There is not actually a lot to go wrong with contemporary gas furnaces, but each mechanical device can fail and the central heating system is one of them. The problem is though, that hundreds of millions of households all over the world have come to rely on their central heating unit.
In general, people are not advised to meddle with things that they know nothing about, particularly if it refers to something that could become a fire hazard, but this article is about safe gas furnace repairs, that you can undertake yourself.
Some of these tips might stand you in good stead if the gas furnace in your home central heating system gives up the ghost. These pointers could save you cold nights and high call-out fees.
The more that you get intimate with your central heating system, the more easily you will identify issues that arise, because in general, home heating units have sporadic issues and recurring problems.
Does your heating system keep turning itself on and off at inappropriate times? This almost certainly has something to do with the thermostat. The old way of dealing with thermostats was to tinker with them, but no one does that anymore, they only replace them. You may as well do the same.

If your central heating system keeps closing down, this is also probably a problem with the thermostat, as long as there is fuel in the tank. The tactic is the same. Look at the disk inside the thermostat and read any writing on it. Usually, if you bias it one way or the other, it will correct the problem.
A really simple one is the pilot light. If your set-up is not working, just check that the pilot light is burning. The pilot light serves as the ignition for a heat cycle, so if there is not one there, there will be no heat cycle or heating.
The pilot light can be blown out or merely go out because of a temporary shortage of fuel, after which it will have to be re-ignited.
If your whole heating system seems to be working normally, but there is no heat coming through the vents, it is probably the blower. Check the fan belt and either tighten the tension or replace it. This is an easy job, which, having done once, you can do in your sleep.
The foremost thing concerning any home appliance is not to automatically reach for the phone book if things go wrong. That is exactly what the want you to do. They would like you to think that items are too difficult unless you have studied them, whereas in fact, most engineers only replace parts – very little is fixed or taken apart any more.
