Feeling a chill because you’re seeing 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 stop trying to ignite. It will then switch into Watchguard mode for about an hour for your safety.
When your ignitor ceases working, it’s better to rely on our ACE-certified technicians. They’ve gone through rigorous instruction, so you can rest easy knowing they’ll find out what’s generating the furnace error and will fix it to your standards.
We trust 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 starts 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 about three to five years before it breaks and has to be subbed out for a new part. It can break down sooner if you don’t replace your air filter routinely, since a dusty 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 an issue 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 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 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 pro will also make sure the ignitor is actually lighting the burner and that there are no blockages or cracked hoses within your home.
An ignitor often fails when you need it most, bringing about an after-hours trip charge.
Here’s the typical costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
