How a Furnace Ignitor Works
This part ignites natural gas, which helps warm up your house.
Here’s how a furnace ignitor works:
- Thermostat starts call for heat.
- Furnace ignitor and blower become energized.
- 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 cracks and must be changed out. 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 Fails
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.
Estimated Repair Cost for Furnace Error Code 270
The bill to mend your furnace rests on what the issue is with it and how long it takes to correct it.
Before your technician replaces your ignitor, he or she will investigate:
