3 Simple Issues You Can Have With Your Home's Furnace

Posted on

If you are a homeowner that uses a furnace to heat your home, you'll likely run into a problem with the furnace at some point. Here are a few simple problems, as well as what you can do about them and when it's time to call local heating contractors.  

Airflow Problems

Is the furnace igniting and the blower fan running, but you do not have any heat coming out of your vents? This indicates that there is an airflow problem. Start by looking at the filter, which is one of the main things that could be restricting airflow. Try swapping out the filter with a new one, and if that doesn't do the trick, call a professional.

Furnace Not Turning On

Always start with the simplest problems when the furnace is not turning on. Start with inspecting the thermostat and replacing the batteries. If the batteries are fresh, make sure that everything is in the correct mode. Clear out any temperature schedule settings, put the thermostat in heat mode, and turn the fan on auto mode. The next thing to check is the circuit breaker, which may need to be reset. There is also going to be a power switch next to your furnace that should be in the on position.

Another thing to check is whether the furnace cover is completely closed. There may be a safety switch that is preventing the furnace from turning on because a cover is not completely on the unit. Finally, check the gas line going to your furnace if it is gas-powered, and make sure that the valve has not been closed by accident. 

Warning Light Flashing 

You may have a warning light on the side of the furnace that is indicating that something is wrong. The best way to tell what this light means is to get out the manual that came with your furnace or to find it online. There will be a series of light flashes that indicate a code, which should tell you the exact problem the furnace is trying to tell you about. This can help relay the proper information to an HVAC contractor to fix the furnace for you.

Have an issue that is not covered by one of these three simple problems? Then it's time to reach out to a professional for help. They'll be able to diagnose the problem and let you know what the problem is.
