Feeling a chill because you’re seeing error code 270 from your Lennox® furnace?
This means your furnace ignitor can’t start the flame. After five failed tries, the furnace will quit trying to ignite. It will then go into Watchguard mode for about an hour for your protection.
When your ignitor ceases working, it’s best to depend on our ACE-certified technicians. They’ve gone through rigorous training, so you can rest easy knowing they’ll determine what’s causing the furnace error and will mend it to your standards.
We believe in the quality of our furnace repair* for a year.
How a Furnace Ignitor Works
This part ignites natural gas, which helps warm your house.
Here’s how a furnace ignitor works:
- Thermostat launches call for heat.
- Furnace ignitor and blower become activated.
- Ignitor heats 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 has to be replaced. It can break down sooner if you don’t replace your air filter routinely, since a clogged one can cause your HVAC equipment to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will tell 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 quick flashes or an alternating slow flash as it shares a fault code.
Estimated Repair Cost for Furnace Error Code 270
The bill to mend your furnace depends on the problem with it and how long it takes to correct it.
Before your technician replaces your ignitor, he or she will look at:
- Gas flow
- Flame sensor current
- Air filter
Your technician 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, 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
