York S1-024-36052-008 Pressure Switch

The York S1-024-36052-008 Pressure Switch is a critical safety component designed for precise -0.38" WC differential atmospheric pressure monitoring in York residential and commercial furnaces. As an official OEM replacement part, this air pressure switch serves as the direct updated version for S1-024-25006-705, ensuring seamless mechanical and electrical integration without the need for field modifications or bracket fabrication. This component is essential for verifying proper inducer motor operation and venting integrity before allowing the ignition sequence to proceed.

For service technicians, the S1-024-36052-008 offers a factory-calibrated set point of -0.38" WC, maintaining the high sensitivity required to detect minor fluctuations in combustion airflow. This furnace pressure switch is constructed with durable housing and corrosion-resistant terminals to withstand the thermal cycling and moisture typical of condensing furnace environments. It is primary compatible with York PBNU-LD12N100A systems and related HVAC equipment, serving as a reliable drop-in for legacy York furnace replacement parts.

• OEM Compatibility: Specifically engineered as the direct replacement for S1-024-25006-705, ensuring accurate trip points and HVAC part reliability.
• Factory Calibrated: Set at -0.38 inch water column to meet strict manufacturer specifications for proper exhaust venting safety.
• Robust Construction: Designed to resist diaphragm fatigue, preventing nuisance limit switch trips and system lockouts.
• Enhanced HVAC Performance: Optimizes combustion safety by ensuring the burner only fires when sufficient airflow is present.

What does the -0.38" WC rating mean for my system?
This rating specifies the negative pressure threshold required to close the switch. If your vent pipe or heat exchanger is restricted, or the inducer fan underperforms, the switch will not close, preventing the furnace from firing as a safety precaution.

Is the S1-024-36052-008 compatible with older York furnace models?
Yes, this is the official replacement part for the older S1-024-25006-705 model. It is designed to fit PBNU-LD12N100A series units and other York and Coleman furnace equipment requiring a -0.38" WC set point.

Can I use a universal pressure switch instead of this OEM part?
While universal switches exist, HVAC technicians recommend using Source 1 York parts to guarantee that the set point matches the internal design of the heat exchanger and exhaust system.
