How a Furnace Ignitor Works
This part ignites natural gas, which helps warm up your home.
Here’s how a furnace ignitor works:
- Thermostat begins call for heat.
- Furnace ignitor and blower become activated.
- Ignitor heats to as hot as 2,500 degrees Fahrenheit and ignites burner gas.
A furnace ignitor should last about three to five years before it fractures and must be subbed out for a new part. It can break down 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 an issue with a red flash from its indicator light, which it uses to exhibit 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 bill to restore your furnace rests on what the issue is with it and the time 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 truly lighting the burner and that there are no obstructions or cracked hoses within your equipment.
An ignitor always seems to fail when you need it most, bringing about an after-hours trip charge.
Here’s the typical costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
