What will happen if the gas stove turns off automatically?

1. Poor circuit contact, the longer the use time, the greater the possibility of poor contact;

2. Check whether there is gas;

3. The pipeline is blocked, usually you can smell the smell of gas, and the gas stove can't catch fire, it is likely to be gas blockage;

4. Over-pressure protection, some gas stoves will have the function of over-pressure protection, and the pressure reducing valve needs to be replaced;

There are many reasons for automatic extinguishing of gas stoves, and the most direct reason may be that there is no gas, if it is not the cause of gas, how to troubleshoot it? Next, let's take a look at the causes and solutions of gas stove failures.

1. Poor circuit contact, due to the longer the use time, the greater the possibility of poor contact, check whether the positive and negative poles of the battery box are rusty, whether the line is in poor contact, if there is a need to remove the rust, and accurately connect the line.

2. Check whether the battery is charged. This is also the direct cause of the flameout, after checking whether there is gas, if there is a problem, it is judged whether it is a battery problem, and when there is no power, you need to replace the battery with a new one.

3. Pipeline blockage, check whether the pipeline is blocked, once blocked, you need to check the gas outlet valve, usually you can smell the gas stove and the gas stove is not on fire is likely to be gas blockage, you need to dredge it in time to use it normally.

4. Overvoltage protection. Some gas stoves will have the function of overpressure protection, and they will not start after overpressure, and the pressure reducing valve needs to be replaced.

5. The position of the ignition needle is deviated. The distance between the ignition needle and the fire cover has certain requirements, if the distance deviates too much, it will cause the gas stove to not ignite, the distance between the two is controlled at 4 to 6 mm is the most appropriate, and the fire hole needs to be aligned.

1. After the gas stove is turned on, the flame must be burned to the thermocouple, if the fire hole is blocked, it is difficult to achieve this condition, so at this time, the gas stove may automatically turn off. 2. When in use, the gas is originally burned normally, because the thermocouple has been used for a long time and has been aged, and the signal provided to the pulser is not strong, so the pulser will mistakenly think that there is no flame and automatically close the solenoid valve. 3. Abnormalities in the feedback loop, such as virtual connection, lapping, and aging, will cause the signal to weaken and affect the pulser, which will cause the gas stove to go out.

4. If the battery is not replaced regularly, the battery power is insufficient, and the gas stove will automatically turn off. 5. If the damper is in front of the stove, and the back of the stove is biased to both ends of the stove in the middle of the stove, which is used to adjust the outer ring fire and the inner ring fire respectively, try to rotate back and forth to control the air intake, and you can see that there is no red fire. If the air blows the flame away from the ion sensing needle, the gas stove will automatically turn off because the valve is closed.

This situation is still relatively common, and there are many reasons for this situation, the common ones are:

1. Air pressure is unstableThe gas stove is on, but the flame is too weak, so weak that it can't reach the stove head, so that the air pressure of the gas stove will be very low, and the natural gas stove will not be able to burn the fire as usual, and will go out.

2. The gas thermocouple is broken:This situation occurs when the flame of the gas stove is normal, the thermocouple is old or damaged, and it cannot provide the signal of strength to the pulser as usual, and the pulse of the gas stove will automatically close the solenoid valve, and the flame will be turned off naturally.

3. Other situations:There are many other reasons, such as a clogged feedback loop in the gas stove, and the feedback needle is so attached that the signal cannot reach the pulser. Of course, the gas stove will also turn off when the battery is insufficient.

There are two situations in which the gas is sufficient and automatically extinguishes the fire in the combustion of the gas stove: 1If the air intake is insufficient, the gas cannot be burned and the gas will automatically turn off. 2.The extinguishing induction activates to close the gas stove intake valve and extinguish the flame.

The cause of insufficient air intake: the gas stove is embedded in the cabinet, and the cabinet does not have ventilation holes. The way to check is to open the cabinet door under the stove and use the stove to see if the fire is turned off.

Or take the stove to the countertop and not embed it in the cabinet to ensure that the gas stove is exposed to air in all directions.

Excluding the situation that the gas stove is extinguished due to insufficient air intake, that is, the extinguishing device starts and closes the gas stove intake valve, which causes the gas stove to be extinguished. There are several possible reasons for this:

The loose thread buckle of the valve body of the gas stove causes the pressing twist to be not in place. This usually results in a successful activation of the rotary twist and the extinguishing of the stove immediately or within a few seconds after letting go.

