Feeling a chill because you’re noticing error code 270 from your Lennox® furnace?
This shows you that your furnace ignitor can’t activate the flame. After five failed attempts, the furnace will stop trying to ignite. It will then go into Watchguard mode for about an hour for your safety.
When your ignitor ceases working, it’s safer to count on our ACE-certified technicians. They’ve gone through important training, so you can rest easy knowing they’ll find out what’s generating the furnace error and will repair it to your satisfaction.
We are confident in the quality of our furnace repair* for a year.
How a Furnace Ignitor Works
This part ignites natural gas, which helps warm up your house.
Here’s how a furnace ignitor works:
- Thermostat begins call for heat.
- Furnace ignitor and blower become triggered.
- Ignitor warms to as hot as 2,500 degrees Fahrenheit and ignites burner gas.
A furnace ignitor should last approximately three to five years before it breaks and must be replaced. It can stop working sooner if you don’t replace your air filter routinely, since a dirty one can cause your HVAC equipment to short cycle.
What Happens When a Furnace Ignitor Breaks Down
Your furnace will show 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.
Estimated Repair Cost for Furnace Error Code 270
The cost to fix your furnace rests on what’s wrong with it and how long it takes to repair it.
Before your technician replaces your ignitor, he or she will check:
- Gas flow
- Flame sensor current
- Air filter
Your HVAC pro will also make sure the ignitor is actually 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, 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
