Product Details

Description

This premium two-stage air pressure switch is a vital safety and performance component designed for high-efficiency gas furnaces. As an integral part of the combustion process, this air-proving switch monitors the pressure produced by the inducer motor to ensure proper venting and airflow before allowing the furnace to ignite. Specifically calibrated for dual-stage heating systems, it features two distinct setpoints (0.95" WC and 0.15" WC) to accurately manage different levels of heat output. Replacing a faulty pressure switch can resolve common HVAC issues such as furnace ignition failure, intermittent cycling, or pressure switch lockout codes. Engineered for reliability and precision, this component ensures your heating system operates safely by preventing gas flow if venting obstructions or motor failures are detected.
