How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

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

A furnace ignitor should last roughly three to five years before it breaks and needs to be changed out. It can stop working sooner if you don’t replace your air filter routinely, since a dirty one can cause your heating system to short cycle.

What Happens When a Furnace Ignitor Stops Working

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 fast flashes or an alternating slow flash as it shares a fault code.

Estimated Repair Cost for Furnace Error Code 270

The bill to fix your furnace rests on what the issue is with it and the amount of time it takes to correct it.

Before your technician replaces your ignitor, he or she will check:

  • Gas flow
  • Flame sensor current
  • Air filter

Your HVAC pro will also make sure the ignitor is truly lighting the burner and that there are no interferences or cracked hoses within your home.

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