York S1-024-35282-000 Switch

The York S1-024-35282-000 Switch is a critical safety component designed for precise pressure monitoring within York, Luxaire, and Coleman gas furnaces and air handlers. This OEM pressure switch features a Single Pole Normally Open (SPNO) configuration, specifically engineered to close on fall. With a calibrated setpoint range of -.4" to -.9" WC, it ensures the inducer motor is moving sufficient combustion air before ignition occurs. If you are encountering a 'pressure switch stuck open' code on a York HVAC system, this direct replacement eliminates the guesswork often found with universal components. The durable housing is built to withstand high-static environments and frequent cycling. For field technicians, verifying the specific SPNO Close On Fall operation is essential for circuit integrity. This switch provides the exact technical tolerances required to maintain factory airflow specifications and safe furnace operation through every heating cycle.

• Genuine OEM York replacement part ensures exact mounting and electrical compatibility without modifications.
• Factory-calibrated -.4" to -.9" WC setpoints prevent nuisance trips and ensure proper drafting.
• SPNO logic (Single Pole Normally Open) facilitates standard safety string wiring to the integrated furnace control.
• Designed for high-reliability switching in demanding residential and commercial HVAC applications.

How do I know if the York S1-024-35282-000 is failing?

Look for inducer motor operation without ignition or LED fault codes on the control board indicating the pressure switch failed to close or stayed open. Use a manometer to verify if the inducer is pulling the required -.4" to -.9" WC before condemning the switch.

Can I use a universal pressure switch instead of the S1-024-35282-000?

While adjustable switches exist, they often lack the precise calibration needed for specific York combustion blower profiles. Using the OEM switch ensures the system operates within its tested safety parameters.

Does orientation matter when installing this switch?

Yes, to prevent moisture and condensation buildup in the diaphragm, always follow the manufacturer's vertical or horizontal mounting requirements as specified in the service manual.
