1. The solenoid valve is not reopened
For pre-paid gas meters, they have a solenoid valve that can automatically cut off the gas, and this solenoid valve will automatically close after the gas meter is unpaid, cutting off the gas supply. When we give the top up again, it does not automatically open the solenoid valve. The reason for this design is to prevent accidental leakage of gas, such as the valve of the subsequent equipment is not closed, and we do not care about it after charging, which may lead to the leakage of gas and cause accidents. Therefore, many gas meters need to manually restart the gas meter after recharge, and it is still out of gas without restarting.
Solution: According to different gas meters, there are different methods, which can be roughly divided into two categories, one is to long press the button on the gas meter after recharge, when you hear the sound of the valve opening, the LCD screen displays the valve, even if it is opened. The other type is the gas meter without a button, you need to re-put the recharge card of the gas meter, insert the gas meter, and wait for a few seconds, hear the valve open, you can.
2, the gas meter battery is insufficient
At present, many gas meters are still powered by dry batteries, and when the battery is insufficient, the solenoid valve of the gas meter cannot be automatically opened. Although sometimes the gas meter displays normally, the solenoid valve still cannot be opened. The main reason is that the battery power is insufficient, which can only support the information display of the gas meter, but cannot support the rotation of the solenoid valve motor and open the solenoid valve. Even if it can be used normally when there is gas before, it does not mean that after closing, it can also support the re-opening of the solenoid valve. In this way, there will be a problem that the gas can not be used after the arrears are recharged.
Solution: In the case of the above, replacing the battery of the gas meter can solve the problem. The gas meter generally uses four No. 5 batteries, we do not need to care whether it is displayed normally, take out the old battery, replace the new battery and then restart the gas meter can solve the problem.
Check whether the battery is dead, or improper operation or error. Check whether the gas stove is faulty
If the gas is paid, or there is no gas, we need to restart the gas meter, or replace the battery to use it.
