We are confident in the quality of our furnace repair* for a year.
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 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 stop working sooner if you don’t replace your air filter regularly, since a dirty one can cause your furnace to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will tell 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 short flashes or an alternating slow flash as it shares a fault code.
Estimated Repair Cost for Furnace Error Code 270
The cost to fix your furnace hinges on what the issue is with it and the amount of time 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 pro will also make sure the ignitor is truly lighting the burner and that there are no obstructions or cracked hoses within your home.
An ignitor often fails when you need it most, resulting in an after-hours trip charge.
Here’s the usual costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
