Product Details

Description

This premium two-stage air pressure switch is a vital safety component for high-efficiency residential gas furnaces. Engineered as an air proving switch, it continuously monitors the pressure differential produced by the inducer motor to ensure proper venting and safe combustion throughout the heating cycle. If your furnace is experiencing ignition failure, intermittent cycling, or showing a pressure switch lockout code, this dual-stage replacement part is designed to restore reliable operation. It features two distinct calibrated setpoints to accommodate the varying airflow requirements of multi-stage heating systems, ensuring the appliance operates at peak efficiency while maintaining strict safety standards.
