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 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 fractures and must be replaced. It can break down sooner if you don’t replace your air filter routinely, since a dirty one can cause your HVAC equipment to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will tell 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 fast flashes or an alternating slow flash as it shares a fault code.
Estimated Repair Cost for Furnace Error Code 270
The bill to restore your furnace depends on what the issue is with it and how long it takes to repair it.
Before your technician replaces your ignitor, he or she will investigate:
- Gas flow
- Flame sensor current
- Air filter
Your HVAC pro will also make sure the ignitor is legitimately lighting the burner and that there are no interferences or cracked hoses within your equipment.
An ignitor often fails when you need it most, prompting an after-hours trip charge.
Here’s the typical costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
