You probably don’t give your furnace much thought – until it fails. The good news is that many furnace problems are easy to correct. While it’s advisable to hire a professional when your furnace isn’t working properly, there are some issues that you may even be able to fix yourself.
Keep reading to learn about the five most common furnace problems.
Common Furnace Problems
1. Clogged or Dirty Filters
A clogged or dirty filter is one of the most common furnace problems. Clogs and blockages prevent air from circulating properly. This forces the system to work harder and often results in poor heating. To keep your furnace in good working order and to ensure maximum efficiency, replace your filter monthly.
2. Mechanical Wear and Tear
Over the years, your furnace experiences a considerable amount of wear and tear. Furnaces are made up of numerous components, and one stops working properly, the entire unit can breakdown. From overheating to airflow problems and more, mechanical wear and tear can lead to numerous problems with your furnace.
3. Pilot or Ignition Control Issues
Pilot and ignition control are two you’re your furnace’s most important components. If they malfunction, heating your home will be next to impossible.
4. Malfunctioning Thermostat
The thermostat is the device that’s responsible for determining when heat needs to be produced and how much heat is needed. When the thermostat isn’t working properly, heat may not be produced and circulated throughout your home. A malfunctioning thermostat could also cause your furnace to produce too much heat.
5. Lack of Maintenance
Chances are, you spent thousands on your furnace. Wouldn’t it make sense to spend some money to properly maintain it? Unfortunately, lack of maintenance is one of the most common causes of furnace problems. Without regular maintenance and inspections, your furnace is prone to breakdowns and poor performance. You could also see increased energy costs as the result of failing to maintain your furnace.

Did your furnace give out? It’s understandable given all of the overtime work it’s been putting in. But before assuming the worst and calling in a professional, learn some basic furnace troubleshooting tips to get your heat running again.
Breaker Box – Check to see if your furnace threw the breaker switch. If you don’t have your breaker panel labeled, now is a good time to do so. After locating the correct breaker switch, simply flip the switch all the way to the “off” position (opposite direction of all the other switches) and then flip it back on (same direction as all the other switches).
Furnace Filter – If your power is on, you should check your furnace’s air filter. Sometimes, your furnace will actually shut itself off if the filter is dirty and clogged enough. This is done as a precautionary measure since an overloaded heat exchanger can be dangerous and lead to costly repairs.
If you don’t remember the last time you replaced the filter, then it is probably due for one. To make sure that you remember to check and/or change the furnace filter every 30-90 days, you should set a reminder on your phone or calendar for the first of every month to check the filter.
Blower Panel – Like with the furnace filter, sometimes a furnace won’t turn on as a precautionary measure if the blower panel is ajar. This prevents the blower from turning on while someone is working on the furnace. If your furnace won’t start, make sure the door that houses your blower motor is fully closed.
Thermostat – The next thing you want to check is your thermostat. Make sure that it is set to “heat” and that the thermostat is set above the room temperature. Also, check to see if you need to change the batteries. Here is a good video for learning how to change your thermostat’s batteries if you have never done so before:
Gas Valve & Pilot Light – If the previous steps did not solve your problem, the issue may be with your gas valve or pilot light. The gas valve may have inadvertently been closed or forgotten to be turned back on when someone was working on the furnace. If the gas valve, your furnace won’t have the fuel necessary to run.
To locate your gas valve, trace the gas line to your furnace until you see a handle on the pipe. If the handle is perpendicular, turn it until it is parallel with the pipe. Sometimes there will be a separate gas valve located on or around your furnace. Look around to ensure the gas is “on.”
If you have an older furnace, you should check the pilot light to see if it is lit. If the gas is on, but still no flame, you will want to turn the gas “off” again in order to relight the pilot light. Once the gas is off and all the fumes have disappeared, now it is safe to light the pilot light. Make sure you double check your model’s specific manufacturer instructions, but it is safe to say that you either have an ignitor button or will have to manually light it with a long match or lighter. For most furnaces, this how-to video should do the trick:
