What s the deal with a gas stove that turns off automatically after a while?

You need to explain the use clearly, and it is recommended that you take a close look at your gas stove manual. The principle of flameout protection for different types of gas stoves is different. There are two common types: ionic flame-out protection and thermocouple safety flame-out protection.

For the thermocouple type, if the ignition time is short after ignition, let go in advance, because the temperature is not high enough, the thermoelectric potential (voltage) generated by the thermocouple is not enough to maintain the solenoid valve to continue to engage, which will cause the solenoid valve to close the air supply and turn off the flameout. On the other hand, ionic flame-out protection conducts electricity by the flame, and if the flame is extinguished for some reason (windy or doused by water spilled from the pot), it is also protected by a circuit that cuts off the solenoid valve that supplies air. So you need to read the instructions carefully and check the reasons against your actual situation.

Dear users: Today, I will answer the question based on my own practice, please see if it is the same as your situation. The gas stove was turned on for about 1 minute, and it always turned off automatically, and I checked it repeatedly and found no problem.

It can only be opened, checked item by item, and there is no fault in the line. Couldn't use it for days. Then it occurred to me that there was a problem with the fire sensor?

Sure enough, it was found that the fire sensor was too close to the fire outlet, which was the inner flame of the fire, and the temperature was low, so it may not be able to sense it, and mistakenly thought that the flame was extinguished, and started the shutdown program. I'll adjust the distance between it and the flame, a little farther away, so that it can sense the outer flame, and the problem is solved. I hope it can be useful to you, first to see if the sensor is too close or too far away, and then check the circuit or replace the device.

If it's useful, pin it.

The problem lies in the fact that the flame-out protection device cannot receive the source heat normally, and the air supply solenoid valve cannot be opened normally. Adjust the damper so that the ratio of air to gas is appropriate.

How to check the gas stove for malfunctioning:

1. The gas source switch of the gas stove is not turned on or the air pressure is insufficient. Solution: After turning off the stove switch, check whether the front stopcock valve and the entrance switch of the gas stove are open, if not, try to light the light again after opening an account.

2. The ignition needle and hot spot of the gas stove are occasionally polluted or out of power. Solution: Check whether there are sparks when the stove is ignited, if there is no replacement battery, if there is a spark, it may be that the air inlet and nozzle of the regulator are blocked by rust, hindering the gas flow out of the bottle, and replace the qualified regulator.

3. The position of the fire cover of the gas stove is not placed. Solution: Check whether the fire cover of the gas stove is flat, closed, and whether the umbrella is aligned with the ignition needle, if it is not placed, you can put it in the exact position after the fire cover has cooled.

4. Oil stains and food residues block the fire holes, and the ignition groove is blocked, resulting in no fire. Solution: Clean up the dirt that blocks the fire hole and ignition groove.

5. The size of the damper of the gas stove is not suitable, the damper is not easy to ignite, and the small damper will not burn sufficiently and yellow fire will appear.

In our house, there are often situations where the gas stove on the right side does not turn on or goes out after a while.

Reason for automatic extinguishing of gas stove:

1. 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. The incineration needle is 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 gas pressure will also cause the gas stove to go out naturally.

Solution: Replenish gas or air pressure.

4. Once the electronic lighter is damaged, it will not be able to work normally, and the gas stove will be extinguished naturally.

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 work of the gas stove.

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

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

Solution: Ask a professional to replace the sensor needle.

The reasons why the gas stove will automatically extinguish after a while after it is ignited: 1. The gas stove flameout protection induction needle is faulty, the induction needle is skewed, resulting in poor contact, or the usual stew overflowing pot soup is attached to the flame-out protection needle and the response is slow; 2. The fire cover is not placed well and the stove plate is too dirty, and the flame against the probe cannot be burned. Workaround:

1. Check whether the gas valve is normal; 2. Check whether the probe on the stove can be burned by the burning flame, and if not, it will be extinguished. 1. The stove plate is dirty, and the fire against the probe can't burn the probe; 2. The damper adjustment is not suitable, so that there is no gas in the fire facing the probe, and the damper needs to be adjusted until there is a flame at the probe site to continuously burn the probe. [Tips] 1. The gas stove must be cleaned regularly, and it cannot be cleaned after a layer of impurities has accumulated on the cooktop.

2. Pay attention to wipe with detergent, but do not wipe the glass countertop with steel wool balls, which is easy to cause scratches, damage the protective layer of the glass countertop, and make the countertop easy to burst. 3. Pay attention to maintaining ventilation around the damper.

