How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

  • Thermostat launches call for heat.
  • Furnace ignitor and blower become triggered.
  • Ignitor heats to as hot as 2,500 degrees Fahrenheit and ignites burner gas.

A furnace ignitor should last approximately three to five years before it breaks and must be subbed out for a new part. It can wear out sooner if you don’t replace your air filter when needed, since a dusty one can cause your HVAC equipment to short cycle.

What Happens When a Furnace Ignitor Stops Working

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