Description
The York S1-02434612000 Air Pressure Switch is an essential control components designed for use in gas furnaces to monitor airflow and venting conditions. Configured as normally open, it activates at 1.20″ WC and deactivates at 0.40″ WC, responding to pressure changes within the air combustion HVAC systems. Installed in the inducer or venting circuit, it check proper draft before allowing ignition, to avoid unsafe operation due to blocked flues or inadequate airflow. This component plays a vital role within the system by enabling safe startup sequencing, maintaining operational accurate, and supporting proper combustion performance in residential applications.
