Description
The York S1-024-36052-008 is an OEM replacement pressure switch designed to deliver dependable performance in York heating systems. Calibrated to a precise set point of -0.38″ water column (WC), this switch monitors draft pressure within the furnace to confirm that the inducer motor is operating correctly before allowing ignition to proceed — a critical safety function that protects both equipment and occupants.
How It Works
The pressure switch senses negative pressure generated by the draft inducer. When the inducer establishes the correct airflow, the switch closes, signaling the control board to advance through the ignition sequence. If adequate pressure is not detected — due to a blocked flue, failed inducer, or clogged condensate line — the switch remains open, locking out ignition and preventing unsafe operation.
