This premium dual-stage air pressure switch is an essential safety component for high-efficiency HVAC heating systems. Designed to function as an air proving sensor, it monitors the vacuum pressure generated by the draft inducer motor to ensure combustion gases are safely vented before the ignition process begins. Featuring two distinct set points, this switch is specifically engineered for two-stage furnaces, providing precise monitoring for both low-fire and high-fire operations. If your heating system is experiencing ignition failure, frequent cycling, or error codes related to airflow, replacing the pressure switch can restore reliable performance and ensure the safe operation of your furnace.
