1, unstable air pressure: the gas stove is burning, but the flame is too weak to reach the stove head, so the air pressure of the gas stove will be very low, and the natural gas stove will not burn as usual and will turn off.
2. Gas thermocouple is broken: This will happen when the gas stove flame is normal. If the thermocouple is broken or damaged, and the intensity signal cannot be provided to the pulser as usual, the pulser of the gas stove will automatically close the electromagnetic valve, and the flameout will be natural.
3. Other situations: There are many other reasons, such as the blockage of the feedback loop of the gas stove and the grounding of the feedback pin, which leads to the signal not reaching the pulser. Of course, the gas stove will also be turned off when the battery is low.

Maintenance method of gas stove:
There are two common faults in the maintenance of electronic gas stoves.
1, the igniter does not generate sparks. Naturally, the piezoelectric ceramic starter of the igniter will not generate sparks, which will make the cooker plate unable to ignite. This failure is mainly due to the automatic switch disconnecting the lead connected to the positive electrode of piezoelectric ceramics, and the automatic switch can be reliably reconnected.
In addition, if the positive electrode of piezoelectric ceramics (i.e. metal round bar) is polluted or corroded, resulting in poor contact, it will also cause ignition difficulties. At this time, you can pull out the metal round bar, wipe off the dirt with fine sandpaper and then insert it.
2, there is a spark but it cannot be ignited. Sometimes the distance between the anode of piezoelectric ceramics and the cathode of the cooker is too far or too close, which will make the spark unable to ignite the gas. The distance should be adjusted to about 4 mm, and the gas nozzle near the igniter is blocked by foreign objects or other foreign objects, which will also cause ignition failure or difficulty. At this time, only the blockage in the nozzle needs to be removed.
