How a Furnace Ignitor Works
This part ignites natural gas, which helps warm your home.
Here’s how a furnace ignitor works:
- Thermostat begins 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 replaced. It can break down sooner if you don’t replace your air filter routinely, 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 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 quick flashes or an alternating slow flash as it shares a fault code.

The price to mend your furnace depends on the problem with it and the amount of time it takes to remedy it.
