spark). Accordingly, what we can repair ourselves:

1 Make sure that all the wires are in good condition, they have not fallen off, they are not bitten, the power supplies are energized, the mass has not oxidized, in general, we will ring the circuit. - Anyone who has a battery and a light bulb for a flashlight or a tester for advanced people can do this. If these words already make you wary, it’s better not to worry, go to the master, because if this material was not learned at school, then I won’t help you with my advice either.

2 High-voltage converter - I don’t know how it works, I can assume that there is a step-up transformer there - it is not repaired at home - here I would go to the master.

3 Sparks, if they crumble - then a direct road to the store, if they are intact, then they cannot not work.

Conclusion: If you have mastered the school physics course “Electricity”, you can start diagnosing and repairing electric ignition, if not, contact a specialist.

Malfunction and repair of internal combustion engine camshafts.

The most common failures of this part are cam failures, camshaft bending, wear of its bearing journals, and an increase in bearing clearances. All these malfunctions are usually indicated by a knock from the valve mechanism, as well as a decrease in oil pressure.

Bearing clearance can be returned to normal by restoring or regrinding the bearing journals of the shaft to the nearest repair size. In this case, the depth of the oil grooves should be increased to prevent oil starvation of engine parts. After completion, the neck must be polished with GOI paste

If the shaft cams have worn out slightly, they can be restored by sanding them. In this case, it is necessary to switch from coarse-grained paper to fine-grained paper. If in some places the cams have crumbled, it is recommended to remove the sharp edges of the metal with the same sandpaper. However, this will help only in case of small chipping (up to 3 mm in length). Otherwise, you will have to purchase a new assembly assembly. In the case of vertical wear of the cams, difficult grinding on a copy-grinding machine is necessary. In the case of a significant vertical development, the cams are repaired by welding. Then they should be sanded. Note that the permissible development of the cams is 0.5 mm. At large values, a decrease in the power characteristics of the power unit is observed. Therefore, in such cases, the shaft is replaced with a new one.

Worn camshaft journals are also repaired by welding. Although there are other ways to restore - chrome plating and remaining. But in any case, the restored parts must be polished.

As mentioned above, the shaft can also be bent. Its permissible value is not more than 0.1 mm. Otherwise, the part will need to be repaired.

You should also measure the gap between the shaft journals and the holes in the supports on the block head. Measurements are made using a calibrated wire.In this case, its maximum value can be 0.2 mm.

Modern gas stoves or gas hobs are equipped with electric ignition. Having studied the principle of work, there will be a chance do-it-yourself electric ignition repair. The electric ignition of gas stoves and hobs is switched on at the moment of turning the gas supply knob to the selected burner or by briefly pressing the electric ignition button. You hear a click generated by the discharge of the electrode on the mass of the burner. At this moment, you can see a spark, like lightning, but in miniature. And people with a heightened sense of smell can smell ozone.

Discharge after discharge follows at intervals of one second, until the gas supply knob is released. If you have an electric ignition button, the number of electric ignition discharges is equal to the number of pressing the electric ignition button. Accordingly, the frequency of discharges in manual mode is equal to the frequency of pressing the button. The discharge is the cause of ignition (ignition) of the incoming gas into the selected burner. But since the spark generation circuit is powered by the mains (electricity), the ignition has acquired the name of electric ignition. In the case when sparking occurs in automatic mode, such electric ignition is also called electronic.

THERE ARE TWO ELECTRIC IGNITION OPTIONS:

1. By pressing and releasing the electric ignition button, a single spark occurs (at the moment the button is released).
2. By pressing the gas supply knob on the burner, continuous sparking occurs at a frequency of one second.

