Getting cold 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 halt trying to ignite. It will then go into Watchguard mode for about an hour for your protection.
When your ignitor isn’t working, it’s best to count on our ACE-certified technicians. They’ve gone through detailed training, so you can rest easy knowing they’ll determine what’s causing the furnace error and will mend it to your contentment.
We trust 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 begins 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 about three to five years before it cracks and must 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 HVAC equipment to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will show you there’s an issue 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 cost to mend your furnace rests on what the issue is with it and how long 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 pro will also make sure the ignitor is truly lighting the burner and that there are no blockages 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 usual costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
