Description
Ensure safe, reliable operation of your furnace or HVAC system with the York S1-024-35286-000 Pressure Switch, a genuine OEM-grade part engineered to monitor combustion- and ventilation-air pressure and keep your system operating under correct conditions.
Key Features
- OEM-certified component: Made by York to guarantee compatibility and dependable performance in systems originally built for this part.
- Precise vacuum activation: Calibrated to trigger at –0.9" WC (water column) — designed to close on falling pressure (“SPNO Close-on-Fall”), ensuring the control circuit activates only when proper draft or airflow is present.
- Essential safety function: Helps ensure that inducer motors and venting create the needed vacuum before ignition or blower operation, reducing risk of unsafe combustion or inadequate airflow.
- Compact & easy to install: Standard form factor and wiring terminals make it straightforward to replace on compatible furnace or HVAC units.
