Why the gas stove can t catch fire and how to deal with it?

The reasons why the gas stove can't catch fire are: 1. Gas problemThe fuel used in the gas stove is gas, if there is a problem with the gas **, then the gas stove can't catch fire. As for the problem of gas **, most of the time it is a lack of gas balance.

Of course, there are also temporary emergency repairs and gas outages of pipeline gas, gas valves at home that are not opened, and so on. Pay special attention to one item, that is, if you use a gas alarm with an automatic shut-off valve, the shut-off valve will automatically cut off the gas due to false alarms**. These are all problems with gas**, and they are also an additional reason why the gas stove does not catch fire.

2. The battery power of the gas stove is low, and the current gas stove is electronic pulse ignition, when the battery is insufficient and cannot produce electric sparks normally, it will not be able to ignite, which everyone may know. However, there is another situation, that is, when the battery power of the gas stove is relatively low, it can still make an electric spark, but the gas stove cannot ignite. In fact, this is because the battery of the gas stove is low, which is not enough to open the solenoid valve of the gas stove, so it cannot ignite, which is also a puzzling, and there is indeed a relatively common reason why the gas stove cannot ignite.

3. The gas stove itself is faulty, and the gas stove itself is faulty, and it may not catch fire. One of the more common reasons for this is that there is a problem with the automatic flame-out protection device of the gas stove. For example, the probe of the automatic flame-out protection device is dirty, and the probe connection is false.

There are also reasons such as the blockage of the fire hole at the probe of the gas stove head. Of course, there are also gas stoves that have damaged ignition systems, solenoid valves that are stuck, ignition switches that are faulty, etc., but they are not common.

The gas stove does not catch fire, either because the line connecting to the natural gas is blocked and there is no gas, or there is a problem with the lighter and battery, which cannot produce sparks and make the gas stove work normally. Of course, it is not ruled out that the solenoid valve of some gas stoves is faulty, and the natural gas inlet is closed, resulting in the gas stove not catching fire.

Solutions to the above problems, one. After turning off the fire control switch of the gas stove for inspection, check whether the air intake switch and the entrance switch of the gas stove are open, if not, turn on the air intake switch and the entrance switch of the gas stove to try to ignite;

Two. Close the intake valve, then turn on the fire control switch to see if there is a spark from the lighter, if not, then you need to replace the battery on the cooktop, or replace the lighter.

Three. The air inlet and nozzle inside the pressure regulator are blocked by rust, which hinders the outflow of gas in the bottle, and it is recommended to replace a qualified pressure regulator; The fourth point is that the fire hole of the burner cover is blocked by dirt, which hinders the flow of mixed gas in the burner.

Four. The automatic flame-out function of the solenoid valve of the gas stove fails, and the wiring gasket in the valve body cannot be energized, resulting in the solenoid valve of the gas stove not working. This requires a professional maintenance personnel to repair or replace a new valve body.

Friends with strong hands-on ability can update a valve body by themselves. After changing the solenoid valve, you can use thick soapy water to check whether there is air leakage.

Either the battery is dead, or the gas switch is failing.

1. There is no gas

Most people will have a bottom in their hearts about this, but some people may be sloppy, or busy with work, and often forget, so when the stove does not catch fire, the first thing to check is whether there is still gas. If the bottled gas is out of gas, it must be refilled; In the case of piped gas, make sure the valve switch is open.

2. The battery is dead

This is a problem that is usually easy to encounter, and it is also a problem that people are generally concerned about, and if you find that the ignition is not on fire and there is no clattering sound, you must check whether the battery is charged. If the stove battery is not available or runs out, you only need to replace it with a regular No. 1 battery.

3. 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. If the circuit of the stove is not in good contact, the rust needs to be removed and the wiring should be connected accurately.

Ignition method: There are two ignition methods for gas stoves: electronic pulse ignition and piezoelectric ceramic ignition. Electronic pulse ignition consumers are generally very familiar with the ignition device used in most embedded stoves, which is ignited when twisted to a certain position, which is very simple and convenient, and the ignition hit rate is high, generally 100%, but this way requires battery replacement.

Piezoelectric ceramic ignition is mostly used in desktop stoves, and the biggest advantage is that it does not require batteries. However, the success rate of ignition is related to the ambient humidity, and it is not easy to ignite when the humidity is high. In addition, the ignition needs to be pressed and held to ignite, which is not as fast as the electronic pulse ignition.

There is no gas. Most of the cases where the gas stove can't catch fire are because there is no gas, and when there is no gas, it naturally can't catch fire.

Solution: Just pay the gas bill.

