Feeling a chill because you’re noticing error code 270 from your Lennox® furnace?
This indicates your furnace ignitor can’t turn on 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 your safety.
When your ignitor stops working, it’s best to rely on our ACE-certified technicians. They’ve gone through rigorous education, so you can rest easy knowing they’ll find out what’s causing the furnace error and will fix it to your satisfaction.
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 activated.
- Ignitor warms to as hot as 2,500 degrees Fahrenheit and ignites burner gas.
A furnace ignitor should last approximately 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 routinely, since a clogged one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will demonstrate for you there’s a problem 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 restore 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 check:
- Gas flow
- Flame sensor current
- Air filter
Your HVAC pro will also make sure the ignitor is actually lighting the burner and that there are no blockages or cracked hoses within your system.
An ignitor always seems to fail 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
