Why isn't my furnace working?

It's a question we never want to ask ourselves, but the time comes for all of us. If your furnace isn't turning on, it can be a frustrating experience, and that's putting it lightly. You may not know what is wrong, or who to call for help. In this blog post, we will discuss some common reasons why your furnace might stop working.

Check the Pilot Light

One common reason why your furnace may not be turning on is because the pilot light is out. If this is the case, you will need to relight the pilot light. This can usually be done by following the instructions in your furnace's owner's manual. While this might be intimidating, it's a quick and easy fix.

You've Turned the Thermostat Off

Another common reason for a furnace not to turn on is because the thermostat is set to "off." Be sure to check your thermostat and make sure it is turned to "on." If it is already on, try setting it to a higher temperature to see if that kicks the furnace on.

The Power Source Is Disconnected

If your furnace still isn't turning on, it could be because the power source is disconnected. Check to make sure that the furnace is plugged in and that the circuit breaker has not been tripped. If everything looks normal, you may need to call an electrician to take a look at the wiring.

Keep in mind, the best way to ensure your furnace is at its best is through regular servicing. Read What Is the Ideal Schedule for Servicing for a Furnace?

What if It Still Isn't Working?

These are just a few common reasons why your furnace might not be turning on. However, there are many components to a furnace and that means there are many places where things can go wrong. If you have checked all of the above and your furnace still isn't working, it's time to call in a professional. A qualified technician will be able to diagnose the problem and get your furnace up and running again in no time.
