Getting cold because you’re seeing error code 270 from your Lennox® furnace?
This means your furnace ignitor can’t start the flame. After five failed attempts, the furnace will quit trying to ignite. It will then switch into Watchguard mode for about an hour for your safety.
When your ignitor ceases working, it’s best to count on our ACE-certified technicians. They’ve gone through important training, so you can rest easy knowing they’ll find out what’s generating the furnace error and will mend it to your standards.
We trust 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 energized.
- Ignitor warms to 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 has to be replaced. It can wear out 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 Breaks Down
Your furnace will show 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 quick flashes or an alternating slow flash as it shares a fault code.
Estimated Repair Cost for Furnace Error Code 270
The bill to fix your furnace hinges on what’s wrong with it and the amount of time it takes to remedy 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 blockages 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 typical costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
