York S1-025-19499-001 Temp Control

The York S1-025-19499-001 Temp Control is a critical fixed-setting HVAC limit switch designed for precision thermal management in commercial air conditioning and heating units. This SPST temp control (Single Pole Single Throw) is engineered with a specific 65 degree open and 75 degree close logic, facilitating "close on rise" operation to ensure optimal system cycling and safety. As a genuine OEM York replacement part, it maintains the exact electrical specifications required for York E1CH120A25A models and compatible light commercial equipment. The robust construction and compact form factor allow for seamless integration into tight control assemblies where temperature-actuated switching is mandatory. For technicians performing field repairs, utilizing this York S1-025-19499-001 control switch ensures the circuit breaks at the 65°F threshold and resets precisely at 75°F, preventing rapid cycling and maintaining intended compressor or furnace performance standards.

• OEM Compatibility: Precision-manufactured to match the factory specifications for York E1CH120A25A units, ensuring a drop-in fit.
• Fixed Thermal Range: Features a calibrated 65Op/75Cl setpoint, providing reliable system protection without the need for manual adjustment.
• SPST Configuration: Simplified single-pole design reduces installation complexity and ensures consistent temperature control switch performance.
• Industrial Durability: Built to withstand the high-vibration environment typical of rooftop units and large-scale HVAC mechanical controls.

What is the function of the 65Op/75Cl setting?
This York temp control is designed to open the circuit when the temperature drops to 65°F and close the circuit as the temperature rises to 75°F. This specific temperature switch logic is vital for protecting system components from operating outside safe thermal parameters.

Which systems are compatible with part S1-025-19499-001?
This part is a direct OEM replacement for various York commercial platforms, most notably the York E1CH120A25A series. Always verify the model number on the unit’s data plate to ensure a match with the manufacturer's cross-reference.

Is this a universal HVAC part?
While it shares features with other limit controls, the York S1-025-19499-001 is an application-specific component. Using it in systems requiring different open/close differentials can lead to improper cycling or safety failures.
