Feeling a chill because you’re getting error code 270 from your Lennox® furnace?
This shows you that your furnace ignitor can’t start the flame. After five failed tries, the furnace will stop trying to ignite. It will then switch into Watchguard mode for about an hour for safety reasons.
When your ignitor stops working, it’s safer to rely on our ACE-certified technicians. They’ve gone through important instruction, so you can rest easy knowing they’ll determine what’s generating the furnace error and will mend it to your contentment.
We trust in the quality of our furnace repair* for a year.
How a Furnace Ignitor Works
This part ignites natural gas, which helps heat your house.
Here’s how a furnace ignitor works:
- Thermostat begins call for heat.
- Furnace ignitor and blower become energized.
- 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 must be changed out. It can wear out sooner if you don’t replace your air filter regularly, since a dusty one can cause your HVAC equipment to short cycle.
What Happens When a Furnace Ignitor Fails
Your furnace will demonstrate for you there’s something wrong 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 rests on the problem with it and the amount of time it takes to correct it.
Before your technician replaces your ignitor, he or she will look at:
- Gas flow
- Flame sensor current
- Air filter
Your technician 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, resulting in an after-hours trip charge.
Here’s the average costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