The battery of the ion-extinguished cooktop is low and the valve closes, cutting off the gas supply. There are two No. 1 batteries for the ion-extinguished stove, and the batteries need to be replaced once every 2-3 months. A stove with two No. 1 batteries that burns out during combustion is most likely the battery needs to be replaced.

The flame in the center of the gas stove is detached. Observe whether the flame in the center of the gas stove burns with some air outlets and no flame burning. This is usually the case when the gas pressure is too high, or the damper is too large, causing the center to ignite.

If the flame is separated from the flame, it is precisely a few vents that the induction is aimed at. It is to cause the cooker to conclude that the gas stove is extinguished and close the gas cooker intake valve and turn off the flame.

The gas stove backfire causes the flame to rise and shrink erratically, and the extinguishing line concludes that the stove is extinguished and closes the air intake valve. The reason is that the gas pressure is too low or the damper is too small. Factors such as incorrect placement of the fire cover cause the gas stove to be less than the gas velocity.

The flame retracts back to burn inside the cooktop. It is necessary to increase the air pressure or damper. Check that the fire cover is placed in the correct position.

Check the relationship between the flame sensor needle and the flame position. Generally, it is necessary to ensure that the tip of the flame sensing needle is in the central flame. If the position is not good, it will lead to insufficient sensitivity of the sensor needle and misjudgment.

The reasons for the flameout in the combustion of the gas stove are roughly the above points. As long as the stove can burn, the basic big problem may be gone. It's just a small situation. Check the above points to solve the problem.

To ensure the continuous combustion, the gas stove must ensure that the feedback circuit (of course, the weak current) is unblocked

When the flame is normal, the feedback loop will provide a continuous gas supply signal to the pulser, otherwise, the pulse will close the solenoid valve (the automatic control element in the gas stove is the second valve in the gas circuit, and the first valve is a manually controlled plug valve, which is in the assembly).

There are two conditions for unimpeded feedback:

First, the flame must burn to the feedback needle (or thermocouple), if the corresponding fire hole is blocked by carbon deposits, or the fire hole and the feedback needle are not aligned, the flame can not be directly burned to the feedback needle, the pulser will think that the flame is extinguished, and immediately shut down the gas source. During maintenance, the flameout of the stove that has been used for a period of time mostly belongs to this situation.

In another case, if the flame is normal, but the thermocouple that acts as a feedback is aging (or the original quality is not good), the signal provided to the pulser is not strong enough, and the pulser will also close the solenoid valve.

The third situation is that the feedback loop is not smooth, such as virtual connection, aging or feedback needle hitting, and the signal cannot be reached.

The last possibility is that the battery is running low.

I am a public health professional, and in recent years I have focused on kitchen appliance hygiene, because of the needs of scientific research, my maintenance theory of water.

Case: Ms. Liu, a citizen, is cooking at home, making soup on the stove, at this time, the TV show is playing her favorite TV series, Ms. Liu used to watch an episode, and was waiting to watch the next episode, at this time, the flame on the gas stove suddenly went out without knowing what happened, and the gas slowly spread out from the stove head, when Ms. Liu went to the kitchen to see the soup on the gas stove, she saw that the flame of the gas stove was extinguished and re-ignited it, at the moment when Ms. Liu lit the stove head, The gas that had leaked before was ignited and ignited, causing a deflagration that burned Ms. Liu's arm.

After the investigation, the reason was that the stove exceeded its service life and the flame-out protection of the stove failed, which caused the gas stove to automatically turn off and cause gas leakage and deflagration.

Through the above case, we must know that even if the stove has a flame-out protection device, it cannot leave people at will when using gas, and someone must guard it when cooking. The gas stove at home must be replaced in time beyond the service life to prevent the failure of the internal device of the stove and the danger of occurring.

In addition, for the occasional or frequent automatic flameout of the stove in the use of the home, it is necessary to check whether it is because of the long use of the flame out protection induction needle carbon deposit, with a copper wire brush to re-test the use of observation, if the problem still exists, be sure to contact the stove after-sales personnel in time to investigate, to prevent the use of unsafe gas stoves.

For a long time, the safe use of household appliances has always been a problem that everyone is very concerned about, but as a frequent gas in daily life, it is indeed difficult to guarantee that the situation of automatic flame-out will never happen.

