It reads negative pressure through a sensing hose; a blocked flue, a tired inducer motor, or a failed switch keeps the contacts open and the furnace won't fire, typically flashing a pressure-switch error code. This switch is calibrated to the precise water-column trip point and port layout specified for the GB3AAV036050AEJA, ensuring safe and accurate operation. Installation is quick—roughly 15 minutes—remove one or two screws, move the hose and spade connectors to the new switch, and remount it. Always disconnect power first and check the sensing hose for cracks or trapped condensate while you have access. A combustion safety is no place for a mis-rated generic; install the correct genuine OEM switch.
