How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

  • Thermostat starts call for heat.
  • Furnace ignitor and blower become activated.
  • Ignitor becomes 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 needs to be replaced. It can break down sooner if you don’t replace your air filter when needed, since a dusty one can cause your furnace to short cycle.

What Happens When a Furnace Ignitor Stops Working

Your furnace will demonstrate for 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 fast flashes or an alternating slow flash as it shares a fault code.

Estimated Repair Cost for Furnace Error Code 270

The bill to restore your furnace hinges on what’s wrong 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 pro will also make sure the ignitor is actually lighting the burner and that there are no blockages or cracked hoses within your equipment.

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

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