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 triggered.
- Ignitor warms to as hot as 2,500 degrees Fahrenheit and ignites burner gas.
A furnace ignitor should last approximately three to five years before it cracks and needs to be changed out. It can wear out sooner if you don’t replace your air filter when needed, since a dirty one can cause your furnace to short cycle.
What Happens When a Furnace Ignitor Fails
Your furnace will show you there’s something wrong 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 cost to fix your furnace rests 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 investigate:
- Gas flow

Your HVAC pro will also make sure the ignitor is legitimately lighting the burner and that there are no obstructions or cracked hoses within your system.
