How a Furnace Ignitor Works

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

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 approximately three to five years before it breaks and must be changed out. It can wear out sooner if you don’t replace your air filter when needed, since a dusty one can cause your HVAC equipment 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 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 rests on the problem with it and how long it takes to repair it.

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

  • Gas flow
  • Flame sensor current
  • Air filter

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

An ignitor frequently fails 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
