Simple Tips on How to Troubleshoot Your Furnace

- in Home Appliances

Most of the problems commonly found in heating systems and home furnace can actually be prevented – or solved – through simple but regular maintenance. Even better, you can now have professional furnace and HVAC specialists doing the maintenance and repairs for you. That said, it is still necessary to know some of the basic troubleshooting tips in order to catch potential problems as early as possible. We have just the tips for you in this article.

Check Your Thermostat

One of the very first things you need to do when you begin to notice a drop in heating efficiency inside your house is checking the thermostat. The thermostat is what governs your house’s interior climate. It automatically switches the heating system on and off in order to maintain a certain interior temperature.

To check the thermostat, make sure the device is set on Heat and that the temperature is set above room temperature. You can also set it to maximum heat to see if the system is responding to the inputs properly. If the fan is not running after you set it to maximum….

Check the Power

Check the heating system’s fuse and power source for possible problems. Not having the fan running after you set the thermostat to maximum could mean the system is not getting enough power to operate.

You should also check for burn marks on the circuit board. A fried circuit board could render the entire heating system unusable. Make sure connections and other parts of the electrical system are wired properly.

With most systems, you can bypass the fan control system and turn the fan on manually. This is a good way to check if the power problem is really the cause of your heating system not working.

Furnace’s Pilot Light

Gas furnaces use a pilot light that stays on in order to run properly. The next thing you need to check is the pilot light. Make sure it is properly lit and that the flame touches the tip of your furnace’s thermocouple correctly. Feel the side of the furnace. If the pilot light is lit but the burner wouldn’t turn on, and you feel the side of the furnace rather cold, then you may have a problem with the control board and the limit control for gas flow.

Another reason why the main burner doesn’t switch on is because there is no supply of gas. This may be caused by a lot of things, including possibly catastrophic leaks and faulty flame sensor. It is always best to have a furnace repair specialist continue with the troubleshooting as this stage, especially since you are probably dealing with a more severe problem.

Companies across Canada are offering high quality furnace repair services at affordable rates. You can find them through local directories or by going online, visiting websites of companies such as R.J. Wiley, available at, for more info. Have the entire heating system assessed and get quotes before deciding to move forward with the repair. Don’t forget to consider regular maintenance to prolong the lifespan of your furnace even further.
