How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

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

A furnace ignitor should last about three to five years before it fractures and has to be changed out. It can wear out sooner if you don’t replace your air filter routinely, since a clogged one can cause your heating system to short cycle.

What Happens When a Furnace Ignitor Stops Working

Your furnace will demonstrate for 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 cost to restore your furnace depends on what the issue is with it and the 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 pro will also make sure the ignitor is legitimately lighting the burner and that there are no obstructions or cracked hoses within your equipment.

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