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 energized.
- Ignitor heats 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 has to be changed out. It can stop working sooner if you don’t replace your air filter when needed, since a clogged one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will demonstrate for you there’s something wrong 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 short flashes or an alternating slow flash as it shares a fault code.
