How a Furnace Ignitor Works

This part ignites natural gas, which helps heat your home.

Here’s how a furnace ignitor works:

  • Thermostat starts call for heat.
  • Furnace ignitor and blower become activated.
  • 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 subbed out for a new part. It can break down sooner if you don’t replace your air filter routinely, since a dusty one can cause your HVAC equipment to short cycle.

What Happens When a Furnace Ignitor Stops Working

Your furnace will show you there’s an issue with a red flash from its indicator light, which it uses to communicate 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.
