How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

  • Thermostat begins call for heat.
  • Furnace ignitor and blower become energized.
  • Ignitor becomes 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 replaced. It can break down sooner if you don’t replace your air filter routinely, since a dirty one can cause your HVAC equipment to short cycle.

What Happens When a Furnace Ignitor Stops Working

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

  • $200 during normal service hours
  • $300 to $400 after hours
