Product Details

Description

This Lennox Air Pressure Switch is a critical safety component designed for high-efficiency HVAC systems and residential gas furnaces. As an air-proving switch, it monitors the pressure within the combustion chamber to ensure the inducer fan motor is creating the necessary draft for safe operation. Featuring a 0.65" WC (Water Column) set point and SPST (Single Pole Single Throw) circuitry, this switch prevents the heating cycle from proceeding if venting issues or blockages are detected. This replacement part is essential for resolving common furnace ignition failures and ensuring the long-term reliability and safety of your heating equipment.
