Product Details

Description

This premium air pressure switch is a vital safety component designed for modern HVAC systems and forced-air furnaces. Functioning as an air-proving sensor, it monitors the vacuum pressure created by the draft inducer motor to ensure proper venting of combustion gases before the ignition sequence begins. Rated at a precise 1.20" WC (Water Column), this switch prevents the heating system from operating under unsafe conditions, such as a blocked flue or a failing blower motor. If your furnace is failing to ignite or throwing a pressure switch error code, this high-quality replacement part is essential for restoring reliable and efficient heating performance. Crafted for durability and precision, it ensures your residential or commercial heating equipment meets rigorous safety standards.
