Why does the gas column go out, the fuse or fuse goes out: the reasons for doing it - the column turns off, lights up and goes out

tips Like any technique, the gas column can break down, and one of the most frequent faults is when the unit suddenly goes out during operation. There may be several reasons for this problem, and in order to understand them, one should check in turn each of the nodes that can cause the column to be disconnected.

In piezo-spark-ignition columns, the igniter must be constantly on, as when the hot water tap opens, it must ignite the main burner. Attenuation of the igniter disconnects the column from the gas supply so that gas does not accumulate inside the apparatus.

The pilot can go out if:

• He is littered with debris or dust.
• The airflow was acting on him from the outside.
• Thermocouple is burnt or worn.
• There is no traction in the chimney.
• Thrust sensor failed.
• The solenoid valve has broken.
• No air access.

The most common cause of attenuation of the ignitor is the faulty thermocouple. Its main function is to block the access of gas to the column if the apparatus is unstable. As soon as the ignitor has gone out, the thermocouple detects a shortage of heat and gives a signal to turn off the gas. However, if the thermocouple itself is damaged, it causes damping of the wick.

No less common is the situation when the nozzle of the ignitor receives dust or some debris. Their diameter is very small, so even a little contamination can prevent the ignition of the igniter, as a result of which the thermocouple is not heated enough.

The fact that the igniter has problems and it can go out at any time, suggests the color of its flame. In a normally working wick, the flame will be 90% blue and may include a few red specks, and its tip may be yellow. If the flame of the pilot burner is predominantly yellow or orange, the wick does not work properly, the thermocouple will not heat up sufficiently, causing the burner to go out.

For other possible causes of ignition of the igniter, see the following video.

A sudden shutdown of a column that has only been operating for a couple of minutes is most often caused by an emergency switch on the sensor that detects a gas leak. The device reacts to a dangerous situation by opening the thermocouple, as a result of which the equipment is switched off.

The following video demonstrates how to deal with this problem on your own.

The following problems are caused by this situation:

1. The traction sensor has been triggered, because it has detected that there is no draft in the chimney. This can happen because of the overlap of the ventilation shaft with soot or foreign matter, and also because of the lack of airflow into the room, for example, because of the installation of plastic windows. Another reason for the missing traction is the contamination of the heat exchanger with soot. In addition, the situation is not excluded that the sensor itself failed.
2. The flame sensor has tripped when the main burner has gone out. Although rare, but the burner can go out from a sudden strong gust of wind. But much more often its attenuation is associated with insufficient pressure of water or gas, clogging of mesh filters, and also with the formation of excess scale inside the heat exchanger. Turning off the burner also happens when the diaphragm wears out in the water unit.
3. The gas valve has tripped if the gas pressure in the mains has dropped or the heat exchanger has overheated.
4. Batteries from which the column with automatic ignition are running.

• If you find a problem with the ignition of the igniter( it is smoldering or goes out), the best way is to contact a licensed specialist working with gas equipment. He will check all the nodes that can give such a picture, and also clean your gas column.
• If the column turns on and immediately goes out, do not try to turn on the device again, but close the gas access to the problem device and call a specialist. If the cause of the shutdown is a gas leak, re-inclusion can cause the accumulation of carbon monoxide inside the building, which is not safe for the health of the people staying in the room.
• While the emergency service has not arrived, you can check the traction. To do this, set the match on and light it against the inspection hole on the column panel. If the flame is drawn inward, then the thrust is sufficient. If there is no movement of the flame, disconnect the chimney pipe and repeat the manipulation with the match near the opening of the ventilation shaft. A lighted match will also help you identify problems with the flow of air into the room, if you bring it to the window.
