Getting cold because you’re seeing error code 270 from your Lennox® furnace?
This means your furnace ignitor can’t activate the flame. After five failed tries, the furnace will halt trying to ignite. It will then switch into Watchguard mode for about an hour for safety reasons.
When your ignitor ceases working, it’s better to rely on our ACE-certified technicians. They’ve gone through important education, so you can rest easy knowing they’ll discover what’s creating the furnace error and will repair it to your satisfaction.
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 heat your home.
Here’s how a furnace ignitor works:
- Thermostat launches call for heat.
- Furnace ignitor and blower become energized.
- Ignitor heats to as hot as 2,500 degrees Fahrenheit and ignites burner gas.
A furnace ignitor should last approximately three to five years before it cracks and has to be subbed out for a new part. It can wear out 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 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 price to fix your furnace hinges on what’s wrong with it and how long it takes to repair it.
Before your technician replaces your ignitor, he or she will look at:
- Gas flow
- Flame sensor current
- Air filter
Your HVAC specialist will also make sure the ignitor is truly lighting the burner and that there are no obstructions or cracked hoses within your system.
An ignitor often fails when you need it most, bringing about an after-hours trip charge.
Here’s the typical costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
