Ensure your HVAC system operates safely and efficiently with this high-quality Air Pressure Switch. Designed for use in residential gas furnaces, this air-proving switch monitors the pressure created by the draft inducer motor to verify proper airflow through the heat exchanger. It acts as a critical safety mechanism, preventing the ignition of the burner if the venting system is obstructed or if the inducer fan fails to reach the necessary speed. With a precise 0.66" WC (Water Column) set point, this component ensures your heating system meets strict safety protocols. If your furnace is experiencing ignition failure, short-cycling, or error codes related to airflow, replacing a faulty pressure switch is a common and necessary repair to restore reliable heating performance.
