Burner Failure: Is It An All-Or-Nothing Problem?
Your furnace's burners serve a fairly critical function—they distribute the gas that your furnace ultimately burns to provide heat for your home. Most furnaces contain a single burner unit, but some units usually have multiple individual burner tubes. A typical design includes a manifold that distributes gas to each burner to provide clean and even heat. Burner units are relatively simple components, but they can still suffer from several potential failures.