TWO ELECTRIC IGNITION OPTIONS ARE BASED ON TWO ELECTRICAL CIRCUIT OPTIONS:

1. The first option (Fig. 3) is based on the manual charge-discharge of the storage capacitor. Works like this:

(r1- 3.9k, c1- 2.2uFX600V, d1- 1N4007) The circuit is connected as follows: Diode d1 is supplied with mains voltage (Fig. 3.1). By pressing the electric ignition button, you apply the mains voltage to the capacitor c1 (Fig. 3.2). The capacitor is charging. At the moment the button is released, the contact of the capacitor c1 (Fig. 3.2) is connected to the transformer t1, through the contact (Fig. 3.3). The reverse process occurs - the discharge of the capacitor through the primary winding of the high-voltage transformer t1. On the secondary winding of the transformer (Fig.3.t1-1) and (Fig.3.t1-2) an output voltage of about 10 kilovolts is formed. A spark is formed. Pressing and releasing the button repeats the process. The transformer outputs (Fig.3.t1-1) and (Fig.3.t1-2) on (Fig.1 and Fig.2) are marked with number 1. The output (Fig.3.1) corresponds to numbers 5 and 2 (Fig.2). The conclusion (Fig. 3.2) corresponds to numbers 7 and 3 (Fig. 2). The conclusion (Fig. 3.3) corresponds to numbers 6 and 4 (Fig. 2).

2. The second option (Fig. 4) is based on the electronic control of the charge-discharge mode of the storage capacitor. Works like this:

(r1- 300 ohm, c1- 2.2 Mkph600V, d1- 1N4007, d2- 1N4007, d3- 1N4007, r2-1.5 kΩ, r3-30 kΩ, s1-ku202n, )

When you press the electric ignition button, the charge-discharge occurs automatically. Automatic mode depends on the circuit design of the electric ignition.

The circuit works as follows: with a positive half-wave of the mains voltage, capacitor C1 is charged through D2 and D3, with a negative half-wave through D1, the cathode S1 is connected to the “negative” half-wave, and through the resistor R3, a control current is supplied to the control electrode of the thyristor. The thyristor opens, capacitor C1 is discharged to a high voltage transformer, which induces an ignition spark. An output voltage of about 10 kilovolts is formed on the secondary winding of the transformer. By holding the throttle knob down, the process repeats at a frequency of 50 Hz, or roughly one spark per second.

Electric ignition is more common four and six-channel (Fig. 1 and Fig. 2) number 1 indicates the taps for connecting the electrodes on which you observe sparking.In other words, we have four ignition electrodes or six electrodes. The number of electrodes depends on the number of secondary windings of the step-up transformer. If there are two windings, then we have four outputs for four electrodes. If there are three windings of the step-up transformer, we have six outputs for six electrodes.

Electric ignition, which allows you to connect six electrodes, is usually used in gas stoves of a single design with an oven. And as a result, two of the six available electrodes are in the oven and are used to ignite the gas in the oven. The appearance of electric ignition devices can be seen in (Fig.1 and Fig.2). They have some difference, but the circuit design and the principle of operation remain unchanged.

Below is a list of common problems with electric ignition of gas stoves, and how to fix them. This information was accumulated over the years of practice and acquired structural forms. The information will be useful for both beginners and those who are used to repairing everything with their own hands. Below is a list of six points that characterize the malfunction of the electric ignition of gas stoves. Knowing the contents of the items will make it easier to learn the secrets of repair. Each item contains a detailed description of the logical troubleshooting path of the item name. Knowledge will help do-it-yourself electric gas stove ignition repair. Make repairs yourself.

Almost all gas stoves have gas ignition system. when you press the button, a spark gap is triggered near the burner, a spark breaks through and the gas ignites. Of course, this is very convenient (after all, once it was necessary to carry out this entire procedure with the help of matches), only here there is one drawback - the spark generated by this device is single.

Using electronics, you can slightly modify this system and turn it into a multi-spark system.

This electric gas ignition scheme for a household gas stove almost similar to the one shown above, but contains a little more detail - here a thyristor is used instead of a triac.
The circuit works as follows: with a negative half-wave of the mains voltage (pin L), the capacitor C1 is charged through the diodes VD2 and VD4, and with a positive half-wave, the thyristor VS1 opens through the diode VD1 and discharges the capacitor C1 to a high-voltage transformer that forms an ignition spark. Diode VD3 serves to ensure the flow of current through the control electrode of the thyristor with a positive half-wave. The process is repeated at a frequency of 50 Hz and a powerful sheaf of sparks is formed on the ignition electrodes, instantly igniting the gas.

