Feeling a chill because you’re noticing error code 270 from your Lennox® furnace?
This shows you that your furnace ignitor can’t start the flame. After five failed attempts, the furnace will quit trying to ignite. It will then switch into Watchguard mode for about an hour for your protection.
When your ignitor stops working, it’s better to depend on our NATE-certified technicians. They’ve gone through important training, so you can rest easy knowing they’ll determine what’s causing the furnace error and will fix it to your standards.
We trust in the quality of our furnace repair in Concord so much, we back it with a 100% Satisfaction Guarantee* for a year.
How a Furnace Ignitor Works
This part ignites natural gas, which helps warm up your home.
Here’s how a furnace ignitor works:
- Thermostat begins 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 roughly three to five years before it fractures and has to be changed out. It can break down sooner if you don’t replace your air filter regularly, since a dusty one can cause your HVAC equipment to short cycle.
What Happens When a Furnace Ignitor Breaks Down
Your furnace will tell 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 quick flashes or an alternating slow flash as it shares a fault code.
Estimated Repair Cost for Furnace Error Code 270
The cost to mend your furnace hinges on the problem with it and the amount of time it takes to repair 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 actually lighting the burner and that there are no blockages or cracked hoses within your home.
An ignitor always seems to fail when you need it most, prompting an after-hours repair call.
Here’s the typical costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
