Feeling a chill because you’re seeing error code 270 from your Lennox® furnace?
This indicates your furnace ignitor can’t turn on the flame. After five failed efforts, 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 better to depend on our ACE-certified technicians. They’ve gone through detailed training, so you can rest easy knowing they’ll find out 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 heat your space.
Here’s how a furnace ignitor works:
- Thermostat begins 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 must be replaced. It can break down sooner if you don’t replace your air filter when needed, since a clogged one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Fails
Your furnace will tell you there’s something wrong 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 short 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 rests on what’s wrong with it and how long 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 interferences or cracked hoses within your system.
An ignitor often fails 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
