The CF442L 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 replaces 29 different Two-Stage and Variable Speed 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.
