Feeling a chill 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 go into Watchguard mode for about an hour for your safety.
When your ignitor ceases working, it’s safer to rely on our ACE-certified technicians. They’ve gone through detailed instruction, so you can rest easy knowing they’ll determine what’s creating the furnace error and will fix it to your standards.
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 house.
Here’s how a furnace ignitor works:
- Thermostat begins call for heat.
- Furnace ignitor and blower become triggered.
- 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 must be changed out. It can stop working sooner if you don’t replace your air filter routinely, since a dirty 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 communicate 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 price to restore your furnace depends on the problem with it and how long it takes to correct it.
Before your technician replaces your ignitor, he or she will check:
- Gas flow
- Flame sensor current
- Air filter
Your technician will also make sure the ignitor is legitimately lighting the burner and that there are no obstructions or cracked hoses within your home.
An ignitor always seems to fail 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
