My furnace wasn't staying lit, it would attempt to start going through the opening cycle 3 times before shutting down. Red and Green fast flashing lights as an error code. This is how I fixed it and saved some money. I'll need to replace the flame sensor but this simple trick saved me from a freezing cold house at 2AM until the stores open.
