How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

  • Thermostat begins call for heat.
  • Furnace ignitor and blower become triggered.
  • 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 cracks and needs to be changed out. It can break down sooner if you don’t replace your air filter when needed, since a dirty one can cause your heating system to short cycle.

What Happens When a Furnace Ignitor Fails

Your furnace will tell you there’s an issue 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 cost to mend your furnace depends on what the issue is with it and how long it takes to correct it.

Before your technician replaces your ignitor, he or she will look at:

  • Gas flow
  • Flame sensor current
  • Air filter

Your HVAC pro will also make sure the ignitor is legitimately 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, resulting in an after-hours trip charge.

Here’s the typical costs to replace it:

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