Product Details

Description

This Lennox 2-stage air pressure switch is an essential safety and performance component for high-efficiency gas furnaces and HVAC systems. Designed as an air proving switch, it monitors the pressure differential created by the inducer motor to ensure combustion gases are being safely exhausted. Featuring dual setpoints at 1.00" WC and 0.25" WC, this switch is specifically engineered for two-stage heating applications, allowing the system to verify proper airflow at both low and high heat cycles. If the switch detects a venting blockage or mechanical failure, it safely interrupts the ignition sequence to prevent hazardous operation. This durable replacement part is vital for restoring the reliability and efficiency of residential heating equipment.