Clogged pipes. In many cases, if the gas pipeline is clogged and cannot be transmitted to the gas stove, it will also cause the fire to fail.

Solution: In the case of pipeline blockage, you need to find a professional maintenance master to check and repair. It should be noted that the pipeline is blocked, and there will generally be leakage, and it is not possible to encounter an open flame, so it is best to close the electric switch during the inspection.

The battery is dead. The battery of the gas stove is also one of the reasons why the gas stove cannot catch fire, which is mainly manifested in the fact that there is only sound and no flame.

Solution: Replace the old battery with the corresponding new battery.

Thermocouple aging.

Several successive ignitions are required and may not always be successful. This situation is mostly caused by induction gas stoves with thermocouples, which are caused by the long-term use and aging of thermocouples.

Solution: Replace the thermocouple induction pin.

Poor contact of pulse ignition micro switch.

The ignition of the gas stove is sometimes normal and sometimes abnormal, and this situation is mainly caused by the poor contact of the pulse ignition micro switch.

Solution: Adjust the pulse ignition micro switch to solve.

Poor circuit contact.

Although the design principle of the gas stove is simple, it also involves a simple circuit, and if the circuit is not in good contact, it may also cause the gas stove to fail to ignite.

Solution: Find a maintenance person to check the circuit, and at the same time check whether there are traces of rust in the battery box, and if so, remove the rust and restart.

The high-voltage line of the stove is aging.

Gas stoves also need electronic wiring, and the aging of high-voltage wiring will also lead to failure to ignite.

Solution: Due to the small installation space of the line and the relatively hidden location, it is generally a professional after-sales master to carry out inspection and maintenance.

There is a problem with the ignition needle.

The ignition needle of the gas stove is also prone to problems, such as the ignition needle is displaced, dirty, etc., which are one of the reasons why the gas stove cannot catch fire.

Solution: It is necessary to clean and check the position of the lighter needle in time.

Overvoltage protection. Since the gas stove uses natural gas, it needs to use a pressure gauge, etc., so if the pressure is exceeded, the overpressure protection will be automatically turned on, and the fire will not ignite.

Solution: Generally speaking, when the pressure is relieved and lowered to a normal value, it can be used.

The position of the fire cover was not placed accurately.

The position of the fire cover of the gas stove is not accurate, and the gas stove cannot catch fire, which is generally easy to appear in the first use of the new gas stove.

Solution: It is recommended to check whether the fire cover is flat, whether it is closed, and whether the umbrella is aligned with the ignition needle.

The fire holes and ignition grooves are blocked.

The gas stove is only half of the fire, or only the inner ring has a fire and the outer ring has no fire, because after the gas stove has been used for a long time, oil stains and food residues have blocked the fire hole, resulting in a partial non-fire, while the outer fire cover has no fire is usually due to the ignition groove is blocked.

Solution: Take a clean toothpick and dredge the fire hole and ignition groove from the inside out.

1. There is no gas in the gas stove.

When the gas stove cannot be ignited, the first thing to consider is whether the gas source is sufficient. If there is no gas, there will be no spark when the switch is turned on. There are several possibilities for this to happen, and it is possible that the gas pipeline is clogged and the gas cannot be reached.

There is also a possibility that because of an emergency, the gas company closed the natural gas ** valve. At this time, we can first check the gas meter to see if it is in normal working condition. If it shows that it is not in normal working condition, you can call a staff member to come for repair.

Second, the gas stove battery is depleted.

For households, a depleted gas stove battery is also one of the reasons why it cannot be ignited. This should be considered when ignition is observed when there is no sound but no flame appears. The battery only needs to be replaced and the gas stove can be reused.

3. Poor contact of no electrical circuit in the gas stove.

If ignition is still not possible even if both gas and electricity are available, you can check the internal wiring and the two poles of the battery box for rust and poor contact. This is because the inside of the gas stove often has some circuits, which are easy to cause poor contact under long-term oxidation. In this case, it is only necessary to remove the rust and eliminate the poorly touched parts, and it can be used again.

Fourth, the ignition device internal failure.

At present, the main ignition time of gas stove is divided into two kinds: electric pulse ignition and piezoelectric ceramic impact ignition, if there is a discharge spark in the gas stove at the time of ignition, it indicates that the ignition part is normal. But if there is no spark from the discharge, it is a sign that the ignition of the gas stove is malfunctioning. If such a problem occurs, it is necessary to seek help from professional maintenance personnel.

5. Gas stove gas circuit system failure.

If the spark is normal but cannot be ignited when the gas stove is ignited, it is also possible that the ignition head is blocked, and the combustible gas cannot be sprayed out, so the ignition of the gas stove fails. The main reason for this is that piezoelectric ceramic impact ignition devices are commonly used in old gas stoves, and there is only a small hole in the gas system for gas to flow out. If this is the case, it is necessary to unblock the vent to restore the health of the gas stove.

