Product Details

Description

This premium air pressure switch is an essential safety component for modern gas furnaces and HVAC heating systems. Functioning as an air-proving switch, it is designed to monitor the negative pressure created by the draft inducer motor, ensuring that the combustion process only begins when proper airflow and venting are confirmed. With a precise calibrated set point of 0.28" WC (Water Column), this switch prevents the furnace from operating under unsafe conditions, such as a blocked vent or a failing inducer fan. Replacing a worn or malfunctioning pressure switch can restore reliable ignition and improve the overall safety and efficiency of your heating equipment. It is an ideal solution for fixing common furnace startup issues related to airflow detection and inducer motor performance.
