Turned the natural gas safety valve, and suddenly there was no gas. What happened?

There is something wrong with starting the ignition! ?

First of all, ensure sufficient ignition power and good connection.

Then, observe whether the microswitch lever can be fully opened every time it is turned on (if the ignition cannot be turned on, the diaphragm of the water-gas linkage valve will be replaced due to aging or damage).

If there is nothing wrong with the first two, it is the micro switch or the controller itself.

Check and eliminate the above one by one! I'll teach you a way to try:

Now use the machine fire knob to adjust the minimum water volume knob to the minimum (that is, it is not easy to turn off the fire when the water temperature is high and cold water is added). If you feel very hot, turn down the gas switch on the inlet pipe of the water heater gradually to reduce the combustion power of the machine and make the outlet water reach the appropriate water temperature. This method is convenient and will not waste more gasoline. Give it a try!

Generally speaking, the pulse igniter is broken and can be removed and replaced. They are sold in electronic parts stores or home appliance repair shops, and the average price is 8 yuan, 16 yuan is better.

The gas water heater can't catch fire: the system is divided into four parts, gas, circuit, waterway and machinery; Let's talk about your anger first. A gas water heater can only be used for one gas source, and bottled gas water heaters can only use bottled liquefied gas, and cannot be installed on pipeline natural gas, otherwise it will not catch fire or the temperature is not enough.

You yourself have ruled out the external electricity and gas factors, and you can be sure that there is something wrong with the water heater. The sound of snapping ignition indicates that the power part of the water heater is working. If there is no gas coming up, pay attention to the sound of the solenoid valve inhaling. If there is, it can be ventilated. If there is no sound of valve inhalation, the gas will definitely not come up.
