Why does a gas stove burn for a while and then turn off automatically?

It is possible that the battery is out of charge, so it can be ignited at first, but it burns for a while and then goes out, in which case you can try to replace it with a new battery. There is also the possibility that there is no gas.

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 equipment, 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.

However, if the flame still stalls after adding gas, it is necessary to consider that the thermocouple may be aging. It is also a tool for detecting gas, so there is no way to detect the gas, so the pulser cannot sense it, and it will not ignite.

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. Check whether the connection between the probe and the controller is intact, and if the plug connector is dropped, plug it back in.

Notes:

The extinguishing device of the gas stove will go out 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.

1. 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.

A thermocouple is a feedback device, and it is also described in detail above if the thermocouple has a product quality problem or is damaged.

Of course, it is not possible to light the fire normally, and when the fire is lit and extinguished, there is no doubt that everything is normal.

If such a thing happens, you can carefully check whether the thermocouple is damaged or the thermocouple you bought is of poor quality.

3. The battery capacity is not enough.

The ignition of the gas stove must rely on a rechargeable battery, and there is often a rechargeable battery at the bottom of the gas stove.

If the rechargeable battery has been used for a long time, you will find that the ignition is relatively weak, and there is not so much squeaking sound, which means that the rechargeable battery is out of power and must be replaced immediately.

4. The thermocouple is sluggish.

When the gas stove is often adhered to by the juice or vegetable juice, the thermocouple will be sluggish after a long time, and the ignition will not ignite or turn on and then extinguish.

5. Feedback needle connection.

When the feedback needle is touched, the feedback needle cannot push the appropriate data signal to the single pulse, so that the single pulse cannot open the gas circuit normally, and the gas stove cannot ignite.

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 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.

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.

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.

The flame-out protection device is to adjust whether to open the baffle at the connection between the gas valve and the pipeline by sensing the temperature of the flame by the induction needle, and the baffle is opened, and the gas passes through to the flame to burn normally.

When the flame-out protection device does not sense the flame (i.e. the wind handle or blow out), the baffle is not opened, so the gas cannot pass through, and the gas leakage cannot be caused to ensure safety.

Notes:Flame-out protection induction pin failure (skewed or line fault).

This situation needs to be repaired, please call the local service **.

First of all, it may be because the power of the gas stove is insufficient, only enough to turn on the stove, but not enough to keep the solenoid valve open, and it will turn off after a while, just replace the new battery. Secondly, it may be that the flame of the stove is unstable and the induction needle is not burned, you can check whether the air source ** is insufficient or the wind blows the flame to cause deviation.

Answer: Hello, there may be the following reasons: improper orientation of the incineration needle will cause the separation between the incineration needle and the fire cover of the gas stove to exceed the required interval, and the interval exceeding the standard will cause the gas stove to turn off automatically.

Solution: Control the distance between the incineration needle and the fire cover within the range of 4-6mm, and aim the fire hole when ignition.

2.Incineration needles are dirty. If the gas stove is used for a long time, then the incineration needle is easily stained by oil, and the incineration needle is too dirty, which will cause the gas stove to turn off automatically.

Solution: Clean the incineration needle and use it again after cleaning.

3.Insufficient gas or air pressure can also cause the gas stove to turn off naturally.

Solution: Replenish gas or air pressure.

4.Once the electronic lighter is damaged, it cannot work normally, and the gas stove is naturally extinguished;

Solution: Replace it with a new electronic lighter.

5.If the gas contains miscellaneous gas, it will cause the gas to be impure, so that it cannot support the normal operation of the gas stove

Solution: Replace it with a new gas with higher purity.

6.If the sensor needle is broken, the gas will be extinguished automatically;

Solution: Ask a professional to replace the sensor needle.
