How a Furnace Ignitor Works
This part ignites natural gas, which helps heat your space.
Here’s how a furnace ignitor works:
- Thermostat starts 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 cracks and needs 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 clogged one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will tell 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 cost to restore your furnace hinges on what’s wrong with it and the amount of 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 HVAC specialist will also make sure the ignitor is actually 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, bringing about an after-hours trip charge.
Here’s the average costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
