Feeling a chill because you’re getting error code 270 from your Lennox® furnace?
This shows you that your furnace ignitor can’t activate the flame. After five failed tries, the furnace will quit 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 education, so you can rest easy knowing they’ll determine what’s generating the furnace error and will repair 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 up your space.
Here’s how a furnace ignitor works:
- Thermostat launches call for heat.
- Furnace ignitor and blower become triggered.
- Ignitor becomes 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 replaced. It can break down sooner if you don’t replace your air filter regularly, since a dirty one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Fails
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 fast 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 hinges on the problem with it and the time it takes to remedy 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 actually lighting the burner and that there are no interferences 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
