How a Furnace Ignitor Works

This part ignites natural gas, which helps warm your house.

Here’s how a furnace ignitor works:

  • Thermostat begins 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 about three to five years before it cracks and has to be changed out. It can wear out sooner if you don’t replace your air filter routinely, 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 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 quick flashes or an alternating slow flash as it shares a fault code.
