How a Furnace Ignitor Works
This part ignites natural gas, which helps heat your house.
Here’s how a furnace ignitor works:
- Thermostat begins 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 about three to five years before it breaks and has to be replaced. It can break down sooner if you don’t replace your air filter when needed, since a dusty one can cause your furnace 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 price to restore your furnace rests on what’s wrong with it and how long it takes to remedy it.
Before your technician replaces your ignitor, he or she will investigate:
- Gas flow
- Flame sensor current
- Air filter
Your HVAC pro will also make sure the ignitor is actually lighting the burner and that there are no blockages or cracked hoses within your system.
An ignitor frequently fails when you need it most, resulting in an after-hours trip charge.
Here’s the usual costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
