This means your furnace ignitor can’t activate 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 isn’t working, it’s best to depend on our ACE-certified technicians. They’ve gone through rigorous training, so you can rest easy knowing they’ll find out what’s causing 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 starts call for heat.
- Furnace ignitor and blower become activated.
- 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 breaks and must be replaced. It can stop working sooner if you don’t replace your air filter regularly, since a clogged one can cause your HVAC equipment to short cycle.
What Happens When a Furnace Ignitor Stops Working
Your furnace will tell you there’s something wrong with a red flash from its indicator light, which it uses to communicate 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 bill to mend your furnace rests on what’s wrong with it and how long it takes to correct it.
Before your technician replaces your ignitor, he or she will investigate:
- 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 blockages or cracked hoses within your home.
An ignitor often fails when you need it most, bringing about an after-hours trip charge.
Here’s the average costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
