How a Furnace Ignitor Works
This part ignites natural gas, which helps warm up your space.
Here’s how a furnace ignitor works:
- Thermostat begins call for heat.
- Furnace ignitor and blower become activated.
- Ignitor becomes as hot as 2,500 degrees Fahrenheit and ignites burner gas.
A furnace ignitor should last about three to five years before it fractures and has to be subbed out for a new part. It can break down sooner if you don’t replace your air filter when needed, since a dusty 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 display error codes. It has this red light to flash code, much like Morse code.
You might see short 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’s wrong with it and the time it takes to correct it.
Before your technician replaces your ignitor, he or she will check:
- Gas flow
- Flame sensor current
- Air filter
Your technician will also make sure the ignitor is actually lighting the burner and that there are no blockages or cracked hoses within your equipment.
