How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

  • Thermostat launches 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 breaks and needs to be replaced. It can wear out 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 Stops Working

Your furnace will show you there’s a problem with a red flash from its indicator light, which it uses to exhibit 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 mend your furnace depends on the problem with it and the amount of time it takes to remedy it.

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

  • Gas flow
  • Flame sensor current

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