First, is there gas? If the gas stove doesn't catch fire, first check whether there is gas, and if not, add gas.

Second, whether the battery is charged. When it is found that the ignition is not bright, it is necessary to check whether the battery is charged. If not, replace it with an ordinary 1 battery.

Third, the circuit is in poor contact, mainly to check whether the positive and negative electrodes of the battery box are rusted and whether the circuit is in poor contact. If there is, it is necessary to remove rust and connect the wires accurately.

Fourth, overvoltage protection, many gas stoves have overvoltage protection function, once overpressure, they can't start, so try changing a pressure reducing valve.

Fifth, the pipeline is blocked. Once the pipeline is blocked, check the air outlet valve. Generally speaking, if the gas stove doesn't catch fire, it is likely that the gas is blocked. At this time, it is necessary to clear the pipeline.

Sixth, the microswitch is damaged. The microswitch is a small place in the gas stove, but it is more difficult to repair than usual. Generally speaking, it is not recommended for car owners to repair themselves. This kind of fine and professional work is best solved by professionals.

Seventh, the ignition needle is dirty, and the kitchen is easy to be dirty, especially easy to be contaminated with oil. If the gas stove is left for too long, the ignition needle is easily polluted by oil. At this time, it is necessary to clean up the oil on the ignition needle and then try to ignite it.

Eighth, the ignition needle is in an improper position. If ignition is to be carried out, the gas stove has certain requirements on the distance between the ignition needle and the fire cover. Once the distance deviates too much, the gas stove will not catch fire. Generally speaking, the distance between the ignition needle and the fire cover is 4-6mm, which should be aimed at the fire hole.

Ninth, gas stoves have high-voltage lines and their connectors. Once the high-voltage line ages, it is easy to make the gas stove fail to catch fire. At this time, you only need to add a set of high-voltage protection, and you should observe more in your daily life.

It is best to ask a gas stove professional to repair it.
