How a Furnace Ignitor Works

This part ignites natural gas, which helps heat your house.

Here’s how a furnace ignitor works:

  • Thermostat launches call for heat.
  • Furnace ignitor and blower become activated.
  • Ignitor heats to as hot as 2,500 degrees Fahrenheit and ignites burner gas.

A furnace ignitor should last approximately three to five years before it cracks and has to be subbed out for a new part. It can wear out sooner if you don’t replace your air filter regularly, since a clogged one can cause your furnace to short cycle.

What Happens When a Furnace Ignitor Stops Working

Your furnace will show you there’s an issue with a red flash from its indicator light, which it uses to display 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 restore your furnace hinges on what’s wrong with it and how long it takes to repair it.

  • Gas flow

  • $200 during normal service hours
