Feeling frigid because you’re getting error code 270 from your Lennox® furnace?
This means your furnace ignitor can’t activate the flame. After five failed tries, the furnace will stop trying to ignite. It will then go into Watchguard mode for about an hour for safety reasons.

Here’s how a furnace ignitor works:
A furnace ignitor should last approximately three to five years before it cracks and needs to be replaced. It can wear out sooner if you don’t replace your air filter regularly, since a dirty one can cause your furnace to short cycle.
