Though troubleshooting a gas furnace may seem like a daunting task to many people, it is not hard work in real sense. You just need to establish the parts of the gas furnace that are having defects and find the proper way to fix them. Do It Yourself (DIY) fixes should only be done to those problems that you are absolutely sure that you can handle?
When trying to fix your gas furnace, you will first of all need to check it whether it is working or not. Find out whether it is in a condition that can be fixed with repairs or it will be costly to do that. Some gas furnaces may be damaged beyond repair and therefore they will be better replaced than repaired. If for instance you find that the motor of the gas furnace is not working, you will need to replace it or hire a technician to repair it for you. Attempting Do It Yourself repairs in such a case may make the condition of the furnace worse.
If the gas furnace is having heat production problems, you will need to check the pump and its heat control. If the pump is having problems, you can easily replace it on your own. Air control of the gas furnace can be made effective by cleaning the filters. The reasons why the pump may fail are many, some which may not require you to spend a lot of money to have it fixed. You can save money by doing simple repairs on the furnace and also making sure that it is properly maintained.
Sometimes the gas furnace may fail to work as a result of blown fuses or tripped circuit breakers. To fix such problems, you will need to check all the circuit breakers that are around or near the furnace and restore them. If you don’t know how to go about this, be sure to seek professional help to avoid causing more problems to the gas furnace.
Motor overload and pilot light out can be simple fixes, but you also need to be absolutely sure of the repair procedures you are using to avoid major problems in the future. If your gas furnace has a motor overload, you can just wait for 30 minutes after the overload occurred and then press the reset button. If resetting once does not work, you will need to do it several times. Fixing a pilot light that is off will require you to simply relight it.
The combustion fan may fail to work completely. Troubleshooting this issue will be done by checking the voltages and the circuit boards. Blown-out fuses could alter the voltages and cause the fan to stop working, so you will need to check them and replace them. A malfunctioning circuit board could also cause you to have both low and high voltages that could cause the fan to malfunction.
A very important thing to remember when troubleshooting a gas furnace is to never hesitate to seek professional help if you cannot diagnose the problem by simply looking over the furnace. For more articles on gas furnaces, be sure to stay up to date with my site.
