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 triggered.
  • 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 cracks and needs to be changed out. It can wear out sooner if you don’t replace your air filter regularly, since a dirty one can cause your furnace to short cycle.

What Happens When a Furnace Ignitor Stops Working

Your furnace will show you there’s a problem 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 fast flashes or an alternating slow flash as it shares a fault code.
