Designed for use in residential forced-air furnaces, this essential air-proving component monitors the pressure differential within the draft inducer motor housing to confirm proper airflow before the ignition sequence begins. If your furnace is failing to ignite or displaying a pressure switch lockout error, this replacement part provides a reliable solution. This dual-port vacuum switch is factory-calibrated to a precise -0.70 inch WC set point, making it critical for maintaining safety standards and preventing the buildup of dangerous combustion gases.
