How a Furnace Ignitor Works
This part ignites natural gas, which helps warm up your space.
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 roughly three to five years before it breaks and needs to be changed out. It can stop working sooner if you don’t replace your air filter when needed, since a dirty one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Fails
Your furnace will tell you there’s an issue 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 short flashes or an alternating slow flash as it shares a fault code.
