When your ignitor stops working, it’s best to count on our NATE-certified technicians. They’ve gone through important training, so you can rest easy knowing they’ll discover what’s causing the furnace error and will fix it to your standards.
We are confident in the quality of our furnace repair in Nashville 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 warm your house.
Here’s how a furnace ignitor works:
- Thermostat launches 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 about three to five years before it fractures and needs to be replaced. It can wear out sooner if you don’t replace your air filter routinely, since a clogged one can cause your furnace to short cycle.
What Happens When a Furnace Ignitor Fails
Your furnace will show you there’s a problem 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 short flashes or an alternating slow flash as it shares a fault code.
Estimated Repair Cost for Furnace Error Code 270
The bill to restore your furnace depends on what’s wrong with it and the time it takes to repair 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 home.
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