The circuit works as follows: with a positive half-wave of the mains voltage (pin L), the capacitor C1 is charged through the diodes VD2 and VD3, and with a negative half-wave through the diode VD1, the thyristor cathode VS1 is connected to the “negative” half-wave, and through the resistor R3, the thyristor control electrode is supplied control current. The thyristor opens and discharges capacitor C1 to a high-voltage transformer, which forms an ignition spark. The process is repeated at a frequency of 50 Hz and a powerful sheaf of sparks is formed on the ignition electrodes, instantly igniting the gas.

Before playing with sparks, you should know that high voltage is life-threatening, and in addition, each spark is a source of the entire range of radiation, including radioactive ones.
Most modern gas appliances use an electronic device to ignite the gas, here are a few from stoves

I became interested in these devices in order to make a home-made lighter based on them or according to such a scheme, due to the lack of normal electric stove lighters on sale.
It turned out that this is not such a complicated device as it seems at first glance.It is enough to apply 220V to the terminals signed with the letters “L” and “N” and high-voltage pulses will appear on the coil terminals, approximately 10 kV from each coil. In order not to damage the device, it is necessary to put jumpers between the leads of the coils so that the total clearance between the leads of each coil is no more than 10 mm. Like on a picture.

From such a device, you can make a separate lighter powered by the mains. It is not worth embedding it in the stove, since the refinement and modernization of gas appliances is not a rewarding and very dangerous business.

Here is a tentative diagram of the electric ignition.

I assembled it on a triac VT138 R1=100R 2w, R2=22k 0.25w, R3=1k 0.125w, C=3mf, on a ring ferrite (8 turns primary 50 turns secondary). She gave out sparks with a frequency of about 50 Hz, which could not penetrate 1 mm of air. It is necessary to wind the transformer on a rod core and on a special frame, or buy a ready-made device. And so, with a decrease in the turns of the primary, the strength of the spark weakened, and then, with two turns, the triac burned out.
————
I found the circuit for switching on the tor220-227 microcircuit, it is very similar to the ignition circuit

here the field effect transistor works on the primary, but for some reason it is connected in series. When using a microcircuit, 300V pulses are supplied to the primary, if two secondary windings are wound, one for feedback, the other boost, the output of which can be connected to a multiplier, the output of which sparks.

It seems there should be a lighter circuit more reliable and simpler. Who knows tell me.

On many models of gas stoves, designers install automatic ignition, which is turned on with gas supply or from a separate button. This function is very convenient: you do not need to come into contact with an open flame in order to light the burner. If you suddenly find that the auto-ignition on the gas stove does not work, do not rush to call the service: it is quite possible to repair this malfunction yourself.

Specialists in gas stoves, based on the statistics collected, compiled an approximate register of common failures.

1. When pressing the burner control knob or a special separate button, electric ignition does not occur.
2. The automation of the product in the gas stove works constantly, clicks are heard, but no spark - gas does not ignite.
3. After releasing the button or knob, the system does not turn off.
4. The device continues to work constantly, even when the button is not pressed.
5. Knocks out the machine protection in the housing panel at startup.
6. The circuit of the piezo ignition or electric ignition of the stove is closed.

Electric ignition can only be used on gas stoves. Its main function is to set fire to the blue fuel at the moment of its exit from the splitter of the burner installed on the gas stove. He happens automatic and mechanical type. In the first option, special piezoelectric elements ignite the gas-air mixture when the switch on the control panel is turned, and in the second case, the user must press a special button. The spark ignites the gas and you can start cooking. The automatic gas ignition device is the most capricious and unreliable device from the entire arsenal, which is equipped with a modern gas stove.

Very important! Never try to turn on the system if the burners are removed - a breakdown on the body is guaranteed.

All in all, this system looks like this:

• the user presses the button, thereby he applies voltage to the capacitor, which begins to charge;
• the level on the thyristor gradually increases, when it reaches the set threshold, the capacitor is discharged;
• a voltage arises at the output of the entire system, which activates a special device - a spark gap;
• the spark ignites the gas.

