Feeling frigid 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 attempts, the furnace will halt trying to ignite. It will then go into Watchguard mode for about an hour for your protection.
When your ignitor ceases working, it’s safer to count on our ACE-certified technicians. They’ve gone through important instruction, so you can rest easy knowing they’ll discover what’s generating the furnace error and will fix it to your satisfaction.
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 house.
Here’s how a furnace ignitor works:
- Thermostat launches call for heat.
- Furnace ignitor and blower become triggered.
- Ignitor heats to as hot as 2,500 degrees Fahrenheit and ignites burner gas.
A furnace ignitor should last roughly three to five years before it breaks and has to be subbed out for a new part. It can stop working sooner if you don’t replace your air filter when needed, since a dusty one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Fails
Your furnace will demonstrate for 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 short flashes or an alternating slow flash as it shares a fault code.
Estimated Repair Cost for Furnace Error Code 270
The cost to mend your furnace rests on what’s wrong with it and the time it takes to remedy it.
Before your technician replaces your ignitor, he or she will investigate:
- Gas flow

Your HVAC pro will also make sure the ignitor is actually lighting the burner and that there are no obstructions or cracked hoses within your equipment.

- $200 during normal service hours
