How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

  • Thermostat starts 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 cracks and must be subbed out for a new part. It can stop working sooner if you don’t replace your air filter when needed, since a dirty one can cause your heating system to short cycle.

What Happens When a Furnace Ignitor Stops Working

Your furnace will demonstrate for 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 short flashes or an alternating slow flash as it shares a fault code.
