How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

  • Thermostat launches 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 must be changed out. It can break down sooner if you don’t replace your air filter when needed, since a dusty one can cause your heating system 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 short 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 rests on what the issue is with it and the amount of 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 obstructions or cracked hoses within your system.

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

Here’s the typical costs to replace it:

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