How a Furnace Ignitor Works
This part ignites natural gas, which helps warm up your house.
Here’s how a furnace ignitor works:
- Thermostat launches 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 fractures and needs to be subbed out for a new part. It can stop working sooner if you don’t replace your air filter routinely, since a dusty one can cause your furnace to short cycle.
What Happens When a Furnace Ignitor Fails
Your furnace will show you there’s a problem 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 fast flashes or an alternating slow flash as it shares a fault code.

The bill to fix your furnace rests on what’s wrong with it and how long it takes to correct it.
