1. When the gas stove turns off automatically, first check whether the connecting hose is flat or bent, if it is not; Secondly, check whether the combustion flame is too weak. If it can't reach the burner, the gas pressure is too low. Users who use liquefied gas stoves suggest that they replace the new pressure reducing valve, and coal gas and natural gas can consult the gas supply company.

2. Try replacing the battery, and then see if the flame in the broken side and the middle can burn the probe, because only when it burns the probe can the fire be held. Secondly, it is necessary to ensure the continuous combustion, and the gas stove must ensure the smooth feedback circuit. The feedback mechanism of the gas stove is mostly set in the place where the flame can burn directly. When the flame is normal, the feedback circuit will provide the pulse device with the signal of continuous gas supply, otherwise, the pulse device will close the electromagnetic valve.

3. Nowadays, many gas cookers are equipped with automatic protection devices. Usually, this kind of gas cookers are equipped with an electromagnetic valve at the air inlet pipe. When igniting, the mechanical mechanism will link the electromagnetic valve switch to make the electromagnetic valve work with electricity, so that the gas can be supplied normally. When in use, after the gas cooker is extinguished due to wind, boiler overflow, etc., the ionization probe next to the burning head of the gas cooker can't "pick up" the ionization signal of the flame, so the protection circuit will be started.
