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 heats to 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 stop working sooner if you don’t replace your air filter when needed, since a clogged one can cause your furnace to short cycle.

What Happens When a Furnace Ignitor Fails

Your furnace will show you there’s an issue 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 fast 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 the issue is with it and the amount of time it takes to repair 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.

  • $200 during normal service hours
