How a Furnace Ignitor Works
This part ignites natural gas, which helps warm your home.
Here’s how a furnace ignitor works:
- Thermostat launches call for heat.
- Furnace ignitor and blower become activated.
- 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 breaks and must be subbed out for a new part. It can break down sooner if you don’t replace your air filter regularly, since a dirty one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will show you there’s something wrong 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 fast flashes or an alternating slow flash as it shares a fault code.
