How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

  • Thermostat starts call for heat.
  • Furnace ignitor and blower become activated.
  • 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 fractures and must be subbed out for a new part. It can break down sooner if you don’t replace your air filter when needed, since a clogged one can cause your furnace to short cycle.

What Happens When a Furnace Ignitor Fails

Your furnace will tell you there’s a problem 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 price to restore your furnace rests on what’s wrong with it and the time it takes to remedy 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 truly lighting the burner and that there are no obstructions or cracked hoses within your system.

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

Here’s the average costs to replace it:

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