The gas stove will automatically turn off when it burns, why does the gas stove turn off automatical

The gas stove will automatically turn off after a while. The flame-out protection device is a safety protection device that automatically closes the gas valve when the gas stove encounters an accidental flame-out, if the fire is blown out by the wind or the fire is extinguished by cooking porridge overflowing, the flame-out protection device will close the gas valve to prevent a large amount of gas from leaking into the room to cause poisoning or fire accidents. The situation where the gas stove automatically goes out can be caused by the following willingness:

1. Observe the color of the flame, if there is any abnormality, such as the flame is yellow, you need to adjust the damper. 2. Check the ignition battery voltage. When the voltage of the embedded stove battery is too low, it will turn off the flame protectively.

Just change the battery. 3. Check whether the temperature on the combustion plate is heated with the flame, even if it is a small fire. 4. Whether the top cover of the burner is misplaced, not in place, and the cover is wrong 5. The flame-out protection automatically closes the gas path, so the flame is extinguished.

What causes a gas stove to turn off after 10 seconds of ignition? Common faults and troubleshooting methods for gas stove flameout protection: pulse igniter has no battery or insufficient battery voltage Install the battery or replace the battery.

The air source switch is not turned on or the air pressure is insufficient: Turn on the air source switch or replace the cylinder with a new one, or ask the gas company if the gas is off. Ignition electrode, induction electrode distance is improper or polluted Adjust the ignition electrode to a reasonable distance and clean the electrode. The air pressure is too high, causing the air flow speed to be too fast, and the impact spark Adjust the opening of the air source switch appropriately to reduce the air pressure.

The ignition nozzle is too large, and the nozzle is too large to cause too much airflow, and the impact of the electric spark Replace the nozzle. The head is damaged, resulting in the replacement of the head by ignition too close to the damaged part. The ignition output cable is not firmly connected to the porcelain head, plug it firmly and use 502 glue.

or other glue firmly. The output cable is damaged, resulting in ultra-close ignition Replace the cable or wrap the damaged area with insulating tape. The internal impact block of the switch total range is worn or cracked Replace the new impact block, pay attention to the correct installation position. Pulse ignition total range micro switch.

Poor contact Repair or replace the micro switch. There are cobwebs in front of the ignition nozzle or in the ignition support.

Clear the cobwebs. Hose pressure twist or clog Remove the blockage and correct or replace the hose.

There are two possibilities, 1. One is that the ignition time is too short, the thermocouple is not heated, the voltage cannot be generated, and the solenoid valve cannot be kept on, resulting in gas cut-off, 2. There is also a possibility that the battery is not enough or the battery is in poor contact, resulting in the solenoid valve being unable to engage and the solenoid valve being closed. It's going to go out. The picture below shows two different solenoid valves:

1. What is the reason why the gas stove is extinguished after a while?

1. It is possible that the battery is out of power, so it can be ignited at first, but it burns for a while and then goes out, in this case, you can try to replace a new battery. If the battery is replaced, there is still a problem of stalling, it is possible that the flame did not burn the feedback needle. The feedback needle is a safety protection device, which is mainly used to detect whether there is a fire.

If the ignition position does not reach the feedback needle, the gas will be automatically cut off, and there is no way to maintain normal combustion, and there is a problem that the fire can be ignited at the beginning and extinguished later.

2. Of course, there is also a possibility that there is no gas, which will also lead to the problem of flameout, but if the flameout still occurs after adding gas, it is necessary to consider that the thermocouple is aging. It is also a tool for detecting gas, so there is no way to detect the gas, so the pulse cannot be sensed, and it will not ignite.

Second, why do you turn off the fire when you let go of the gas stove?

1. The gas stove should be operated by the knob, but if you hold the button, you can light it normally, but it will be extinguished as soon as it is loosened. It is possible that the operation is incorrect, because many products nowadays are equipped with flame-out protection devices, which need to be held for more than 5 seconds when ignition. Wait until the sensor needle has played its role before you can let go.

2. It may be that the flame separator is not placed correctly, and there is a buckle between the flame separator and the flame separator seat, which must be aligned with the buckle and cannot be displaced, otherwise it will be extinguished once the hand is released, and it will also lead to combustion deformation. After a long time, this device was scrapped. If this is the case, a new flame splitter needs to be replaced, and it must be well placed.

