How To Deal With The Problem Of Letting Go Of The Gas Stove And Turning It Off
Today's household gas stoves are becoming more and more high-end and smart, and they are also equipped with automatic flameout protection devices in terms of safety! The feedback from daily use is very good and well received by consumers. However, whether you buy a well-known large brand gas stove or a small or medium-sized brand gas stove, you may encounter some malfunctions caused by the flameout protection device of the gas stove. Today we will talk about the reasons why gas stoves automatically shut down when the fire switch is turned on during use or automatically shut down within about one minute. We will also talk about the reasons why gas stoves automatically shut down irregularly during use, possible faults and troubleshooting. method.
The gas stove is composed of several major parts, namely the panel, bottom box, solenoid valve, burner head, fire cover (flame distributor), air pipe, valve body assembly (the flameout protection device is directly integrated with the valve body assembly), Pulse igniter, ignition needle, induction needle, battery, connecting wires for various components, etc. Each component has its own function. The causes of gas stove flameout failure involve components such as solenoid valve, pulse igniter, battery, burner head, fire cover (flame distributor), ignition needle and wire, flameout sensor needle and money, and valve body assembly switch. Therefore, when we encounter a gas stove failure, we must first investigate these components.
If the gas stove automatically shuts down, you must first rule out the flameout caused by the gas stove having no gas or gas outage. Then we will investigate and deal with it step by step according to the following situations.
Problem 1: The gas stove lights up and goes out when you let go:
If the gas stove is on fire, turn off the flame immediately after releasing the knob switch with your hand, and then press and turn the knob switch with your hand to still light it. However, the gas stove will turn off as soon as the knob switch is loosened. This fault lies in the flameout protection device, flameout sensor pin, flameout sensor pin, and flameout protection device. Make sure to connect the three parts of the cable. This is because the safety flameout protection device of the gas stove is in a closed state, and the flame temperature is not sensed or the connection line is not connected, causing the flameout protection to not start normally. When we press the switch of the gas stove with our hands to light the fire, it is because the gas stove is forced to work by an external force. Once there is no external force of hand pressure, the internal valve of the gas stove's flameout device is still not open, and the gas is trapped inside the valve body. If it is cut off and not allowed to flow through, the flame on the burner of the gas stove will naturally go out.
The processing methods can be checked in the following order:
1. Make sure to press the ignition switch knob for 3 to 5 seconds each time to ignite, so that the gas stove's flameout device has sufficient valve opening time.
2. Check that the burner cover is placed in the correct position and is at a moderate distance from the flameout sensor needle (when the flame of the gas stove is burning, the flameout sensor needle position is just in the flame, which means it is at a moderate distance). If you find dirt on the sensor needle or fire cover, wipe the sensor needle with a dry rag to remove the dirt.
3. Check whether the battery needs to be replaced. When the battery power is weak, the ion-extinguished gas stove will not be able to burn normally because there is no current circuit generated by the battery. At the same time, the electric spark generated by ignition is also very weak. Generally, the average service life of a gas stove battery is 6-12 months.
4. Adjust the damper blade under the gas stove so that the tip of the induction needle for flameout protection can be wrapped in the flame when the flame is burning.
5. If none of the above methods can solve the problem, you need to check whether the internal connection lines of the gas stove are loose or fallen off, or replace the lines directly.
6. Check whether the gas stove valve body assembly switch is damp or damaged. (About 60% of gas stoves that stall after letting go are caused by problems with this component, which can be solved by directly replacing the valve body assembly of the same model!)
Problem Situation 2: The gas stove can be used normally when it is on fire, but it will automatically turn off during use:
This special situation is that the gas stove can be used normally, but automatic flameout occurs occasionally (irregularly) during use. The troubleshooting method is as follows:
1. Check whether the convection of air flowing between the gas stove and the window is too strong, causing the flame of the gas stove to deviate from the sensor needle and extinguish.
2. Check whether the battery has sufficient power. If the battery is used for more than half a year, replace it with a new one in time;
3. If the damper of the gas stove is too large, it is easy to cause the flame to be higher than the flameout sensor needle. Turn down the air inlet of the damper. At the same time, check whether the stove cover and flameout sensor needle are installed correctly and whether there is dirt, etc., and adjust and clean them.
4. Check whether the internal circuit of the gas stove is in poor contact. You can directly replace the corresponding circuit, flameout sensor pin and connecting wire.
