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 warms to as hot as 2,500 degrees Fahrenheit and ignites burner gas.

A furnace ignitor should last about three to five years before it cracks and has to be replaced. It can break down sooner if you don’t replace your air filter routinely, since a clogged one can cause your furnace to short cycle.

What Happens When a Furnace Ignitor Fails

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