How a Furnace Ignitor Works

This part ignites natural gas, which helps warm your space.

Here’s how a furnace ignitor works:

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

A furnace ignitor should last roughly three to five years before it cracks and must be subbed out for a new part. It can break down 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 Fails

Your furnace will tell you there’s an issue 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 quick flashes or an alternating slow flash as it shares a fault code.
