How a Furnace Ignitor Works

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

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 about three to five years before it cracks and must be replaced. It can stop working sooner if you don’t replace your air filter when needed, since a clogged one can cause your heating system to short cycle.

What Happens When a Furnace Ignitor Stops Working

Your furnace will tell you there’s a problem 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 fix your furnace hinges on what’s wrong with it and the amount of time it takes to correct 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 legitimately lighting the burner and that there are no interferences or cracked hoses within your equipment.

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

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