Getting cold because you’re noticing error code 270 from your Lennox® furnace?
This indicates 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 ceases working, it’s better to depend on our NATE-certified technicians. They’ve gone through rigorous instruction, so you can rest easy knowing they’ll determine what’s causing the furnace error and will fix it to your standards.
We believe in the quality of our furnace repair 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 heat your home.
Here’s how a furnace ignitor works:
- Thermostat launches 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 roughly three to five years before it breaks and has to be changed out. It can stop working sooner if you don’t replace your air filter routinely, since a dusty one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will tell 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 short flashes or an alternating slow flash as it shares a fault code.
Estimated Repair Cost for Furnace Error Code 270
The price to mend your furnace depends on the problem with it and the amount of time it takes to correct it.
Before your technician replaces your ignitor, he or she will check:
- 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 blockages or cracked hoses within your system.
An ignitor always seems to fail when you need it most, prompting an after-hours maintenance call.
Here’s the average costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
