How a Furnace Ignitor Works

This part ignites natural gas, which helps warm up your house.

Here’s how a furnace ignitor works:

  • Thermostat launches call for heat.
  • Furnace ignitor and blower become energized.
  • Ignitor warms to as hot as 2,500 degrees Fahrenheit and ignites burner gas.

A furnace ignitor should last approximately three to five years before it breaks and has to be changed out. It can stop working sooner if you don’t replace your air filter routinely, since a clogged one can cause your heating system to short cycle.

What Happens When a Furnace Ignitor Breaks Down

Your furnace will show you there’s something wrong with a red flash from its indicator light, which it uses to display error codes. It has this red light to flash code, much like Morse code.

You might see fast flashes or an alternating slow flash as it shares a fault code.
