Product Details

Description

Ensure the safe and efficient operation of your heating system with this high-quality Lennox Air Pressure Switch. Specifically calibrated for a -0.10" WC (Water Column) set point, this air proving switch serves as a critical safety mechanism by monitoring the airflow and negative pressure within your furnace or package unit's combustion chamber. It is designed to prevent the ignition cycle from proceeding if the inducer motor is not venting properly or if there is a blockage in the flue, protecting your property from potential exhaust hazards. If your HVAC system is experiencing ignition failure, error codes related to pressure, or short-cycling, this replacement differential pressure switch is a common solution for restoring reliable performance. Built for durability and precision, it is an essential component for maintaining the air proving requirements of residential and commercial forced-air heating equipment.
