York S1-024-36052-014 Pressure Switch

The York S1-024-36052-014 Pressure Switch is a critical safety component engineered for precision monitoring of inducer fan draft within high-efficiency furnace systems. This genuine OEM high-altitude or standard-run switch features a factory-calibrated 1.7" WC setpoint and utilizes a SPNO (Single Pole Normally Open) contact configuration. Designed specifically to close on fall, this switch ensures the combustion sequence only proceeds when the burner box or heat exchanger maintains the necessary vacuum pressure for safe operation. This part is the direct updated version for the S1-024-25329-701, offering seamless backward compatibility for older furnace pressure switch installations. When troubleshooting, technicians should verify that the draft inducer is pulling sufficient vacuum to satisfy the 1.7" WC requirement. Using this inducer motor pressure switch ensures the system remains within peak performance specs while preventing lockout codes related to venting issues. Integrating this HVAC pressure switch into your service ensures a reliable, manufacturer-approved repair that maintains the integrity of the combustion cycle.

Key Benefits for Professional Installation

• OEM Precision: Calibrated specifically for a 1.7" WC threshold to prevent delayed ignition or nuisance tripping.
• Universal Compatibility: Serves as the official successor to the S1-024-25329-701, simplifying inventory management.
• Reliable Switching: SPNO architecture ensures the ignition control board receives an accurate signal only when safe airflow is established.
• Durable Construction: Built to withstand the thermal cycling and moisture levels typically found in high-efficiency venting systems.

Common Questions

What is the difference between this and the S1-024-25329-701?
The S1-024-36052-014 is the manufacturer-designated replacement for the older -701 model, featuring updated diaphragm materials for better long-term reliability while maintaining the identical 1.7" WC setpoint.

Can I use a "close on rise" switch if this "close on fall" switch is unavailable?
No. The logic must match the furnace control board's sequence. Using a switch with reverse logic will result in an immediate system lockout as the board will see the circuit as closed before the inducer starts.

How do I verify if the switch is failing or if it is a venting issue?
Technicians should use a manometer to measure the actual vacuum at the switch port. If the vacuum exceeds 1.7" WC but the SPNO contacts fail to close, the internal diaphragm or electrical contacts in the switch have failed.
