How a Furnace Ignitor Works
This part ignites natural gas, which helps heat your home.
Here’s how a furnace ignitor works:
- Thermostat starts 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 breaks and must be subbed out for a new part. It can wear out sooner if you don’t replace your air filter routinely, since a dusty one can cause your HVAC equipment to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will tell 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 fast flashes or an alternating slow flash as it shares a fault code.
Estimated Repair Cost for Furnace Error Code 270
The price to mend your furnace rests on what the issue is with it and the time 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 pro will also make sure the ignitor is truly lighting the burner and that there are no obstructions or cracked hoses within your system.
An ignitor often fails when you need it most, bringing about an after-hours service call.
Here’s the usual costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
