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 activated.
  • Ignitor becomes as hot as 2,500 degrees Fahrenheit and ignites burner gas.

A furnace ignitor should last about three to five years before it breaks and has to be subbed out for a new part. It can stop working sooner if you don’t replace your air filter regularly, since a dusty one can cause your furnace to short cycle.

What Happens When a Furnace Ignitor Stops Working

Your furnace will demonstrate for 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 mend your furnace depends on what the issue is with it and how long it takes to remedy it.

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

  • Gas flow
  • Flame sensor current
  • Air filter

Your HVAC specialist will also make sure the ignitor is actually lighting the burner and that there are no blockages or cracked hoses within your equipment.

An ignitor always seems to fail when you need it most, prompting an after-hours trip charge.

Here’s the typical costs to replace it:

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