How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

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

A furnace ignitor should last approximately three to five years before it cracks and has to be subbed out for a new part. It can break down sooner if you don’t replace your air filter routinely, since a dusty one can cause your furnace to short cycle.

What Happens When a Furnace Ignitor Fails

Your furnace will demonstrate for you there’s an issue 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 fast flashes or an alternating slow flash as it shares a fault code.

Estimated Repair Cost for Furnace Error Code 270

The price to mend your furnace depends on what’s wrong with it and the amount of time it takes to repair it.

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

  • Gas flow
  • Flame sensor current

  • $200 during normal service hours