This situation is due to the protection detection after the gas stove is ignitedThe temperature of the sensor probe has not been burned by the flameThe voltage generated is not enough to control the ignition circuit to stop ignition, or in order to prevent ignition failure and solenoid valve failure to work normallyThe time of ignition was deliberately extended to ensureAfter the ignition is reliable, the temperature of the sensor probe is high enough, and the solenoid valve can work reliably, the ignition is stopped again, which improves the reliability of ignition.

Answer 1: Poor circuit contact. This is a problem that is easy to ignore, but it is often encountered among many old users, mainly to check whether the positive and negative poles of the battery box are rusty, and whether the line is in poor contact.

Solution: If the circuit of the cooker is not in good contact, the rust needs to be removed and the line should be connected accurately.

2. Overvoltage protection. Many stoves have an overvoltage protection function, which will not be activated once overvoltage.

Solution: If the stove is overpressure protected, then you need to change a pressure reducing valve to try.

3. Pipeline blockage. This is a very common problem, once the pipe is blocked, it is necessary to check the gas outlet valve, generally speaking, you can smell the gas odor and the stove does not catch fire, it is likely to be a gas blockage.

Solution: The stove pipe is blocked, then the pipe should be unblocked or replaced.

4. The micro switch is damaged. At this time, there is a small place in the stove, but it is more difficult to repair than the usual faults, and in general, it is not recommended for the owner to repair it himself.

Solution: The micro switch of the stove is damaged, this is a delicate and professional work, and it is best to ask a professional person to solve it.

5. The ignition needle is dirty. The kitchen is a place that is easy to get dirty, especially if it is easy to be stained with oil, etc., and if the stove is left for too long, the ignition needle will be easily stained by the oil. Workaround:

In this case, it is necessary to clean the grease of the ignition needle before attempting to ignite. 6. Improper position of the ignition needle. If you want to ignite the fire, the stove has certain requirements for the distance between the ignition needle and the fire cover, and once the distance deviates too much, the stove will not catch fire.

Solution: Generally speaking, the distance between the ignition needle and the fire cover is 4-6mm, and the fire hole should be aligned. 7. The high-voltage line of the stove is aging.

The stove has a high-voltage line and its connection, once the high-voltage line is aged, it is easy to make the stove can not catch fire. Solution: At this time, only a set of high-voltage protection is required, which should be observed more in ordinary life.

It is possible that there are these reasons, and I have written down the solution as well. You can refer to.

The answer to this situation is that after the gas stove is ignited, the temperature of the sensor probe of the protection detection has not been burned up by the flame, and the voltage generated is not enough to control the ignition circuit to stop the ignition, or in order to prevent the ignition failure and the solenoid valve from working normally, the ignition time is deliberately extended to ensure that the ignition is reliable, the sensor probe temperature is high enough, and the solenoid valve can work reliably, and the ignition is stopped again, which improves the reliability of the ignition.

Hope it helps!

This situation may be caused by the wrong position or problem with the sensor needle above.

The feedback probe falls off, and the temperature signal cannot be fed.

The gas stove will be extinguished after a while, and it may be that the gas or gas pressure is insufficient to cause the gas stove to go out naturally, and the gas or gas pressure can be replenished in time to solve the problem that the gas stove will be extinguished after a while. It is possible that the electronic lighter is damaged, and a new electronic lighter should be replaced in time, so that the problem of the gas stove being lit and extinguished for a while can be solved. It is possible that the induction needle is broken, and it is necessary to ask a professional who repairs the gas stove to replace the induction needle, so that the problem of the gas stove being extinguished after a while can be solved.

The incineration needle is not properly positioned The gas stove will be extinguished after a while, which may be caused by the improper orientation of the incineration needle, and the interval between the incineration needle and the fire cover should be controlled in the range of 4-6mm, and the fire hole needs to be aligned when ignition, so that the problem of extinguishing the gas stove after a while can be solved.

What's the matter with the gas stove that is still on fire after it is lit, and it will automatically go off after a while?

There are usually three possibilities in this situation: 1. Flame-out protection induction pin failure (skewed or line fault). Workaround:

This situation needs to be repaired to solve, please call the local service **, if it is within the 1 year warranty period, it should be free. 2. Due to the overflow of the pot, the soup adheres to the flame-out protection needle, which affects the induction and causes slow response. Workaround:

Clean the flame-out protection. 3. Because the fire cover on the stove head (ring-shaped, with copper black objects with fire holes around) is not placed in place after cleaning (in addition to the holes of the same size around the fire cover, there are two small holes next to each other below, which should be facing the ignition needle), resulting in slow gas conduction and slow ignition. Workaround:

Reinstall the fire cover.

The air supply valve does not need to be dredged, or the gas stove needs to be dredged after a long time!
