Replacement HVAC Part

Genuine OEM replacement pressure switch designed for York, Coleman, and Luxaire HVAC systems. This factory-original component is engineered to monitor airflow and ensure safe furnace operation by detecting negative pressure differentials in the combustion air intake. The switch features a single pole normally open (SPNO) configuration that closes when pressure falls to the set point of 0.50 inches water column, triggering the control circuit to verify proper draft conditions before allowing the furnace to operate. With an electrical rating of 125VAC at 10A, this switch integrates seamlessly into existing HVAC control systems and meets original equipment specifications. The part is brand new and unmodified, providing reliable performance equivalent to original furnace components. This pressure switch is essential for furnace safety interlocks, preventing operation when draft or airflow conditions are inadequate. Installation is suitable for qualified HVAC technicians servicing York, Coleman, and Luxaire heating systems. As a critical safety component, this OEM switch ensures compliance with furnace manufacturer requirements and maintains proper system diagnostics. Use as a direct replacement to restore original equipment functionality and reliability in residential or light commercial heating applications.
