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 breaks and must be changed out. It can stop working sooner if you don’t replace your air filter routinely, since a clogged one can cause your heating system to short cycle.

What Happens When a Furnace Ignitor Breaks Down

Your furnace will tell 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 quick flashes or an alternating slow flash as it shares a fault code.

Estimated Repair Cost for Furnace Error Code 270

The cost to mend your furnace rests on what’s wrong with it and the amount of time 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 truly lighting the burner and that there are no blockages or cracked hoses within your home.

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

Here’s the usual costs to replace it:

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