How a Furnace Ignitor Works
This part ignites natural gas, which helps warm your home.
Here’s how a furnace ignitor works:
- Thermostat begins call for heat.
- Furnace ignitor and blower become activated.
- 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 cracks and has to be replaced. It can stop working sooner if you don’t replace your air filter routinely, 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 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 depends on what’s wrong with it and how long it takes to repair 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 obstructions or cracked hoses within your home.
An ignitor always seems to fail 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
