How a Furnace Ignitor Works
This part ignites natural gas, which helps warm up your house.
Here’s how a furnace ignitor works:
- Thermostat launches call for heat.
- Furnace ignitor and blower become energized.
- 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 breaks and has to be changed out. It can stop working sooner if you don’t replace your air filter routinely, since a clogged one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Breaks Down
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 fast flashes or an alternating slow flash as it shares a fault code.
Estimated Repair Cost for Furnace Error Code 270
The price to restore your furnace rests on the problem with it and how long it takes to correct it.
Before your technician replaces your ignitor, he or she will look at:
- Gas flow
- Flame sensor current
- Air filter
Your HVAC specialist 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 service call.

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