How to fix a column?

The cost of repair work is now rolls over. And this is almost everything: in the repair of furniture, plumbing, gas water heaters and stoves. Today we will talk how to fix a gas column with your own hands.

We begin repair

The very first thing you should do is turn off the flow of gas to the column and water. That is, before starting to repair the gas column, it is mandatory (!) To turn off the gas and water supply valves. In order to remove the gas column frame, it is necessary to unscrew the two screws (usually they are located inside the column). The left knob for regulating gas supply to the column and the ignition knob are not removed. You can also not remove the right gas control knob. See for yourself, different columns - different modifications, but the principle is the same. We describe only the most frequent cases of breakage of gas columns.

Not ignited

Such a problem is encountered in gas columns with automation, that is, in these columns there is a protection system. In your column, the gas in the pilot must always be lit and this should not depend on the position of the knobs, the water supply and the valves.Typically, such a protection system consists of a fuse, a valve and a thermocouple.

In order to repair the protection automation, it is necessary to understand well what it consists of. Thermocouple - welded in one or two wiring from different metals. Designed to power the valve in the column. Usually do not break. Look carefully, perhaps these two welded wiring broke off from the point of attachment to the valve. If you have such a breakdown, it is necessary to change the thermostat, because this very junction generates a current and not repair it manually. This is one of the options that will help you understand how to fix the column.

The solenoid valve in the gas column is a coil of copper (wire), inside it there is a metal cylinder, it is mechanically tied to the gas transmission stop valve in the column wick. If the thermocouple heats up, it gives off electricity, which, going through a copper coil, produces a magnetic field, this field pulls in the solenoid (it is connected to this valve, so the valve shifts and the gas begins to penetrate into the column). And if the gas is off, then the thermocouple cools down and there is no current, the solenoid comes to its initial position and the gas is no longer supplied.So if your wick is extinguished by a draft or something else, then when you open the water, the gas will not light up.

Thermal fuse - bimetallic plate. When it is heated (in the installation zone of the thermal fuse) at 90 degrees, it bends, so that the power circuit is broken (the power supply of the selenoid). In additions, the thermal fuse is connected via terminals. But it happens that this element of the column fails, then it is worth replacing it, otherwise the column will go off permanently.

Checking the thermal fuse

It is worth checking if your column has good traction and good air flow. If you have sealed your dwelling so much (the windows are closed tightly, the hood is working, the door is closed), then there will be no traction and the column will overheat. This is what the thermal cutter is involved in - it doesn’t allow us to suffocate with carbon monoxide.

In order to check it, do so: remove the terminals from it and short-circuit them with each other with absolutely any object. The object must be metal (spoon, needle, clip). If after that the column serves properly, then the problem was in this cause.

Goes off during work

Perhaps no traction.We have previously written about this. Still, it is worth opening the door and the window in the kitchen. If after twenty minutes the column is working properly, then you have found the cause of the malfunction. Also, the thrust may be absent due to the fact that the column ventilation is clogged with soot or if there are foreign objects in it. By eliminating this damage, you take out the vent pipe, attach a sheet to the open end, if it holds, then there is a draft, you can also bring a lit speech or a lighter. If there is no traction, then clean the channel. We hope that a few of our lessons on the topic: how to fix a gas water heater will help you to repair your equipment.
