How a Furnace Ignitor Works
This part ignites natural gas, which helps warm your space.
Here’s how a furnace ignitor works:
- Thermostat launches call for heat.
- Furnace ignitor and blower become triggered.
- Ignitor heats to 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 must be replaced. It can break down sooner if you don’t replace your air filter routinely, since a dirty one can cause your furnace to short cycle.
What Happens When a Furnace Ignitor Stops Working
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 cost to restore your furnace depends 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:
- Gas flow
- Flame sensor current
- Air filter
Your HVAC specialist will also make sure the ignitor is legitimately lighting the burner and that there are no interferences or cracked hoses within your system.
An ignitor always seems to fail when you need it most, prompting an after-hours trip charge.
Here’s the usual costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
