How a Furnace Ignitor Works
This part ignites natural gas, which helps heat your house.
Here’s how a furnace ignitor works:
- Thermostat begins call for heat.
- Furnace ignitor and blower become triggered.
- Ignitor heats to as hot as 2,500 degrees Fahrenheit and ignites burner gas.
A furnace ignitor should last about three to five years before it breaks and must be replaced. It can wear out sooner if you don’t replace your air filter routinely, since a dirty one can cause your heating system to short cycle.
What Happens When a Furnace Ignitor Fails
Your furnace will demonstrate for 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 fast 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 time it takes to remedy 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 obstructions or cracked hoses within your home.
An ignitor always seems to fail when you need it most, bringing about an after-hours service call.
Here’s the usual costs to replace it:
- $200 during normal service hours
- $300 to $400 after hours
