How a Furnace Ignitor Works
This part ignites natural gas, which helps warm up your house.
Here’s how a furnace ignitor works:
- Thermostat starts call for heat.
- Furnace ignitor and blower become energized.
- 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 has to be subbed out for a new part. It can stop working sooner if you don’t replace your air filter regularly, since a clogged one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Fails
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 quick flashes or an alternating slow flash as it shares a fault code.
