We are confident in the quality of our furnace repair* for a year.

How a Furnace Ignitor Works

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

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 needs to be changed out. It can wear out sooner if you don’t replace your air filter regularly, since a dirty one can cause your HVAC equipment 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 display 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 cost to restore your furnace rests on what the issue is with it and the time it takes to correct 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 truly lighting the burner and that there are no interferences or cracked hoses within your system.

An ignitor frequently fails when you need it most, prompting an after-hours trip charge.

Here’s the average costs to replace it:

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