How a Furnace Ignitor Works
This part ignites natural gas, which helps heat your house.
Here’s how a furnace ignitor works:
- Thermostat starts call for heat.
- Furnace ignitor and blower become energized.
- Ignitor becomes 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 needs to be changed out. It can stop working sooner if you don’t replace your air filter regularly, since a dusty one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Breaks Down
Your furnace will demonstrate for 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 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 hinges on what the issue is 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 technician will also make sure the ignitor is truly lighting the burner and that there are no blockages or cracked hoses within your home.
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