Gas stove repair inspection steps.

1.Preliminary inspection of the cause of automatic extinguishing of gas stove.

When encountering the situation that the gas stove automatically turns off, first check whether the connecting hose is flattened or bent, and if it is not flattened or bent; Secondly, check whether the combustion flame is too weak, if it does not reach the furnace head, the gas pressure is too low, the user who uses the liquefied gas stove suggests that it replace the new pressure reducing valve, and the coal gas and natural gas can be consulted and reported to the gas supply company.

2.Advanced investigation of the reasons for the automatic extinguishing of the gas stove.

First of all, you can replace the battery, and then see if the flame in the middle can burn the probe on the broken side, because only by burning the probe can the fire be fixed. Secondly, to ensure the continuous combustion, the gas stove must ensure the smooth flow of the feedback circuit, the feedback mechanism of the gas stove is mostly set in the place where the flame can be burned directly, when the flame is normal, the feedback loop will provide a continuous gas supply signal to the pulser, otherwise, the pulser will close the solenoid valve.

3.Special attention is paid to the reason for the automatic shutdown of the gas stove.

Now, many gas stoves are equipped with automatic protection devices, usually this kind of gas stove is installed with a solenoid valve at the inlet pipe, when ignition, the mechanical mechanism will link the solenoid valve switch, so that the solenoid valve can be electrified to work, so that the gas can be provided normally, when used, after the gas stove is extinguished due to the wind, overflowing pot, etc., the ionization probe next to the gas stove burning head can not "pick up" the ionization signal of the flame, so the protection circuit is started, and the gas solenoid valve is released to close the gas.

Gas stove maintenance tips.

1. The oil stains generated by the gas stove after being used for a period of time not only affect hygiene but also easily cause gas stove blockage, so the gas stove needs to be cleaned regularly.

2. Find professionals to repair and regularly check the air tightness of the stove and air supply system with foaming agent.

3. Clean the tile of the stove. Use discarded candle heads, the surface of the candle is smooth, even if there is oil stained on it, as long as the ordinary dish soap is mixed with water and gently wipe it, gently apply the seams of each tile, first paint in the direction of the seam, and then apply it horizontally, be sure to make the thickness of the candle equal to the thickness of the tile.

4. Deep cleansing method for the stove.

Mix two spoonfuls of white vinegar with 200ml of warm water, then use a sponge and an eco-friendly loofah to dip this "hot vinegar water" to clean the stainless steel cooktop to make it shine like new.

Have you remembered what is going on with the gas stove turned off and some methods of repair and maintenance introduced above? For the gas stove, we should pay more attention to its maintenance, so that we will use it smoothly and make delicious meals!

Gas stove is also called stove, according to the gas source, gas stove is mainly divided into liquefied gas stove, gas stove, natural gas stove. According to the eye of the stove, it is divided into single foci, double foci and multi-eye foci. However, the use of gas stoves is not smooth sailing, and there will often be failures, some gas stoves will automatically turn off, and even some gas stoves will not catch fire, which requires owners to know some basic gas stove maintenance skills.

What should I do if the gas stove can't catch fire, what is the reason why the gas stove automatically turns off, and what are the maintenance skills of the gas stove? Next, I will explain them one by one to the owners and friends. First of all, what should I do if the gas stove doesn't catch fire?

If the gas stove does not catch fire during the use of the gas stove, it should be checked according to the following procedures: the gas stove does not catch fire to solve the problem 1, first check whether the gas source switch is open; 2. Check whether the connecting hose is flattened or bent, if it is not flattened or bent, then, finally, pick up the pot rack and see if there is a fire at the ignition nozzle. If the gas stove does not catch fire, if it does not ignite, see if the discharge needle is discharged; If the discharge needle does not discharge, it means that the discharge needle is faulty and the discharge needle should be replaced; If the discharge needle is discharged, it means that the valve body is faulty and the valve body should be replaced.

If the gas stove can not ignite, it means that the ignition is high, and the user should be instructed to gently press the igniter down a few times, and then put the pot holder; If the flame is too weak to reach the furnace head, the gas pressure is too low, and the user of the liquefied gas stove recommends that it replace the pressure reducing valve with a new one, and the coal gas and natural gas should be reported to the gas supply company. If the flame can reach the fire cover, but it just does not catch fire, it means that the valve body is blocked, and the user is instructed to dredge the nozzle with a thin wire.
