What happens when a gas stove is lit for 20 seconds and turns off automatically?

Clogged fire hole or bent feedback pin: thermocouple.

Also known as feedback needle, it is a safety protection device. The feedback needle senses the temperature of the flame and opens the baffle at the junction between the gas valve and the pipe. Only when the normal temperature is sensed will the gas pass through so that the gas stove can ignite normally.

If there is a problem with the thermocouple, if the fire hole is carbonized.

If the fire hole is blocked or the fire hole is not aligned with the feedback needle, the flame will not be able to burn the feedback needle.

2.Thermocouple aging: A thermocouple is a feedback device, which is also described above.

If the thermoelectric occasionally has quality problems or damage, it will naturally fail to ignite properly. If it ignites and then extinguishes, it must be normal. If this happens, you can carefully check whether the thermocouple is damaged or if the quality of the thermocouple you bought is too poor.

1. The gas stove has automatic gas cut-off protection, because the protection probe detects that the fire has been extinguished, and automatically cuts off the gas. 2. 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. 3. Solution:

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. If the flame-out protection induction pin is faulty (skewed or faulty line), it is recommended to find a professional maintenance personnel to deal with it.

The reasons may be: 1. If the circuit is in poor contact, it is easy to cause the flameout or not to start, and it is necessary to check whether the lower circuit is normal. 2. It may be that the battery of the gas stove runs out and causes it to turn off automatically, and the battery needs to be checked and replaced.

3. It may be that the fire outlet of the gas stove is blocked, resulting in the automatic extinguishing of the gas stove. The outlet valve needs to be cleaned. 4. It may be that the position of the ignition needle has deviated, in normal use, the distance between the ignition needle and the fire cover is required, if the deviation is too much, it may cause the gas stove to not ignite.

You need to find a professional maintenance personnel to check and adjust. The gas stove should be kept dry, the gas stove can not leave the kitchen during use, and the parts inside the gas stove should be kept dry, otherwise it is easy to cause damage to the parts, the kitchen is a place that is easy to get dirty, it is easy to be contaminated with oil, etc., the gas stove is placed for too long, and the ignition needle is easily stained by the oil, so you need to clean the oil scale of the ignition needle, and then try to ignite. You can check whether the positive and negative poles of the battery box are rusty, whether the line is in poor contact, if there is any, you need to remove the rust, connect the line accurately, and check whether the battery has electricity.

This is also the direct cause of the flameout, check whether there is gas, if there is a problem, then judge whether it is a battery problem, check that there is no electricity, you need to replace the new battery, check whether the pipeline is blocked, once blocked, you need to check the gas valve, usually you can smell the gas stove and the gas stove does not catch fire is likely to be gas blockage, you need to dredge it in time to use it normally.

The solution to the automatic extinguishing of the gas stove in 20 seconds:

1. The solution to the gas stove without electricity.

The blockage of the gas pipe causes the gas stove to go out, which is generally manifested as being able to smell the smell of gas, but the gas stove just can't be opened, and it is likely to be caused by the blockage of the appearance. If this is the case, dredging work is needed to maintain the normal input of gas.

2. The solution to the gas stove is out of gas.

Some experienced people may be aware of this problem, but some people may be more negligent, maybe it is the daily life experience or the work is busy and often forget to check the fault, so when the gas stove goes out, you must check to see if there is still gas, if you find that there is no gas, you must add gas as soon as possible to use it normally.

3. Solution to overvoltage protection of gas stove.

Overpressure protection function, if the pressure is too large, it will automatically stop using, and then replace a pressure reducing valve. If it still can't be used normally, call the after-sales service ** to call a professional to repair it at this time.

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.

The gas stove burns for a while and then turns off automatically, which may be due to the fact that the extinguishing grip on the right side is in effect. 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 furnace heads will cut off the main gas circuit to prevent accidents.

Specific solutions.

The 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;
