Product Details

Description

Ensure the safe and efficient operation of your heating system with this premium dual-stage air pressure switch. Designed as a critical safety mechanism for high-efficiency gas furnaces, this air proving switch monitors the airflow and pressure created by the draft inducer motor. It confirms that the system is venting exhaust gases correctly before allowing the furnace to ignite, preventing hazardous conditions. This specific component is engineered for two-stage heating units, featuring precisely calibrated set points of 0.15" WC and 0.83" WC to manage varying blower speeds. If your furnace is experiencing ignition failure, error codes, or intermittent cycling, replacing a worn or faulty pressure switch can restore reliable performance and consistent home comfort.
