How a Furnace Ignitor Works
This part ignites natural gas, which helps heat your home.
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 approximately three to five years before it fractures and needs to be subbed out for a new part. It can wear out sooner if you don’t replace your air filter when needed, since a clogged one can cause your furnace to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will tell you there’s something wrong with a red flash from its indicator light, which it uses to display 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.
