We believe in the quality of our furnace repair* for a year.

How a Furnace Ignitor Works

This part ignites natural gas, which helps heat your home.

Here’s how a furnace ignitor works:

  • Thermostat begins 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 roughly 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 dirty one can cause your HVAC equipment to short cycle.

What Happens When a Furnace Ignitor Breaks Down

Your furnace will tell you there’s something wrong 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 fast flashes or an alternating slow flash as it shares a fault code.

Estimated Repair Cost for Furnace Error Code 270

The cost to fix your furnace hinges on what the issue is with it and the amount of time it takes to repair it.

Before your technician replaces your ignitor, he or she will check:

  • Gas flow
  • Flame sensor current
  • Air filter

Your technician will also make sure the ignitor is legitimately lighting the burner and that there are no interferences or cracked hoses within your equipment.

An ignitor always seems to fail 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
