How a Furnace Ignitor Works

This part ignites natural gas, which helps warm up your home.

Here’s how a furnace ignitor works:

  • Thermostat begins call for heat.
  • Furnace ignitor and blower become energized.
  • Ignitor becomes 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 must be changed out. It can break down sooner if you don’t replace your air filter routinely, since a clogged one can cause your HVAC equipment to short cycle.

What Happens When a Furnace Ignitor Stops Working

Your furnace will tell you there’s something wrong with a red flash from its indicator light, which it uses to communicate error codes. It has this red light to flash code, much like Morse code.

You might see short 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 rests on what the issue is with it and the amount of time it takes to remedy it.

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

  • 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 blockages or cracked hoses within your equipment.

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

Here’s the typical costs to replace it:

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