Repairing a Gas Furnace - Common Problems You Can Handle On Your Own

By Anita Teran


A gas furnace is a very important appliance in your home because it keeps it warm without taking up too much energy. It is a very simple appliance consisting of a gas burner, a stainless steel heat exchanger, a blower and an air filter. It usually gives you trouble free operation for a long time as long as you take care of it well and handle small problems as and when they occur. In addition, furnaces that don't perform well can also be a source of carbon monoxide poisoning in your home. Luckily, it is very easy to troubleshoot these problems and you will get excellent performance out of your furnace for as long as possible.

One of the most common problems is that the gas furnace doesn't produce sufficient amounts of heat even if you set the thermostat to high. The most likely reason is that the air filter or the gas burners are dirty. Another problem that is caused by having very dirty filters is that the furnace switches does not work continuously. Instead, it will switch off and on in the midst of operation very frequently. Always check to see if your filters are too dirty before you explore other possible causes such as faulty thermostats. In fact, the filter of a gas furnace has to be replaced or cleaned every three months or so depending on how bad they are.

You might even face a situation when your gas furnace does not produce any heat at all. The most common reason for this is a thermostat that is set too low. Less likely reasons are that the thermostat is not working or even that the circuit breaker is tripped. You can easily set the thermostat or the circuit breaker on your own by checking the instruction manual on the furnace, if required. Sometimes, the problem might even be a simple one that the gas control valve is closed due to some reason. You just have to open it in order to let the propane or natural gas do its job. #72579797-apprentice-MP

If your gas furnace is too noisy and causes a lot of disturbance at your home then you have to check the blower belt to see whether it is fitted properly and has the right tension. If it slips even slightly it will cause a lot of noise. You will need to replace the belt just in case it has become frayed due to long use. Another possible cause for the sound is that the blower motor has lost all its lubrication. You can easily address this problem with the help of oil.

You will save quite a bit of money if you handle these problems on your own. Not only will you save on repair technicians' fees but your gas furnace will also work much better than usual. It will work perfectly keeping your home at the right temperature, and will not cost you a huge packet while doing so. However, you should also get it professionally serviced annually.