The whole system works much faster than we talk about it.The spark is supplied to the burner that is currently on (in older models, it was supplied to all devices, but the one where gas access was opened was lit). The start buttons are located below the controls. Electric ignition powered from the network with alternating current of 220 volts and is vulnerable to power surges, which occur quite often. After a power surge, it can constantly click, which indicates its breakdown.

The system will only work if a separate cable plug is connected to the home electrical network, which many users forget about and call the service with complaints.

Why does the electric ignition of the gas stove not work? There are several reasons for a malfunction in this device.

1. There is no spark on the electrodes.
2. Moisture or grease has entered the inside of the system or the surface of the spark plug.
3. A crack has appeared or the insulation of the ceramic candle has burst.
4. The transformer burned out - the spark generation unit.
5. The contacts of the power button are oxidized or soot has formed on them as a result of a short circuit.

Some malfunctions may occur after wet cleaning of the hob, when moisture enters the inside of the stove. To eliminate them, it is enough to do prevention: cleaning contacts, drying candles - almost the same activities are done by motorists.

If only one burner does not ignite, then the cause may be damage to the high-voltage wire to the ignition electrode, the ignition device itself, or a malfunction of the channel of the entire unit.

When you have inspected, found out the cause and diagnosed the problem, you can proceed to self-repair the gas stove. It is carried out in the same way for all models. The famous Italian brand Ariston or the Belarusian stove Hephaestus, which is in great demand among Russians - there is no difference, the ignition systems are almost identical, with the exception of purely individual nuances.

Refresh your knowledge by reading the product manual before starting work. Knowledge of the principle of operation and the device of a gas stove is necessary for its successful repair.

1. We set fire to a faulty burner using a third-party source of open fire, matches or a special lighter - the flame should be even and distributed around the entire circumference of the divider. Flame yellow means incorrect concentration of gas and air: it is necessary to clean the nozzle or replace it. It is possible that the divider holes are clogged or moisture has got there. It is necessary to do preventive maintenance, blow through all the holes, remove the body of the burner and inspect it.
2. All electrodes and switches are connected in parallel. Each electrode is powered by a single ignition unit, but they are turned on from different buttons. To make sure that only this button does not work, and the control unit is normal, you need to turn on the next burner. If gas ignition occurs - repair buttonand everything else in the system is working properly.
3. If the ignition device crackles constantly, then it is necessary check contacts - they could stick from the ingress of fat or carbon deposits formed as a result of oxidation. Before repair, do not forget to unplug the stove, then carefully dismantle it, clean the contacts or dry them with a hair dryer. Following the safety instructions will protect you from injury.

Most of the breakdowns that led to failure can be fixed on your own - they are not dangerous for the user, but it must be remembered that gas stoves are potentially dangerous products, so even preventive work must be done carefully.

Sometimes a breakdown of the ignition button leads to the fact that the repair will not help - a complete replacement is necessary. In this case, it is better to go to special stores and purchase a similar option.

In this topic, you will get acquainted with the electric ignition device for gas stoves, with their electrical circuits and how the electric ignition is diagnosed, in case of its malfunction.

The gas stove electric ignition unit consists of the following elements:

• diode;
• resistor;
• capacitor;
• thyristor;
• triac;
• transformer;
• the closing contact of the push-button post switch;
• electric spark plug.

The primary winding of the transformer (electric ignition) consists of two half-windings Fig.1. At the ends of these half-windings, the magnetomotive forces will be different, that is, the control electrode will receive alternately along the cathode of the thyristor VS1 - a pulse of positive and negative polarity. At the moment when a pulse of positive polarity is applied to the control electrode of the thyristor, the thyristor opens. The current at the same time, - the throw will increase to the nominal value.

The secondary winding of the transformer, consisting of two windings of parallel excitation, will supply electric ignition plugs

phase current. When the electric ignition is turned on, the phase intermittent current in the form of a spark will pierce, according to the law of physics, onto the body of the gas burner.

The second scheme of Fig. 2 in its essence, in comparison with the first scheme, does not change anything. In the circuit with the primary winding of the transformer, a triac VS1 is included with an anode control. In the open state, the current is passed in both directions, the anode control is also carried out using current pulses.

