This ICP Air Pressure Switch is a critical safety component designed for high-efficiency gas furnaces and HVAC systems. Rated at a 0.50" WC (Water Column) set point, this air proving switch monitors the pressure generated by the inducer motor to ensure proper venting of combustion gases before allowing the furnace to ignite. If your heating system is experiencing ignition failure, throwing pressure switch error codes, or if the inducer fan runs without the burners lighting, this replacement part is essential for restoring safe and reliable operation. Built to meet rigorous industry standards, it helps maintain the efficiency and safety of your residential heating equipment.
