Feeling a chill because you’re seeing error code 270 from your Lennox® furnace?
This means your furnace ignitor can’t activate the flame. After five failed tries, the furnace will stop trying to ignite. It will then change into Watchguard mode for about an hour for safety reasons.
When your ignitor isn’t working, it’s better to depend on our ACE-certified technicians. They’ve gone through detailed education, so you can rest easy knowing they’ll discover what’s generating the furnace error and will mend 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 warm your house.
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 must be subbed out for a new part. It can break down sooner if you don’t replace your air filter regularly, since a clogged one can cause your furnace to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will tell you there’s a problem 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 short flashes or an alternating slow flash as it shares a fault code.
