York S1-025-41329-000 Temp Controller

The York S1-025-41329-000 is an OEM replacement temperature controller engineered for precise thermal management in commercial and residential HVACR systems. This SPST (Single Pole Single Throw) switch provides reliable automatic reset functionality with a factory-set 26°F open and 38°F close configuration. Designed as a direct-fit component, it ensures seamless HVAC compatibility with York, Luxaire, and Coleman equipment, maintaining the integrity of the original system’s safety circuit. The switch operates on a "close on rise" logic, making it essential for low-temperature cut-out applications where protecting the evaporator coil from freezing is critical. As a genuine system sensor, it eliminates the calibration drift often seen with universal aftermarket parts, providing the exact electrical ratings and mechanical mounting required for a professional-grade repair. Contractors can rely on this York temperature switch to restore factory performance and prevent premature compressor failure due to improper refrigerant cycles or freeze-ups.

• OEM Precision: Genuine York component ensures perfect physical fit and electrical synchronization with existing wiring harnesses.
• Fixed Setpoints: Pre-calibrated 26°F open and 38°F close thresholds provide consistent thermal limit protection without manual adjustment.
• SPST Reliability: Robust single-pole design minimizes mechanical failure in high-cycle refrigeration environments.
• Automatic Reset: Self-correcting operation resumes normal system function once temperatures return to the 38°F closing point.

What is the primary function of the 26°F open / 38°F close setting?
This controller typically acts as a freeze protection switch. It breaks the circuit at 26°F to prevent ice accumulation on the coil and re-engages the system at 38°F once the ambient or surface temperature has safely risen above freezing.

Is this part compatible with non-York systems?
While designed for York S1-025-41329-000 specifications, it may cross-reference with other Johnson Controls brands like Coleman or Luxaire. Always verify the part number against your unit’s service manual for exact HVAC part compatibility.

Can I use a universal SPST switch as a substitute?
Field experience shows that universal sensors often deviate in sensitivity and setpoint accuracy. Utilizing this genuine OEM replacement preserves the engineered safety parameters of the HVACR unit.
