Help! My Furnace Won’t Start Up

Temperatures have begun to decline, signaling that the start of winter is a lot closer than it seems. Soon enough, you’ll be turning on your heater to keep your home comfortable, if you haven’t already. Hopefully if you have, you didn’t have any problems.

But what happens if you go to turn your furnace on and it doesn’t start up? What could be the cause of this trouble? Read on to learn why furnaces may fail to turn on.

Miscalibrated Thermostat

Sometimes the problem with a furnace isn’t with the furnace at all—it’s the thermostat. This component is the brain of your entire HVAC system. Even the smallest mishap can lead to the improper reading of your home’s temperature, preventing the thermostat from turning your furnace on. Your thermostat could also be to blame if it has old, corroded, or broken wiring which has lost its connection to the heating system.

The Electronic Igniter Needs Replacement

Most homeowners don’t realize that even modern gas-powered furnaces require electricity to run. And the most important component in your furnace related to this is the electronic igniter. This component, which should be replaced every few years, activates the burners. A failing igniter can often be caught during your maintenance appointment, but this is not always the case—sometimes it can fail even if it appears healthy to your HVAC technician.

You Have a Dirty or Rusted Burner

The burner in your gas-fueled furnace is where the gas jets ignite in order to provide heat. But if the burner develops a layer of dirt or grime on it, or if rust flakes find their way inside, then it can’t draw in sufficient oxygen in order to light. You’ll want a professional technician to remove the burner and thoroughly clean that along with the rest of your furnace.