Diagnostics of household appliances, namely electric ignition, is carried out in a passive way without connecting to an external source. To check a resistor, for example, having a resistance of 510 Om, the “multimeter” device is set to the resistance measurement position, in the range from 200 Om to 2 k Om, that is, the digital value - 510 must be included in the set measurement range.

It should be remembered that in addition to its resistance, each resistor in the circuits of Fig. 1, Fig. 2 is rated for its rated power.

When replacing a capacitor, not only its capacitance is taken into account, but also the permissible voltage value set on it. For example, a capacitor has its own capacitance - 4 microfarads, the permissible nominal voltage value for the capacitor is - 400 V, - therefore, two values ​​\u200b\u200bmust be taken into account:

The thyristor is checked for its conductivity, while the device is set to the resistance measurement position, while the resistance value is checked between:

• control electrode and anode;
• anode and cathode;
• cathode and anode
• anode and control electrode.

The primary and secondary windings of the transformer are tested for resistance, while the device is set to the position of the smallest resistance measurement.

In gas stoves (without electric ignition), as you know, it is convenient to use piezo ignition.

The piezo ignition of a gas stove consists of two components:

• drive element;
• piezogenerator.

Piezo ignition works on the same principle as an ordinary piezo lighter.

That's all for now. Follow the rubric.

Good afternoon.
BOSCH hob. The electric ignition sparked on one burner - it works without interruption. I turned off the electricity, cleaned it, turned it on - the second burner sparkled - I looked at it before that. can you fix it on your own?

Hello Igor. You need to check in the electric ignition circuit - the push-button switch, that is, the switch contacts, as I believe, are constantly in the closed position. Switch contacts are subjected to:
heating under the influence of current;
oxidation;
burning.
If the switch is made in a stamping version, then of course it cannot be repaired and, accordingly, you need to select the same switch.

On one of the burners, the discharge does not seem to pass to the end, that is, you can feel it, but one burner does not light up, if you change the contacts on the block, everything is fine, does it make sense to clean the block itself or is it easier to buy a new one?

Hello Dmitry. The wire from the candle is inserted into the "socket" of the electric ignition unit. That is, here is the usual connection (connector-socket). The contacts must be cleaned well with a cotton swab moistened with any alcohol (for an electric ignition unit). Also, you need to inspect and, if necessary, clean the candles and their contact connections.
Victor.

The Whirlpool gas hob, when connected to the mains, the spark hits all the burners at the same time and does not stop until you disconnect from the mains, please tell me what could be the reason

Hello. I believe that this failure is a malfunction of the electric ignition switch.

Hello! I have an Electrolux hob and the same problem, I took it apart, checked everything seems to be clean, washed the buttons with alcohol and anti-grease, dried it, it didn’t help. Tell me how to check the operability of the bf95046-n00 electric ignition unit itself, everything is flooded with plastic, only contacts come out! It costs 1500 re in the service, before giving that kind of money for it, I want to make sure that it really grunted! Thank you.

Hello. Try to clean: contact connections of wires with electric ignition, contact connections of wires with electric ignition candles, contact connections of wires with electric ignition buttons. Also, you need to check the buttons themselves. The electric ignition button is checked with an indicator screwdriver, that is, you need to check the button contacts for inclusion. When you turn on the electric ignition from the candle, a spark breaks through the burner, respectively, you need to check the tips of the candles (if there is oxidation, the tips need to be cleaned). Check the electrical outlet to which the electric ignition is connected, check the electrical cord with a plug, each wire with candles. In general, everything needs to be carefully checked. Maybe the cause of the malfunction is not in the electric ignition itself, but in the malfunction of the button and so on. You may need to solder the wire from the candles.
If you have any questions for me, let me know.

Hello Viktor! So the situation is this. With the electrical ignition elements assembled and connected to the network, the spark breaks through all the candles and clicks constantly. When you turn off the block of electric ignition buttons, there are 4 of them sitting in parallel on 2 wires, a spark does not occur. I conclude: the block itself is working normally, and the block of buttons for turning on the spark is short. When it rings, its tester shows a short circuit. I disassembled and washed all the buttons with alcohol, cleaned the contacts, it still shorts ... I put it on the battery to dry, I'm waiting ...