Sixth, there is a problem with the ignition needle.

Since the kitchen is washed by oil fumes every day, it is easy to accumulate oil stains. In such a situation, it is easy to cause the ignition needle to displace. At this time, it is necessary to clean the gas stove in an all-round way, and continue to use it after the oil is washed off.

However, the working environment of the ignition needle is often under the calcination of large fires, and if you see that this part has been deformed, it can be replaced.

1.Check for gas. Sometimes, you may forget to buy gas because you are too busy with work, so naturally you can't light the fire. Just pay the fee and buy gas to start a fire.

2.Check that the battery is charged. Gas stoves require batteries, so you can watch for sparks when the gas stove is on fire.

If the sound is soft and weak, the electrical frequency will be slower than before and there will be a clicking sound. If this happens, it is most likely that the battery on the gas stove is running low. Replace the battery with a new one.

The positive and negative electrodes in the battery slot can also rust, resulting in poor contact. Simply use gauze to gently wipe off the rust.

3.Check that you are doing it correctly. Current electronic ignition gas stoves all have flame-out protection, which needs to be held down for 5-10 seconds during ignition, and can only be released when the sensor needle is activated.

4.Check that the fire splitter of the gas stove is placed correctly. If the buckle is displaced, it will not only release the flame, but will also cause the flame splitter to burn and deform.

Clause. 1. Is there any gas. The first thing to check is whether there is still gas, and if not, add gas.

Clause. Second, the battery has no electricity. Find out if the battery has power, if not, just replace it with a normal No. 1 battery.

Clause. 3. Poor circuit contact. Check whether there is rust on the positive and negative poles of the battery box, whether the line is in poor contact, and the rust needs to be removed and the line should be connected correctly.

Clause. Fourth, overvoltage protection. Many gas stoves have an overpressure protection function, and once the overpressure is not activated, then it is necessary to change a pressure reducing valve to try.

Clause. Fifth, the pipeline is blocked. Once the pipe is blocked, the outlet valve should be checked and the pipe should be unblocked.

Clause. 6. The micro switch is damaged. The micro switch is in a small place of the gas stove, and it is more difficult to repair than the usual fault, so it is best to ask a professional to solve it.

Clause. 7. The ignition needle is dirty. If the gas stove is left for too long, it is easy to get dirty with oil, so it is necessary to clean the grease from the ignition needle and then try to ignite it.

Clause. 8. Improper position of the ignition needle. Once the deviation distance is too much, it will cause the gas stove to not ignite, generally speaking, the distance between the ignition needle and the fire cover is 4-6mm, and it should be aimed at the fire hole.

Clause. 9. The high-voltage line has deteriorated. At this time, it is only necessary to add a set of high-voltage protection, which should be observed more in ordinary life.

1. Check if there is any gas. See if the gas company stops supplying gas due to the non-payment of gas, and you can pay the gas bill.

2. The gas source switch of the gas stove is not turned on or the air pressure is insufficient. After turning off the stove switch, check whether the front valve and the entrance switch of the gas stove are open, if not, try to fire again after opening an account. 3. The ignition needle and hot spot of the gas stove are occasionally polluted or out of power.

Check whether there is a spark when the stove is ignited, if there is no replacement battery to try, 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, replace the qualified regulator.

4. Oil stains and food residues clog the fire holes. If the ignition groove is blocked, the fire will not be fired, and the dirt that blocks the fire hole and ignition groove can be cleaned up.

Expand your knowledge: Natural gas is a gaseous fossil fuel composed primarily of methane. It is mainly found in oil and gas fields, and also in small quantities from coal seams.

Natural gas [1] is also buried in underground enclosed geological formations, some of which are stored in the same stratum as **, and some of which exist separately. For natural gas stored in the same layer as **, it will be extracted together with **. The main use of natural gas is as fuel, which can make carbon black, chemicals and liquefied petroleum gas, and propane and butane produced from natural gas are important raw materials for modern industry.

Natural gas is mainly composed of gaseous low molecular weight hydrocarbons and non-hydrocarbon gas mixture, with the acceleration of the implementation of natural gas reform, the "13th Five-Year Plan" vigorously promotes the gradual approach of natural gas development expectations, and the recent cooling weather has increased the use of natural gas, the development of natural gas will usher in a historic opportunity. On May 25, 2018, the National Development and Reform Commission announced that it would straighten out the residential gas valve stations and improve the natural gas mechanism from June 10.
