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 activated.
  • 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 breaks and must be subbed out for a new part. It can wear out sooner if you don’t replace your air filter routinely, since a dirty one can cause your furnace to short cycle.

What Happens When a Furnace Ignitor Stops Working

Your furnace will tell you there’s a problem 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.
