Product Details

Description

This premium air pressure switch is a critical safety component designed for residential and commercial heating systems. As an air-proving switch, it monitors the pressure within the furnace combustion chamber to ensure the inducer fan is moving air correctly before the ignition process begins. Rated at 0.55" WC (Water Column) with an SPST (Single Pole Single Throw) configuration, this switch helps prevent the furnace from operating under unsafe venting conditions. It is a high-quality replacement part specifically engineered for Lennox HVAC systems, commonly used to resolve ignition failures, intermittent furnace cycling, and pressure switch lockout codes.
