Description
The York S1-32435972000 Pressure Switch monitors air pressure at a 0.10″ WC setting to confirm proper airflow conditions before heating equipment proceeds through operating sequences. Operating through pressure-sensitive activation, it responds to airflow changes inside the system and allows equipment operation only when required pressure levels are achieved. Positioned within furnace assemblies as a substitution for S1-02541003000 and S1-02427666001, this component acts with an essential purpose in HVAC systems by contributing to orderly ignition and air flow verification for improved equipment performance.
