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 activated.
  • Ignitor becomes 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 has to be changed out. It can wear out sooner if you don’t replace your air filter regularly, since a clogged one can cause your furnace to short cycle.

What Happens When a Furnace Ignitor Stops Working

Your furnace will show you there’s an issue with a red flash from its indicator light, which it uses to communicate 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 fix your furnace depends on what’s wrong with it and how long it takes to correct it.

Before your technician replaces your ignitor, he or she will look at:

  • Gas flow
  • Flame sensor current
  • Air filter

Your HVAC pro will also make sure the ignitor is legitimately lighting the burner and that there are no blockages or cracked hoses within your home.

An ignitor always seems to fail when you need it most, resulting in an after-hours service call.

Here’s the usual costs to replace it:

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