Why does the flame of the home stove go out?
It must have happened to you that while cooking and working with a domestic or industrial stove, you suddenly faced the gas flame turning off; A discouraging event that makes you want to look for simple solutions as soon as possible.
Since this problem can have several causes, such as a broken thermocouple or other technical defects, therefore, in this article of safe flame brook, we are going to examine some of the common reasons that cause the flame of the stove to go out.
10 reasons for the flame of the home gas stove to go out
In addition to ruining your recipe by changing temperature, a stove that keeps shutting down unexpectedly can be dangerous and emotionally draining.
Therefore, in the following, we present a list of the reasons for the shutdown of the domestic and industrial stove, along with its details, which can guide you in identifying the problem and fixing it.
1. Failure of temperature sensor or thermocouple
First of all, check the thermocouple of the domestic or industrial stove; Because it may need to clean its thermoelectric converter. Thermocouple failure can cause gas burners to rot. In some cases, when the gas flame is extinguished by wind blowing or liquid spilling on it, if the thermocouple fails and the gas flow is not cut off, it can cause an accident and fire.
But there is an easy way to detect the failure of the temperature sensor:
• Press the gas volume.
• The flame on the burner must be lit.
• When you press the volume, the home oven will work properly.
• But after releasing the gas volume, the flame goes out again.
This means, the thermocouple of your industrial or home gas stove is not working properly; Therefore, before replacing the part, try to clean the converter head, which is located under the flame divider, with sandpaper and see if it is positioned correctly; This piece should be close to the burner.
If there is no change by doing this, you need to install a new thermocouple.
2. Pollution of the nozzle and its blockage
Stove nozzle blockage
Another factor that causes the flame of the home gas stove to go out is the nozzles being dirty; So, to clean it, first turn off the gas and let the stove cool down for some time.
Close the gas valve and be sure to open the kitchen or room windows and then do the following steps:
• Remove the gas grates and remove the flame cover pieces.
• Inside the burner you will find a small hole; This is the nozzle.
• You can use a thin wire or paper clip and a toothbrush to clean the nozzle.
• When finished, put the flame cap and the nets back in place.
3. Low gas pressure
Low gas pressure of domestic gas stove
Another common reason for industrial and domestic gas stoves to go out is low gas pressure. This can be caused by a number of factors, including a problem with the gas line or regulator.
When the gas pressure is low, the flame may be weak and flicker or may even go out completely.
To fix this problem, start by checking other gas appliances in your home to see if they are affected. If these devices also had low gas pressure, then the problem may be with the gas line or regulator, and you should contact a technician to check and repair it; But if only your home gas stove has this problem, adjust the gas valve to increase the pressure. If the pressure does not adjust, it may be necessary to completely replace the gas valve.
4. Clogged gas line
Clogging of the gas line or valve can also cause the two-burner to several burners to shut down. This can happen when debris or sediment builds up in a line or valve and blocks gas flow; The result of this is the weakening or complete extinguishing of the flame.
To solve this problem, first turn off the gas valve and disconnect the gas line from the home gas stove. Use a soft brush to gently clean the inside of the gas line and valve. After cleaning the gas line and valve, reconnect them to the home gas stove and turn on the flame again.
5. Faulty gas regulator
A faulty gas regulator can also cause the flame of a home gas stove to go out. The gas regulator is responsible for regulating the flow of gas to the gas stove, and if it does not work properly, it can cause the weakening of the three-burner gas or its complete shutdown.
To solve this problem, you need to replace the gas regulator. This work requires more expertise and is a complex solution that may require the help of an expert; Therefore, if you suspect that this problem has arisen for your home gas stove, then it is better to contact a professional technician.
6. Failure of gas volume
But another reason for four or five burner gas turning off may be the failure of the gas knob or volume. Normally, flame ignition should start five seconds after the thermocouple heats up; Otherwise, you need to replace it.
On the other hand, insufficient pressure can result in poor spring compression and flame out when the throttle is released. As a result, a large gap is created between the end plate of the electromagnet core and the valve armature.
To solve this problem, remove the plastic handle of the home stove by pulling it towards you. Then put an additional steel washer on it; Its thickness should be 1 mm. Using an additional gasket allows you to reduce the gap size when pushing the gas volume.
7. Dirty burners
Dirty industrial and domestic stove burners
One of the most common reasons for the flame of a home gas stove to go out is the dirty burners and cast iron grids of the gas stove. Over time, food residue and grease can build up on burners or grates, causing the flame to dim or go out completely. This can also cause your food to undercook, which is another frustrating problem.
To solve this problem, turn off the home stove and let it cool completely. Remove the nets and parts of the flame cover from the gas stove and put them in warm soapy water for at least 15 minutes. Use a soft brush to gently remove any dirt, then rinse thoroughly with water and dry. Once the burners and grates are clean and dry, reassemble them and turn the stove back on.
8. Breathing gas hoses
Sometimes, excess air in gas hoses and pipes will cause your gas flame to go out; Therefore, you should ventilate the gas hoses.
To solve this problem, you can turn on the single large flame of the gas stove for a while to expel the air from the gas pipes.
But this work, because it may be accompanied by the release of some gas, it is better to ask a technical expert to ventilate the pipes of your gas stove.
9. Defective spark plug
A candle in a home gas stove is responsible for creating a flame by sparking. When this candle is broken or defective, it cannot function properly in an industrial or household gas stove, and as a result, problems arise in creating a gas flame; Therefore, it is better to easily check the condition of the candle that is next to the burner and is often made of ceramic by looking at it; See if there are any cracks or splits on the spark plug.
If you find that there is a problem with the gas stove spark plug, you should seek to replace this part so that the sparking and flame creation process can be done correctly.
10. Failure of the spark generator
Stove spark generator problems are common with some models of gas-burning appliances, including stoves that use less automatic or pilot ignition systems.
In this case, with the failure of the spark generator, the candles of the gas stove cannot produce a spark and as a result, no flame is created. This problem may be caused by faulty flame microswitch connections, dirty electrode and burner cap, cracked and broken electrode, incorrect and inappropriate wiring, or weak connections in the burner electrode and electrode sockets.
To fix this problem, it is better to replace the generator and the ignition module completely.
Conclusion
Various models and brands of gas stoves are available in home appliance stores, regardless of their quality, reliability and performance, sooner or later they may break down and their gas flame goes out due to improper or long-term use.
Therefore, you can check the common causes that we mentioned in this article if you face this problem and the flame of your home gas stove goes out.
