How a Furnace Ignitor Works

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

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 roughly three to five years before it cracks and must be subbed out for a new part. It can wear out sooner if you don’t replace your air filter when needed, since a clogged one can cause your furnace to short cycle.

What Happens When a Furnace Ignitor Breaks Down

Your furnace will show you there’s an issue with a red flash from its indicator light, which it uses to exhibit 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.
