What should I do if the natural gas stove is not easy to catch fire for a long time

It is a common thing in our life that the gas stove doesn't catch fire. There are many reasons. If you use it for a long time, it will sometimes break down, but when you check the reason, you must be careful. So what if the gas stove doesn't catch fire? Let's look at the solution to this problem.

Working principle of gas stove

The fire protection method of gas stove is thermocouple, and its working principle is thermocouple heating.

It will generate thermoelectric potential and make the solenoid valve work. Specifically, when the knob is pressed and a small fire is ignited, the thermocouple is heated by its flame and generates thermoelectric potential. Thermoelectric potential is introduced into the electromagnetic coil through the wire, resulting in a magnetic field.

The electromagnetic valve is attracted, the gas valve is opened, and the combustion passage is opened to maintain its normal combustion. Once the strong wind or soup overflows, the flame goes out, the thermoelectric potential of the thermocouple quickly drops to zero, the coil loses power, the solenoid valve fails and is bouncing.

Under the action of the spring, it quickly resets, and the valve closes the gas path and terminates the gas supply.

Common causes of non-ignition of gas stoves

1, the pulse igniter has no battery.

2. The distance between the ignition electrode and the induction electrode is inappropriate or polluted.

3, the air pressure is too high, resulting in too fast air flow speed, impact EDM.

4, the ignition nozzle is too big, the nozzle is too big to cause too much air flow, which affects the electric spark.

5. The stern head is damaged, which causes the damaged part to ignite too close.

6. The ignition output cable is not firmly connected with the porcelain head.

7. The total internal impact block of the switch is worn or broken.

8. The pulse ignition microswitch has poor contact.

What if the gas stove doesn't catch fire?

First, the left side can strike a fire normally, indicating that the battery is fine.

1, the one on the right can't be hit, and the ignition sound can't be heard, that is, the microswitch on the valve body is broken or dirty, which needs cleaning and professionals.

2. The igniter is broken. There are two coil devices in the igniter. The one on the right may not work and needs professional maintenance.

Second, if the ignition sound can be heard during ignition, there may be something wrong with the ignition needle and distributor.

1, first look at the fire needle, magnetic white, whether there is a spark when igniting, whether the strength of the spark is the same as that on the left, if not, replace the ignition needle.

2. The hole of the distributor is not aligned with the spark of the ignition needle. Place the distributor in the same way as on the left.

Third, if you don't get angry, see if the discharge needle discharges.

1. If the discharge needle does not discharge, it means that the discharge needle is faulty and should be replaced.

2. If the discharge needle discharges, it means that the valve body is faulty and should be replaced.

Fourth, if you are angry,

1. If it can burn normally, it means that the position of the igniter is on the high side, so the user should be instructed to gently press the igniter down a few times, and then put it on the pot rack.

2. If there is fire, but the flame is too weak to reach the burner, the gas pressure is too low. Users of liquefied gas stoves suggest replacing new pressure reducing valves, while gas and natural gas should be reported to the gas supply company.

3. If there is a fire, the flame can reach the fire cover, but there is no fire, indicating that the valve body is blocked, and instructing the user to dredge the nozzle with fine wire.