Fault phenomenon: extinguished after a while of ignition.

Cause of failure: Flame-out protection induction pin failure.

The gas stove will be extinguished after a whileFault analysis:

1. Flame-out protection induction needle failure. The sensor needle is skewed or the contact is bad. This situation needs to be solved by a maintenance worker.

2. Due to the usual simmering soup overflowing pot, the soup adheres to the flame-out protection needle, resulting in sluggish induction.

Solution: At this time, the flame-out protection device should be cleaned.

3. The fire cover is not properly placed. The fire cover (ring-shaped, surrounded by a black copper object with fire holes) is not placed in place (except for the same size hole around the fire cover, there are two small holes next to each other, these two small holes should be facing the ignition needle), if the fire cover is not properly covered, the gas conduction is slow, and the ignition is slow.

Workaround: Reinstall the fire cover.

4. The solenoid valve is not opened, and the air source does not flow to the fire hole.

Solution: Adjust the height of the thermocouple to let the flame burn it, let it generate voltage due to the temperature difference to open the solenoid valve, and let the air source flow through the fire hole.

5. Check whether the thermocouple and the solenoid valve have formed a circuit loop, if there is no loop, the solenoid valve cannot be opened.

Solution: You can open it with a screwdriver, but if you don't have basic knowledge of the circuit, it is recommended to find an after-sales service.

Answer: The gas stove has automatic gas cut-off protection, and most of this situation is one reason, that is, the protection probe detects that the fire has been extinguished, so it automatically cuts off the gas. You need to manually disassemble the stove, unscrew the ignition needle, and pull out a part of it. 1. Check whether the probe on the stove can be burned by the burning flame, if not, it will cause gas outage to extinguish the fire.

At this time, there are generally two situations, one is that the stove is dirty, and the flame against the probe does not burn to the probe, but the damper is not properly adjusted, so that there is no gas in the flame against the probe, try to adjust the damper, and know that the flame at the probe site can continue to burn the probe. 2. Check whether the connection between the probe and the controller is intact, and if the plug connector is dropped, plug it back in.

Hello question! Answer precautions: The gas stove extinguishing device will be extinguished if it is not heated to the temperature of the suction valve. Using the physical properties of metal, it belongs to temperature difference induction, and the flame-out protection action is controlled by temperature sensing.

When the temperature drops below a certain temperature, the gas supply is immediately cut off, which is an instant reaction, and the general extinguishing time is about 5 to 10 seconds.

The gas stove has automatic gas shut-off protection, which is mostly due to the fact that the protection probe detects that the fire has been extinguished, so it automatically cuts off the gas. You need to manually disassemble the stove, unscrew the ignition needle, and pull out a part of it. 1. Check whether the probe on the stove can be burned by the burning flame, if not, it will cause gas outage to extinguish the fire.

At this time, there are generally two situations, one is that the stove is dirty, and the flame against the probe does not burn to the probe, but the damper is not properly adjusted, so that there is no gas in the flame against the probe, try to adjust the damper, and know that the flame at the probe site can continue to burn the probe. 2.

01 Poor circuit contact.

If the gas stove is used for a long time, it is prone to poor contact, resulting in failure to ignite or automatic flameout.

In this regard, we can check whether the positive and negative poles of the battery box are rusty, and whether the wiring is not in good contact. If there is, remove the rust and connect the lines accurately.

02Check if the battery is charged.

The gas stove battery is dead, which is the direct cause of the flameout.

In this case, we need to check if there is gas on the gas stove. Yes, at all. then determine whether it is a problem with the battery; If the battery is out of charge, replace it with a new one.

03 Pipeline blockage.

Under normal circumstances, the gas stove pipe is blocked, which will also cause the gas stove to fail to ignite or turn off automatically.

For this, we need to check the outlet valve. Normally, if you can smell the gas, but the gas stove does not catch fire, it is likely that the gas is clogged. At this time, we only need to dredge it in time to use it normally.

04 Overvoltage protection.

Nowadays, many gas stove products have added overvoltage protection function in order to ensure safety. When this kind of gas stove is used, once it exceeds the standard pressure, it will not be started again, and it will naturally not ignite.

