How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

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

A furnace ignitor should last approximately three to five years before it cracks 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 furnace to short cycle.

What Happens When a Furnace Ignitor Breaks Down

Your furnace will show 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 price to restore your furnace depends 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 technician will also make sure the ignitor is truly lighting the burner and that there are no interferences or cracked hoses within your equipment.

An ignitor often fails when you need it most, bringing about an after-hours trip charge.

Here’s the usual costs to replace it:

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