York S1-024-25006-710 Pressure Switch Overview
The York S1-024-25006-710 is an OEM replacement pressure switch designed to deliver dependable performance in York heating systems. Calibrated to a set point of 0.65″ WC (inches water column), this switch monitors negative pressure created by the draft inducer motor to verify safe combustion venting conditions before allowing the burner to ignite — a critical safety function in modern gas furnaces.
Key Features
- OEM York replacement part — direct fit for compatible York furnace models
- Set point: 0.65″ WC (inches water column)
- Monitors draft inducer pressure to confirm proper venting before ignition
- Helps prevent unsafe furnace operation due to blocked flue or inducer failure
- Engineered to meet OEM specifications for accuracy and longevity
- Simple drop-in replacement for fast, straightforward service calls
How It Works
The pressure switch is a safety device that senses the negative pressure (vacuum) generated by the draft inducer blower. When the inducer reaches the correct operating speed and airflow, the pressure differential closes the switch, signaling the control board to proceed with ignition. If the required pressure is not achieved — due to a blocked flue, failed inducer, or cracked switch hose — the switch remains open and locks out the furnace, protecting occupants from potential carbon monoxide hazards.
Application
- Designed for use in York gas furnaces requiring a 0.65″ WC pressure switch
- Always verify compatibility with your specific York model number before installation
- Recommended for installation by qualified HVAC technicians
