This premium air pressure switch is a vital safety component designed for use in high-efficiency gas furnaces and residential heating systems. Functioning as an air proving switch, it monitors the pressure differential created by the draft inducer motor to ensure that flue gases are being properly vented before the ignition sequence begins. With a factory-calibrated trip point of 1.15" WC (Water Column), this switch protects your HVAC equipment by preventing operation during vent blockages or inducer motor failures. It is a standard replacement part for resolving common furnace lockout issues and no-heat conditions caused by faulty pressure sensors.
