York S1-024-35308-000 0.60″WC SPST Pressure Switch

Description

The York S1-024-35308-000 is an OEM replacement SPST (Single-Pole, Single-Throw) pressure switch engineered to deliver dependable performance in York heating and HVAC systems. Calibrated to a set point of 0.60″ water column (WC), this switch monitors system pressure and provides a critical safety interlock — shutting down or enabling operation when pressure falls outside acceptable limits.

Key Features

• OEM York replacement pressure switch — ensures precise fit and function
• Set point: 0.60″ WC (water column)
• SPST (Single-Pole, Single-Throw) switching configuration
• Monitors draft pressure to protect against unsafe operating conditions
• Designed for use in York furnaces and air handling equipment
• Direct drop-in replacement for simplified installation

Application

This pressure switch is commonly used in York furnaces and HVAC systems to verify proper inducer/draft operation before allowing ignition. When the inducer motor creates sufficient negative pressure, the switch closes (or opens, depending on application), signaling the control board to proceed with the ignition sequence. A faulty or out-of-spec pressure switch can cause lockout conditions, making timely replacement essential for restoring reliable system operation.
