How a Furnace Ignitor Works
This part ignites natural gas, which helps heat your home.
Here’s how a furnace ignitor works:
- Thermostat launches call for heat.
- Furnace ignitor and blower become energized.
- Ignitor warms to as hot as 2,500 degrees Fahrenheit and ignites burner gas.
A furnace ignitor should last approximately three to five years before it breaks and has to be changed out. It can wear out sooner if you don’t replace your air filter regularly, since a dirty one can cause your HVAC equipment to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will show you there’s a problem 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 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 hinges on the problem with it and how long 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 interferences or cracked hoses within your equipment.
An ignitor always seems to fail when you need it most, resulting in an after-hours repair call.
Here’s the average costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
