Product Details

Description

This premium air pressure switch is a vital safety component for residential gas furnaces and HVAC heating systems. Often referred to as an air proving switch, its primary function is to monitor the draft inducer motor's operation, ensuring that the heating system has adequate airflow and proper venting before allowing the ignition process to begin. If your furnace is failing to ignite or shuts down mid-cycle, a faulty pressure switch may be the cause. This high-quality replacement part is designed to restore reliable performance, protecting your home by preventing the burner from operating under unsafe conditions. Built for durability and precise calibration, it is an essential repair part for maintaining the efficiency and safety of forced-air heating units.
