How a Furnace Ignitor Works

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

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 approximately three to five years before it fractures and must be changed out. It can wear out sooner if you don’t replace your air filter when needed, since a dirty one can cause your furnace to short cycle.

What Happens When a Furnace Ignitor Breaks Down

Your furnace will show 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 fast flashes or an alternating slow flash as it shares a fault code.
