The CF441L is a 24 VAC direct replacement Lennox furnace board with a dual microprocessor-based design intended for 100% gas shutoff in case of ignition/flame relay control failure. This item is a Single-Stage BASO model that replaces 36 different Lennox models. The board connectors allow the user to hookup directly to the furnace without the need for a separate cable harness with the board.