Hello Sergey. Now you need to clarify the cause of the short circuit. It may be necessary to use a dielectric material - small pieces of PVC cambric of the appropriate diameter (that is, pieces of cambric are put on the terminals of the contacts to prevent short circuits). The buttons should probably not be washed with alcohol, condensation may form, followed by oxidation of the contacts. However, not everything is so bad - you yourself performed the diagnostics and found out that the electric ignition is in good condition.

In general, I report! The electric ignition unit turned out to be intact. It was all about one or two (did not specify) of the 4 ignition buttons. Determined by elimination. I took turns shooting and calling for a short circuit. As a result, both removed buttons were washed, dried and connected to a new place on the wires. Shorty is gone, everything worked! In the service, they asked for 1500 rubles for the ignition unit. for 4 buttons in the collection 1400 rubles. Master's call 500 rub. well, probably the installation of 500 rubles, for less they strain into scrap. As a result, he remained with the money and with a working ignition. Thanks a lot to Victor for your attention and help. Good luck everyone

I am pleased Sergey that everything worked out for you.

Hello Victor. The situation is this. When installing a new stove Hephaestus 5100-03, we checked the electric ignition, everything worked. A few days later we decided to use the oven and it turned out that the electric ignition (no spark) of the oven and grill was not working. At the same time, there is a spark on all burners and the gas is ignited normally.

Hello Sergey. I need to clarify whether the gas stove (Hephaestus 5100-03) has an electronic oven timer or not? If with an electronic timer, does the display show the time (current time and cooking time)?

Hello Victor. The timer is electronic, but it does not automatically turn off the oven. It only beeps.

Hello Sergey. I think that you yourself should not do anything (for repairs). The gas stove is new and the organization that deals with warranty repairs is obliged to fix this malfunction free of charge.
If the electronic timer of the oven is working, then the cause of the malfunction should be sought in the contact connections of the wires:
with electronic timer module,
with electric ignition candles (oven and grill).

Good day!
The problem is the following: There is an electrolux hob with electric ignition. One fine day, a spark began to beat non-stop on the burners. Turning off the power and ringing the buttons, I concluded that the short circuit was on one of the buttons. Dismantled, eliminated the circuit, fixed the buttons, everything seems to work. But after connecting, there was a “BOOM!” and knocked out the guns. The left contact on the electric ignition block with the inscription "on the buttons" melted. Perhaps due to the fact that I mixed up zero and phase.
I concluded that it was necessary to replace the electric ignition unit (when you connect the standard electric ignition unit and close the contacts “to the buttons” with a screwdriver, nothing happens). But such blocks are not available anywhere. There are only universal blocks (white). 220 comes to them already from the buttons, and not like on the standard one.
Question - how do I prikolhozit universal block? Can I just embed an existing block of buttons with a thin wire cross section into a circuit, for example, into a phase?
I am attaching an example picture.

Hello. The electric ignition unit must match the model of the Electrolux gas stove. Such information should be indicated in the instruction manual for the gas stove. Resolve your question simply - call a specialist to connect the electric ignition.

Hello, I removed the top cover from the gas hob, I had to get the spring from the handle, it failed when I was washing the stove. Put the cover back in place. Electric ignition stopped working, tell me how to fix it yourself

Hello. You need to contact a specialist (for repairing gas stoves), as this missing part (spring) can subsequently create a gas leak.

When you turn on the burner from a spark, it burns, but as soon as you remove your hand, it immediately goes out.

Hello. So this breakdown refers to a malfunction of the mechanism - the gas switch. To fix the problem, you need to call a specialist in the repair of gas stoves.

Hello. Plate Hephaestus 5100-02 ooo9. The spark has disappeared in the candle of the lower burner of the oven (there is a spark on all other burners). He removed the hob, swapped the stamps of the upper and lower burners of the oven in the electric ignition unit, a spark appeared on the lower burner and disappeared on the upper burner. Is this situation a failure of the electric ignition unit? If yes, can it be repaired.

Hello. I assume that this cause is a malfunction of the electric ignition. I recommend that you give the electric ignition for repair.

