How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

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

A furnace ignitor should last about 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 regularly, since a dirty one can cause your HVAC equipment 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 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.

Estimated Repair Cost for Furnace Error Code 270

The bill to mend your furnace hinges on what’s wrong with it and the amount of time it takes to remedy it.

  • Gas flow
  • Flame sensor current
  • Air filter

Your HVAC pro will also make sure the ignitor is actually lighting the burner and that there are no obstructions or cracked hoses within your system.

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