Getting cold because you’re getting error code 270 from your Lennox® furnace?
This means your furnace ignitor can’t turn on the flame. After five failed attempts, the furnace will halt trying to ignite. It will then switch into Watchguard mode for about an hour for safety reasons.
When your ignitor ceases working, it’s better to depend on our ACE-certified technicians. They’ve gone through detailed instruction, so you can rest easy knowing they’ll discover what’s generating the furnace error and will repair 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 your home.
Here’s how a furnace ignitor works:
- Thermostat starts call for heat.
- Furnace ignitor and blower become energized.
- 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 breaks and must be replaced. It can stop working sooner if you don’t replace your air filter when needed, since a clogged one can cause your HVAC equipment to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will demonstrate for you there’s something wrong with a red flash from its indicator light, which it uses to exhibit 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 bill to restore your furnace depends on what the issue is with it and the amount of time it takes to remedy it.
Before your technician replaces your ignitor, he or she will investigate:
- Gas flow
- Flame sensor current
- Air filter
Your HVAC specialist will also make sure the ignitor is actually lighting the burner and that there are no obstructions or cracked hoses within your home.
An ignitor often fails when you need it most, resulting in an after-hours trip charge.
Here’s the typical costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
