York S1-025-41046-000 Temp Control

As a field-tested York OEM replacement part, the York S1-025-41046-000 is an essential safety component for maintaining system integrity. This SPST temperature control, often utilized as a freeze stat protection device, is engineered with a specific 26 degree open and 41 degree close thermal response profile. In a typical refrigeration or HVAC circuit, this single-pole single-throw switch acts as a sentinel, breaking the electrical path when temperatures drop to 26°F to prevent evaporator coil icing and automatically resetting once the environment reaches a safe 41°F. This 15-degree differential is critical for preventing short cycling while ensuring continuous liquid line or airflow protection. Designed for industrial and commercial environments, it includes durable wire leads for secure integration into existing control logic. Whether you are performing a thermostat replacement or a furnace repair involving limit circuit diagnostics, this genuine York component ensures the precise temperature management required to protect expensive system hardware from freezing or overheating conditions.

• OEM Compatibility: Fits various York, Coleman, and Luxaire HVAC units as a direct genuine replacement part.
• Precise Thermal Cycling: Features fixed setpoints at 26°F (Open) and 41°F (Close) for consistent freeze protection.
• Automatic Reset: Eliminates manual intervention by re-closing the circuit once standard operating temperatures are restored.
• Rugged Construction: Built to withstand the harsh vibration and thermal fluctuations common in commercial air handlers and rooftop units.

• Can this be used as a high-limit safety? While similar in design to a high-limit switch, this specific model is calibrated for low-temperature detection (26°F/41°F), making it suitable for coil freeze-up prevention rather than furnace over-temp protection.
• Does the switch have continuity at room temperature? Yes. Since the 'close' temperature is 41°F, the switch should remain closed at room temperature, allowing current to pass.
• How do I verify if the switch is failing? If the system is short cycling or disconnected despite being above 41°F, use a multimeter to check for continuity across the SPST switch terminals.
