This high-quality Pressure Switch Assembly is a vital safety component for residential gas furnaces and HVAC systems. As an air proving switch, it is designed to monitor the pressure differential created by the inducer motor, ensuring that the heating system is venting exhaust gases safely and efficiently before allowing the ignition sequence to proceed. If your furnace is failing to ignite or shutting off prematurely, a faulty pressure sensor may be the cause. This assembly provides a reliable replacement to restore proper furnace operation, featuring a durable design and precise calibration to meet strict safety standards. It is an essential part for maintaining the performance and safety of forced-air heating units.