Victor, good afternoon! I have a NARDI stove, 2 burners stopped igniting. There are clicks, but they don't light up. no spark. Please tell me who should I contact to fix this problem? Do I need to call a specialist or is it possible to fix it on my own?

Hello, Tatyana. To inspect and troubleshoot a gas stove with electric ignition, you need the participation of a specialist, that is, you need to contact the organization that makes the appropriate repairs. It is risky to carry out repairs on your own, since the stove is gas.

When you press the handle, the electric ignition goes to all the burners at the same time, but one burner does not ignite because there is no spark on it, if you substitute a screwdriver, a very weak spark jumps, tell me how you can fix it.

Hello. It is necessary to check the contact connection of the wire with the electric ignition candle and with the electric ignition itself.

Hello. There, in my opinion, soldering to the electrode ...

Cheap printed circuit boards that make up the electronic stuffing of household equipment cost $ 10 rubles. The consumer avoids do-it-yourself repair of budget gas stoves with electric ignition. A price that exceeds $30 involuntarily provokes the thought of saving money. You visit the forum of radio amateurs: you see ... Ready-made electrical circuits for ignition devices. Wind step-up transformers, look for capacitors, solder, smoke equipment at your own peril and risk.

In contrast to most household appliances, repairing gas stoves with electric ignition forces you to master the technique of replacing resistors. Frequent, constant process. Newcomers, challenging the expediency of the event, cause general indignation among members of the forum. They call the amateur with offensive phrases, condescendingly explain, inside the high-voltage unit:

1. High voltage transformer.
2. Capacitor.
3. Diode.
4. Resistor.

The electrical circuit is filled with compound on purpose, the burdock will not climb inside. You pick it up, saving your hard-earned $30. The self-taught person ignores the manufacturer's thoughts about protecting products against unauthorized access.

The gas stove electric ignition unit optionally contains control elements - thyristors, triacs. It takes a long time to explain the exact principle of operation of the components of electric ignition. It is worth noting: the behavior of semiconductor products resembles a key (faucet - plumbers are more accustomed to thinking). Semiconductor electronic elements are used to control the power line by means of a voltage with an amplitude of 5-12 volts.

The water valve analogy is complete. A person makes a symbolic effort, opening the tap, releasing the utter power of the pump. The scanty voltage of the control electrode reaches the operating point, the thyristor opens, starting the electric ignition circuit. There are two positions: open, closed. Digital microelectronics of pure water. Any processor is formed by semiconductor keys - miniature, indistinguishable by the human eye. The PC is considered a logical evolutionary continuation of electronic circuits.

A high-voltage transformer increases the voltage (a few kilovolts) of the output winding, the slot of the spark gaps of the burners is illuminated by an electric arc. Gas is supplied by the handle of the same name, starting the electric ignition circuit. There are other models of devices. Thanks to the spark, the gas ignites:

• by pressing the button, the cook charges the capacitor with a rectified voltage;
• capacitance begins to accumulate electrons;
• the voltage level of the control thyristor rises, when it reaches the threshold value, the capacitor is discharged, heating the primary winding of the transformer;
• the output of the electric ignition circuit generates a voltage that causes the arrester to operate;
• the spark ignites the gas.

The principle of operation of electric ignition is based on charging the capacitor through a rectifying diode to a certain level. Specific implementations of the schema vary. Be ashamed to study the textbook of an electrical engineer: repairing the electric ignition of a gas stove with your own hands is easier than a steamed turnip. Know a couple of rules, know how to solder.

The mentioned resistor of the electric ignition circuit is often 3.9 kOhm. The dissipation power is 0.5, less often 1 W.The size of the capacitance has long been known (according to the members of the forum) - a couple of fractions above 2 microfarads (the numbers go in jumps according to the series given by GOST, it will not be possible to find exactly 2 microfarads, except from the E24 series) with an operating voltage of 250 volts. The radio amateur will not notice the difficulties. There were times - TVS manually rewound!

The average person wants to know the sequence of actions. First, it is necessary to disconnect the electric ignition of the gas stove from the voltage source. In the second step, the electronic, high-voltage blocks are removed. The design comes with separate printed circuit boards, a single substrate. There are other options.

