When your ignitor ceases working, it’s better to rely on our ACE-certified technicians. They’ve gone through detailed education, so you can rest easy knowing they’ll determine what’s creating the furnace error and will fix it to your standards.

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

How a Furnace Ignitor Works

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

Here’s how a furnace ignitor works:

  • Thermostat begins call for heat.
  • Furnace ignitor and blower become triggered.
  • 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 replaced. It can wear out sooner if you don’t replace your air filter regularly, since a clogged 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 display 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 bill to fix your furnace rests on the problem with it and the amount of time it takes to remedy it.

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

  • 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 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 typical costs to replace it:

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