How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

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

A furnace ignitor should last about three to five years before it cracks and needs to be replaced. It can stop working sooner if you don’t replace your air filter when needed, since a dusty one can cause your heating system to short cycle.

What Happens When a Furnace Ignitor Fails

Your furnace will demonstrate for you there’s something wrong with a red flash from its indicator light, which it uses to display 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 bill to mend your furnace hinges 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 check:

  • Gas flow
  • Flame sensor current
  • Air filter

Your technician will also make sure the ignitor is truly lighting the burner and that there are no interferences or cracked hoses within your equipment.

An ignitor often fails when you need it most, resulting in an after-hours trip charge.

Here’s the average costs to replace it:

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