How a Furnace Ignitor Works
This part ignites natural gas, which helps warm your space.
Here’s how a furnace ignitor works:
- Thermostat starts call for heat.
- Furnace ignitor and blower become triggered.
- Ignitor becomes 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 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 HVAC equipment to short cycle.
What Happens When a Furnace Ignitor Breaks Down
Your furnace will tell 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.
