How a Furnace Ignitor Works
This part ignites natural gas, which helps heat your space.
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 about 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 when needed, since a dirty one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Breaks Down
Your furnace will show you there’s an issue 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.
Estimated Repair Cost for Furnace Error Code 270
The price to mend your furnace rests on what the issue is with it and the time it takes to repair it.
Before your technician replaces your ignitor, he or she will check:
- Gas flow
- Flame sensor current