For this, we only need to replace a pressure reducing valve.

05 Ignition needle position deviation.

When the gas stove is used, there are certain requirements for the distance between the ignition needle and the fire cover. If the distance deviates too much, the gas stove will not catch fire.

If the gas stove burns for a while, it will automatically turn off. It should be the oil that blocked the hole. The landlord can use the wire to dredge the oil hole, and it can be used normally.

The gas stove automatically turns off, which can be solved by the following methods.

1. Replace the battery, and then see if the flame in the middle can burn the probe on the broken side, and the probe must be burned to fix the fire. When there is still a point, you can press and hold it for ten seconds, and when you loosen the switch, the probe is the heat induction, and it needs to be burned to fix the fire.

2. 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. However, there are several conditions that need to be met to solve the problem of automatic fire out of gas stoves. Feedback is smooth.

1. The flame must be burned to the feedback needle, if the corresponding fire hole is blocked by carbon deposit, 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 close the gas source. During maintenance, the flameout of the stove that has been used for a period of time mostly belongs to this situation. Feedback is smooth.

2. If the flame is normal, and the thermocouple that plays the feedback role is aging, and the signal strength provided to the pulser is not enough, the pulser will also close the solenoid valve. 3. The feedback loop is not smooth, such as virtual connection, aging or feedback needle tie, and the signal cannot be reached. There is also a situation where the gas stove automatically turns off may be that the battery is insufficient, which also needs to be paid attention to.

The fire hole is blocked or the feedback needle is crooked. Thermocouple, also known as feedback needle, is a kind of safety protector, the feedback needle is based on the temperature of the magnetic induction flame to open the gas valve and the partition at the junction of the pipeline, only the magnetic induction of all normal temperature, will be based on the natural gas, so that the gas stove can be ignited normally. 2. Thermocouple embrittlement.

1.Some people are more sloppy, such as the gas stove itself is not enough gas, or there is a recharge type gas meter, if it is not recharged in time, it will lead to insufficient gas volume, and the problem of gas outage will appear, so it will automatically turn off. Or because there is no battery, it will also lead to the problem of automatic flameout.

2.The second reason is that in the process of use, it may be good at the beginning, but the gas stove circuit is not smooth, which will lead to insufficient gas ** and the problem of flameout.

The gas stove will automatically turn off after a while, check whether the gas stove hole is unobstructed, whether there is water blockage, clean the gas hole, if it still can't be used normally, it means that it needs to be replaced.

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

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

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

Hello, dear, very happy to answer for you! Here's the answer, check out the Dry Rent God! Generally speaking, the gas stove will automatically turn off when it burns, which may be caused by the following reasons:

1.Poor flame diffusion: that is, the flame diffusion is poor, and it fails to dissipate in time, so the flame is extinguished; 2.

Insufficient gas volume: that is, due to insufficient gas volume, the flame is sucked by the air and extinguished; 3.Hot air blower malfunction:

That is, due to the failure of the hot air blower, the flame is blown out by the air wind; 4.Pressure valve failure: that is, due to the failure of the pressure valve, the flame does not have time to spread and goes out; 5.

Control switch failure: that is, due to the failure of the control switch, the flame cannot be controlled, resulting in flameout. In short, the flameout is caused by the cause of the fire or the system abnormality, and it is necessary to seek professional inspection and resolution.

The reason why the gas stove burns for a while and then turns off automaticallyThe gas stove burns for a while and then turns off automatically, which may be due to the flame-out protection on the right. There is a flame-out induction needle on the left and right sides of the gas stove, but there is only one solenoid valve to control the gas circuit, and one of the stoves is turned off, which will cut off the main gas circuit to prevent accidents.

Specific solutionsThe workarounds for this situation are:

1. Adjust the damper to the flame without de-ignition or from the flame, and ensure that the induction needle is burned by the flame;

2. Check whether the fire hole near the induction needle is blocked;

3. Check whether there is rust on the induction needle, and remove it lightly with steel wool balls and fine sandpaper;

4. Remove the fire cover, and polish the contact surface between the fire cover and the stove head with steel wool ball and fine sandpaper;
