Getting cold 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 tries, the furnace will halt trying to ignite. It will then change into Watchguard mode for about an hour for safety reasons.
When your ignitor stops working, it’s better to rely on our NATE-certified technicians. They’ve gone through important education, so you can rest easy knowing they’ll find out what’s generating the furnace error and will mend it to your contentment.
We trust in the quality of our furnace repair in Longmont 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 space.
Here’s how a furnace ignitor works:
- Thermostat starts call for heat.
- Furnace ignitor and blower become energized.
- Ignitor becomes as hot as 2,500 degrees Fahrenheit and ignites burner gas.
A furnace ignitor should last approximately three to five years before it fractures and must 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 Fails
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 fix your furnace depends on what’s wrong with it and how long it takes to repair it.
Before your technician replaces your ignitor, he or she will investigate:
- Gas flow
- Flame sensor current
- Air filter
Your technician will also make sure the ignitor is legitimately lighting the burner and that there are no interferences 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
