1. Gas shortage: If there is not enough gas in the gas bottle, of course, the gas stove won't light.
2. The battery is dead: If the battery is dead, it is normal for the gas stove not to catch fire.
3. Poor circuit contact: This is a problem that is easily overlooked, but many old users often encounter it, mainly to check whether the positive and negative electrodes of the battery box are rusted or not, and whether the lines are in poor contact.
4. Over-voltage protection Many gas stoves have over-voltage protection function, which will not start once it is over-voltage.
5. Pipe blockage: This is a very common problem. Once the pipeline is blocked, check the air outlet valve. Generally speaking, if you can smell the gas, the gas stove won't catch fire, and it is likely that the gas is blocked.
6. Damage to the microswitch: This is a small part of the gas stove, but it is more difficult to maintain than usual. Generally speaking, it is not recommended for car owners to maintain themselves.
7. Dirty ignition needle: The kitchen is a very dirty place, which is particularly vulnerable to oil pollution. If the gas stove is left for too long, the ignition needle is easily polluted by oil.
8. Improper position of ignition needle: Improper position of ignition needle of gas stove. If you want to ignite, 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 won't light.
Extended data
Gas stove is a method to supply natural air to the gap between the furnace body and the upper cover to supplement the shortage of air during combustion, so as to promote combustion and reduce the production of carbon monoxide and nitrogen oxides.
1. The furnace body is annular, and the upper surface of the inner periphery is provided with a mixed gas injection port; One end of the mixing tube is connected to one side of the furnace body, the other end is provided with an air conditioning port, and the middle of the air conditioning port is a gas input tube; The bellows in the middle and lower part of the furnace body is provided with a plurality of air injection ports for injecting the air blown by the blower upwards; A blower for blowing air through a motor is connected with the first bellows through an input pipe.
2. The top of the furnace body is covered with an upper cover, and a flame spraying area is arranged in the middle, and the flame is sprayed upwards through the flame spraying area; At least three convex seats are arranged above the pot body along the circumference; Place the upper cover on the convex seat; Then natural air is supplied through the gap between the upper cover and the boss.
