It senses negative pressure from the inducer motor and only closes its contacts when airflow is safe, preventing dangerous operation with a blocked vent or failed inducer. If your furnace runs the inducer but never lights, or locks out on a pressure-switch fault code, this component or a clogged hose is usually to blame. Engineered as a direct-fit replacement for the GB1AAV060155ABJA, this genuine switch is calibrated to the exact trip pressure your system needs — generic switches with wrong setpoints can cause unsafe operation or constant lockouts. Installation is easy, about 15-20 minutes: cut power, disconnect the hose and wires, unscrew the switch, and reverse. Using the authentic Carrier part ensures safe, code-correct draft proving.
