York S1-025-26366-009 Temp Control

The York S1-025-26366-009 is a high-performance SPDT Temp Control specifically engineered for precision in heating and cooling applications. As a Single Pole Double Throw switch, this component provides versatile circuit management by either opening or closing electrical paths based on thermal thresholds. It is factory-calibrated to a 195°F Open and 130°F Close setpoint, making it an essential high limit switch for safeguarding HVAC equipment against overheating while ensuring automated system resets once safe operating temperatures are achieved. This OEM temperature control is a direct replacement for York S1-02526366009, built with a robust metal construction designed to withstand the high-cycle demands of industrial and residential furnaces or air handlers. Integrating this HVAC safety switch ensures your system maintains optimal thermal regulation across a variety of compatible York models. Professionals rely on this bimetal disc control for its consistency in preventing premature component failure and maintaining system efficiency without the need for manual intervention.

• Precise Thermal Regulation: Features a fixed 195°F opening point to prevent heat-related damage and a 130°F closing point for reliable resets.
• SPDT Configuration: Allows for flexible wiring in circuits requiring double-throw switching logic for diverse HVAC applications.
• Durable OEM Build: Manufactured to exacting standards to ensure a perfect fit and long-term performance in demanding environments.
• Universal HVAC Compatibility: Designed for seamless integration into York furnace parts and high limit control systems.

Is the York S1-025-26366-009 an auto-reset or manual reset switch?
This is an auto-reset temperature control, meaning it will automatically re-engage the circuit once the temperature falls back to the 130°F closing threshold.

What happens if my high limit switch fails?
A faulty limit switch may cause the blower to run constantly or cause the heat source to shut down prematurely. Replacing it with this genuine York part restores correct safety operation.

Can I use an SPDT switch to replace an SPST switch?
Yes, an SPDT (Single Pole Double Throw) switch can typically replace an SPST (Single Pole Single Throw) switch by utilizing the common terminal and either the normally open or normally closed terminal, provided the temperature ratings match.
