It’s winter. It’s cold… and your furnace won’t turn on. While it may sound scary, your furnace not working could be caused by a variety of things. Here’s what to do when your furnace won’t turn on, and when to call in for repairs. 

“My Furnace Won’t Turn On” Checklist

If your furnace won’t turn on, first of all, don’t panic. Here are some troubleshooting steps that you can do yourself. Check these before making a service call. Of course, if you don’t feel 100% comfortable performing any of these checks safely, we’ll be happy to take care of it. 

  1. Power Switch - Make sure it’s turned on.
  2. Circuit Breaker - Even gas and propane furnaces use some electricity.
  3. Pilot Light - It’s a common safety feature for many modern furnaces to not turn on if the pilot light is out. 
  4. Thermostat (including batteries) - Check the settings and test your furnace by turning the heat up.
  5. Vents - Make sure they’re open and clear.
  6. Air Filter - If the air filter is dirty, replace it. 
  7. Drain Pan - Empty it of any water, because your furnace could have an internal float switch.
  8. Oil or Natural Gas Supply - Contact your gas or propane company if you suspect any issues.
