This premium air pressure switch is a critical safety component designed for two-stage gas furnaces and HVAC systems. As an essential air proving switch, it monitors the vacuum pressure created by the draft inducer motor to ensure proper venting and combustion airflow. If the switch detects a blockage or a failure in the blower motor, it prevents the furnace from igniting, protecting your home from potential hazards. Specifically calibrated for dual-stage heating, this part features precise trip points of 0.55" WC and 0.95" WC to manage low and high-fire operation. Constructed for durability and consistent performance, it is the ideal replacement for a malfunctioning pressure sensor in high-efficiency residential heating units.