Start the inspection by evaluating the quality of the tracks, solder joints. The conductor layer, which looks like a silvery stripe, is covered with a layer of varnish. Made to protect the electric ignition circuit from external factors, primarily moisture. The varnish reliably covers the conductive layer. Do you have nail polish at home? It will fit 100%.

Nagar is cleaned with a zero sandpaper, degreased with alcohol, varnished on top. Delaminated, torn tracks of the electric ignition circuit are restored.

Example. The conductive layer is torn. Both edges are slightly cleaned with emery, tinned, connected with solder. Lacquer is applied over the cooled solder, alcohol is applied as needed. For wiping the printed circuit board, of course.

The burnt resistor is black. The value is listed above. It is not forbidden to put an element more powerful. Eyewitnesses unanimously assert: the further process of operation is going excellently. Let's give the plate circuit a resistor with a nominal value of 9 kOhm. It is better to take the dissipation power equal to more than the same parameter of the original element. 1W is fine.

The failure of the capacitor is visible from afar. Some (electrolytic) swell, a swollen keg is impossible to miss for an attentive master. Regarding the denominations, it is recommended to ask the members of the forum. Modern marking of resistors with multi-colored rings is more complicated than the prevailing alphanumeric inscription. The tolerance was expressed as a percentage.

Repairing the electric ignition of a gas stove can be a simple matter. If the transformer windings are burned out, you will have to buy a new one. Do you want to check the localization of the problem? At each output we find a pair that rings. Resistance (use a multimeter) is hundreds of ohms. There were “legs” hanging in the air: rather, a transformer installation problem. Rewinding a job is not easy. The expanses of the network will provide valuable information. A core of the form of the letter Sh is used. There are dozens of primary turns, the secondary winding will have to be taken seriously.

After examining the printed circuit boards of the gas stove, pay close attention to the state of the button. Control panel element that starts the spark gap ionization process. The contacts of the electric ignition button are powered by a centralized network voltage of 230 V. Brass contacts are easily melted by a welding arc in the event of a short circuit. It is recommended to clean the sites, check the operability of the switch with a multimeter (ringing).

Suitable product that can withstand the operating voltage. Electric ignition will not work worse. At times, installation is accompanied by technical difficulties. The button does not fit the installation dimensions of the housing. Finish with a file.

The main thing is to properly solder the cross-connect, the necessary spare parts are often sold separately.

Each burner is equipped with a candle, a combustion control device (thermocouple). The electric ignition of a gas stove is schematically a little different from an ordinary car. Do you want to check the serviceability of the gas stove electric ignition candles? Turn off the gas. Remove the reflectors, dividers of each burner (round things that form tongues of fire), look ... When you press the ignition, the products give a good spark. Broke 1 candle? The cause of the breakdown of the electric ignition of the gas stove was found.

The combustion control circuit is composed of a thermocouple (temperature sensor of any type).It happens that the electric ignition works 100%, the gas refuses to burn. It's more about this node. The command blocks the blue fuel supply path. A regularly beating spark of a gas stove is powerless to set fire to air devoid of a combustible mixture.

The electric ignition block is equipped with 4 or 6 outputs, the reason for the need for the specified number of contacts is hushed up in the literature. We believe that 1 pair is involved in the oven, grill. Current trends oblige the manufacturer to produce models a la Two in one. A gas stove with electric ignition of the oven is convenient: you will find models where the possibility is not implemented, and those where you will have to modify the copper core circuit. You need your husband's help.

We are ashamed to call electrical circuits for igniting a gas stove complex. Radio amateurs make it easier. The getinax board is etched, the necessary elements are soldered. The initial composition of the electric ignition of the gas stove provides ready-made transformer, the button discussed above.

An experienced engineer can usually improve on a given by the manufacturer. The Internet gives a curious scheme for the electric ignition of a gas stove, formed by a triac, strikingly simple.

The Zanussi gas stove with electric ignition will make you forget the look of a matchbox. So say the official representatives of the company. The business class segment is represented by Gorenje products (Slovenia). Despite the abundance of brands, an almost complete list belongs to the Electrolux concern (headquartered in Stockholm). The mentioned Zanussi belongs to the category.
