This high-performance Lennox air pressure switch is a vital safety and operational component designed for modern HVAC systems. Functioning as an air proving switch, this part monitors the pressure differential within the system to ensure the inducer fan or blower is moving air correctly before the heating or cooling cycle is permitted to begin. If your HVAC unit is experiencing ignition failure or intermittent shutdowns due to airflow errors, this precision-calibrated sensor is a reliable solution for restoring safe and efficient operation. Engineered for accuracy and long-term durability, it features dual setpoints to maintain rigorous performance standards in various heating and ventilation environments.
